digital batteries

Fruit of the battery is inserted inside the chemical activity in fruits of different metals, such as fruits, electrolytes that are acids can form a galvanic cell.

Fruit batteries generating principle is as follows: two types of electrochemical activity metal is not the same, which side of the keenest sheet metal may be a replacement of acidic substances in fruits and hydrogen ions, as produces a positive charge, the whole system need to maintain stability (or generate electric field, electric field caused by the results below), so the composition of cases, the original Laptop battery, the electrons circuit to maintain system stability, so in theory the current size of the concentration of direct and acid linked to (if it is expressed in terms of the case, then this function and the ionic strength but also Quantitative and qualitative relationships relationship between plasma concentration), in this case, if the loop length change, which would inevitably change the loop, it will also cause changes in voltage.

Fruit production of batteries

Do you know that certain fruits and vegetables you eat can also generate electricity do? Try the following experiment!

Tools and Materials

• 3 lemon (lime may be)

• 3 pieces of bright copper Ge. We use the coin

• 3 Ke galvanized screws (you can also use other metals more active, not necessarily zinc, both for replacement on the list)

• 4 son, preferably with a clip on the wire.

• Knife • 1 small paper label pasted

• Low voltage driven light-emitting diode (LED). We use Radio Shack model 276-330.

• 35 rounds mm plastic film or similar small container. Better to use a black hull opaque film.

• a nail or small punch

Zinc-plated screws are available in most hardware stores. They are also known as “electroplating” screws. For galvanized screws to prevent them from rusting, which makes live appearance looks bright. Wire belt clip can be purchased at hardware or electronics store.

Production Method

First, put all the lemons, one at a time. Side of the rotating part of the hand pressing them until you think they have become a little “soft.” This is done to allow internally generated more lemon juice. This step is very important because it can help you achieve the best results of the lemon Dell Inspiron 1420 battery.

Be galvanized screw screwed into a lemon about 1 / 3. Using a knife, be careful with the lemon on the other side 1 / 3 Cut a 1 cm incision.

Note: The best use of a knife by an adult. In all cases, please “watch” and “Slow” using a knife.

Copper in the incision until the coins in half lemon.

Note: Make sure you use a shiny new coin. If the room in the former, but not brilliant, polished with 100 JIES parts.

Whether or not you believe that you can now get underway lemon! Like other batteries, such as coins, is the positive (+) The screw is negative (-). Unfortunately, the battery is low. However, if you have several of these cells, they can be connected together to form a lemon battery.

As the parts and screws in the other two lemons. Then, using the son and clips, will be the first of a lemon on the screw with the second piece on the whole lemon, and so on, there are three lemon cells connected together. Also a coin to the first and last of a screw connected to a wire with a clip.

Finally, to connect to the first sequence on the part marked “+” and connect to the last screw nailed clip marked “-.” Like a real battery, as the lemon battery is also positive (+) and negative (-).

When the series of articles, these lemon co-produced the battery cells in series with a small flashlight, some produced by the same voltage, or electric potential of about 2.5 volts to 3 volts between the two . But the lemon battery can not produce enough current to the bulb flashlight.

How can we identify the achievement of specific groups of the battery? One way is to require only 2.5 volts to 3 volts, and does not require too much current, the electrical equipment connected to the hp Pavilion dv4 battery. Can use a device known as light emitting diodes can also be called LED. Very low voltage and low current can make the LED light.

The LED used the instructions on the box are 5 mm red LED, 1.8 volt, 20 mA. This means that the diameter of 5 mm LED, it requires 1.8 volts and 20 milliamps of current can be slight. In fact, less than 20 milliamps of current can make a little light-emitting LED. Our lemon battery has enough voltage, but current is not sufficient. We must find ways to observe the faint light. We will film in the shell to cut the outside light.

The use of nails, be careful in the film about half of the outer envelope of the two small holes where the top. Allows an adult to help you achieve this step.

Then a small hole marked “+” another labeled “-.”

PIN LED will be folded into a smooth curve outward. Then, to observe carefully closing LEDs. It is mostly round. However, if it is placed at a specific point of view, you will see a pin near a flat surface. From this plane, the last pin is the anode. Pictured from left pin is the negative terminal of LED. You can see the left-most pin in the vicinity of the surface of the small apartment, do?

The negative pin and the LED marked “-” alignment film shell hole. Will run shell pressed film. Thanks to the LED cathode to the pin marked “-” the hole, then make another (positive) pin through the words “+” hole.

Pull The Pin by the holes and departure to ensure they are marked with the slogan. Film also top of the label on the shell. OK LED to us.

We must all be prepared to wait for the last minute. While the film contains a shell LED marked “+” side of the sony VGP-BPS2A battery alignment lemon marked “+” clip. Lemon battery is marked “-” in the film clip to close the envelope marked “-” side.

Now everything is ready! The LED cathode is connected to the lemon battery positive electrode. The LED cathode is connected to the negative terminal of the battery lemon. LED light!

But the hair of the LED light is very dark, because the current battery is too low. Shells film noir that can help you out in dim light. LED end of the play the role of a magnifying glass. When direct observation of the end of the LED, you can easily see the phenomenon of light.

This proves that you really can be used successfully produced a lemon battery! Congratulations!

Troubleshooting

If you can not see the LED light, try the following methods:

1. You may get anti-polarity of the LED, which is positive and negative reversed. First, a livelier place is the oxidation of the metal, it is more lively foil for the anode and the other end, against less active metal anode. Reverse LED and see if it is light.

2. LED light emitted can be very dark. The LED in a darker room, and make the eyes before the experiment to adapt to lower light.

3. Make sure all connections are secure: to ensure that the clip metal parts VGP-BPS9 and screws the connection there is lemon in pieces and screws are solid.

Platinum Precision Equipment Co., Ltd. Chairman Peng Yang Libin said December 8, the next “New Energy Industry Promotion Plan in 2020, China has the production capacity of photovoltaic electricity will reach 20GW, which means that Solar energy is an average annual 2GW increasing the speed of space for future development of a huge solar energy.

It is understood that the platinum thin-film yang Seiko production equipment from the battery to over 30% gross margin, while the use of company equipment on cell panels to achieve the lowest production costs $ 0.75 per watt, they are practically in the lower ranks of the world, the Ming and the year after next be able to do less.

Thin-film batteries is expected to lead

Peng said Libin Technology amorphous silicon thin film technology to traditional crystalline silicon significantly different from polycrystalline silicon in the process of refining a lot of energy, the cost is relatively expensive, low-purity polysilicon to our country faces a serious problem of excess, the Government of the polysilicon industry related to restrictive policies, while the thin film technology because of its energy saving ecological features, will become the future direction of technology.

It is understood that in the United States, the thin part of the film battery market is rising, while the technology of crystalline silicon cells is showing the market share continued to decline. Crystalline silicon cells in the past to many battery manufacturers buy thin film production equipment, tried to enter the market thin film IBM ThinkPad R52 battery. Analysts estimate that the majority of these companies to buy foreign equipment is often confronted with problems of high cost.

According to Peng Libin describes the principal activity of the business is the manufacture of amorphous silicon based thin film solar PV manufacturing equipment, module development and production programs, available to downstream components of the activity battery. Which one company sells equipment, completion of the first half of this year, 10 million orders.

Platinum Yang Seiko is the only access to China’s solar cells TUV / IEC (European Certification Center) and UL (USA CA) dual-certified supplier of complete sets of equipment. This also allowed Yang Seiko platinum market in the United States and Europe to obtain a green card.

The lower power production costs

Peng said Libin, our price to come photovoltaic benchmark may be set at 1.1 yuan / kilowatt-hour or so, the future of May that the lower price, it is impossible to improve. Undoubtedly, the future be able to effectively control costs, manufacturers have access to a larger living space.

Platinum-Yang Seiko equipment suppliers as a thin film Dell Inspiron 8500 battery, located at the top of the industry chain, to put in place to provide equipment manufacturers, industrial chain, the terminal is the power plant, if the plant availability downstream reasonable and affordable access to internet prices, not only to the survival of upstream suppliers, but also related to industry, health, sustainable development.

According to Peng introduction Libin, the use of platinum thin film battery Yang production of precision equipment produced panels, enabling the administration to reach the photovoltaic power stations, electricity price 1.06 yuan / kWh or less than the previous tender Dunhuang PV determined with 1.09 yuan / kWh price. However, many battery cells are concerned traders, that price is still unprofitable.

Peng Libin said, according to forecasts, the equipment business and technology upgrade, the company produces solar panels next year, should enable the realization of the price of electricity facilities Power 1 yuan / kWh the next two to three years will allow the Internet to obtain a unit price of thermal energy with the core level flush water reaches its maximum.

The use of company equipment on board, the production cost less than $ 1 per watt, they are mainly in the ranks lowest in the world. Libin Peng said the company equipment to produce thin hp Pavilion dv4 battery costs because of the film are so low, first, is the large scale production, the company has focused on the other hand, is in research and technological development, technology company primarily in the United States has been in the current U.S. patent period of protection technology based on the achievement of technical advantages, the company also plans to invest the next three years more than 100 million U.S. dollars to research on related technologies, and development costs.

Laptop battery structure is not complicated, the simple answer is that the batteries with protection circuit, the battery is at the heart of batteries in series or parallel, where one usually sees on the batteries with the generally cylindrical similar to the fifth battery just inside the stored energy of the chemical solution from different manufacturers have designed more current, over voltage, over charge, over discharge, temperature, etc. to protect.

Cellular structure, even if a simple, but really qualified to make a battery is not so simple. A product must first select the batteries, the batteries are often poor internal resistance, voltage, charge and discharge targets difficult to meet demand, to do outside of the product is mixed. Currently several regular-purpose manufacturers Sanyo, Samsung, Toshiba, LG, Bak and other brands of batteries. After storage piles should be tested for their targets and indicators in the 2% difference in the batteries can be combined in series or parallel circuit composed of, if not a target of batteries and other batteries because of very different in the IBM ThinkPad R51 battery charge-discharge process will be expressed in the form of charging or discharging the battery have not yet succeeded, and that person was on battery charge or discharge, resulting in the battery does not work The difference in the long term, larger batteries, or over-charging after discharge, leakage or even an explosion that may arise. Manufacturers of battery test and matching precision instruments and equipment, the computer generally rely on the city known as the professional maintenance staff will be able to complete the multimeter, and they rely on a multimeter can be achieved at best is to check the battery internal resistance within the accuracy required, as actual battery storage, life, load and discharge the effective time, no equipment professional may not detect a real sense can not be matched, said maintenance is also a form, the storage battery maintenance has not increased is not.

Laptop battery life is typically 300 times the total charge and discharge, and half a year or two to replace a new battery, laptop batteries home are not cheap, easy miles, a few friends to spend no so much money to buy laptop Dell Latitude D800 battery replacement while the thought of batteries, which should not be? This security risk it?

At this point, I visited the electronics market, engage in commercial transactions, both second-hand phones, “said the writer who can provide what they call” change of base” maintenance department. In the author in the hands of IBM 600E batteries original equipment, for example, “to the” core costs about 100-300 yuan, and its process is very simple, you come from a welding equipment and technology base can be completed. In keeping laptop battery site, the reporter saw the repair personnel forced the original battery, will the old batteries out, then it is in compliance with the new batteries in place in turn connected to future and the whole process should not exceed 30 minutes. “In fact, most laptop batteries are not rechargeable batteries as a result of aging, as the battery and the control board’s discharge circuit is not evil, this servicing almost 100% Success. “Merchant said:

Maintenance Activity has also revealed that the batteries are currently in circulation in developing countries to purchase large quantities. Repairs inside the hp Pavilion dv4 battery until earlier this year, appeared in large numbers on the local market for electronics, but also very popular. “In the ‘Fast blue’, where the block to buy a new battery at least 1,000 yuan more than the price that many customers are less expensive to come to this for Ben Zhao. ”

I interviewed a number of IBM products is responsible for after-sales service “Blue Express” staff to “change the basic behavior that they have both said that did not know, has not proceed with a complaint from a customer. However, a staff member confirmed that the purchase of a new 600E battery needs to spend about 2,400 yuan, one can say is equivalent to half the price of a mobile home.

For the difference between the price gap, “Blue Express” the head of the Propaganda Department, said, IBM has its own pricing strategy worldwide, the company does not change the permissions, but if you opt to repair the Battery is the freedom of the client. At the same time due to environmental considerations, IBM customers will be given to scrap batteries, commanded by professional companies to focus on destruction, the process takes a lot of money.

Given the “cheap appeasement” of the laptop battery for the central process, professionals advise that the essence of “change” cell there is a security risk.

“Blue Express” the technical staff, told Reporters Without authorization “for the core,” there is a big security risk, some rechargeable batteries without detection of short-circuit even after the bursting phenomenon, ranging from damage to host, while in the explosion, and even life threatening for the user. It’s really unwise to be too expensive, not as good as the batteries of laptop OEM buy. In Indeed, many claimed to be original battery is OEM like Dell’s brother, there are parts that are not OEM? Batteries for laptops OEM manufacturers of batteries are imported actual performance and few differences of origin because it is produced locally (mainly in the south, some manufacturers), low cost and no import tax to pay so much, so only one third the price of imports or less. In addition to the sony VGP-BPS5 battery purposes of basic insecurity, the provision of basic services for businesses and maintaining the level of uneven quality, inside and chat in a company, some Black Hearted providers battery maintenance to earn huge profits, taking the quality of the best moments cells act as a good battery, and worse, the battery inside the controller chip removed, but only one wire connected to, or have already been demolished on the circuit inside the battery some. Tell a serious argument, so that the battery can not think are all very hard.
