We must eliminate the gasoline cars pollute the environment and the development of new energy vehicles, but used in the production process and recycling of batteries of pollution on human health, it is worth?
Fuel cells, hybrids, pure electric, three sets of new energy vehicles, and more hybrid cars must use oil, the rest has no oil.
The first with hydrogen, the latter with the power, it is known as green products (hybrids can reduce exhaust emissions).
It is expected that the loading of the Laptop battery power of hydro, wind, sunlight, power nuclear energy, thermal energy is also the valley of the night to use their power. This green energy sources and renewable electricity, of course. Hydrogen production from renewable electricity. Of course, hope that one day these ideas can become reality. Three sets of cars need to use the storage battery power or auxiliary drive vehicles, or vehicle main engine. The battery industry is currently the main strategy of the lithium battery. In the hybrid with the original nickel-metal hydride battery-based, pure electric vehicles using lead-acid battery Uehara.
Now the industry for several batteries or controversial, which one is better than both merits and demerits. Li-ion battery as the energy that can quickly download large load can quickly adapt to a wide range of temperature. In recent years, a greater increase in performance, the cost has decreased considerably, people placed great hopes. However, a relatively large number of constraints, is a technology development, research and development that require research.
Lithium resources of the world’s 15 million tones, China about 390 million tones, about 28% of world total, ranking second in the world. It is estimated that 1 g lithium metal Dell Inspiron 700m battery can be about 0.6 ~ 0.8Wh (and the synthesis of cathode materials related to materials and synthetic related to the negative performance of the electrolyte and synthetic).
For a compact car, for example, electricity consumption per 100 km of pipe approximately 15 units of electricity, online renewal mileage of about 150 km, the lithium storage capacity in the 30kW / h ~ 35kW / h, the group of lithium batteries lithium metal contained in 50 kg above, equivalent to about a mobile phone battery (rechargeable batteries 3.5Wh) 10,000 times. 121 Beijing Road, a model of pure electric passenger large, its total storage capacity of the lithium battery is said to 160kW / h, the total weight of about 2 tons, the lithium metal content is approximately 280 kg or more.
Toyota Prius hybrid is the use of nickel-hydride batteries in metal, but the storage capacity is not. Small reserves of nickel is used in electroplating, coins, stainless steel must be important. Lead-acid batteries oldest and most mature, maintenance free type has been widely used in many ways two-wheeled electric vehicle, costs may also be 3C-load current and the discharge can be of 2 hours and the rate of discharge current. Lead is rich in resources, huge production of China, representing about 40% of the total world. However, the refined lead metal, lead plate manufacturing, assembly of hp Pavilion dv2000 battery and recycling of waste batteries and regeneration of various links workers to harmful pollution of the environment. The consequences are increasingly shows that after a century of lead acid batteries, tough, with its space needs for energy storage is mainly used in soil, a large number of vehicles used must be controlled .
Lithium, nickel limited resources, need to use up too much power to the car battery is a disposable, not a path towards sustainable development. With lithium, nickel resources, the substitution of the limited resources of oil, it is not wise. Pollution, lead acid batteries can not be avoided, can the less the better. To replace the pollution it generated emissions of greenhouse gas emissions in the internal combustion engine, an exercise is a tiger wolf.
If we actually use lithium, nickel-metal batteries that traction and equipment in vehicles with new energy, and is also the industrialization of new energy vehicles, but also exported, so that enough resources for few years? Should not be used for other purposes? (Bus one group of lithium to 2 tons, while the lithium metal is about 280kg. Ni-MH VGP-BPS2C battery of about 4 tons and nickel how much, no one has published data).
If we use equipment of the lead acid battery, electric cars, electric buses, and the year may change a battery, then the large amount of surprise. Beijing City Bus has lead acid batteries, weighing about 6 tons, a compact car needs a hundred kilograms (maintenance free lead-acid battery-based storage capacity of its 35 – 40Wh / kg, while riding a bus if 60 people, the number of quality of care, certainly not 6 tonnes. It is 6 tons of batteries installed in the slope of the vehicle forward every day to and since the technique probably unreasonable, undesirable.
We develop new fuel-efficient vehicles (electric), replacing the oil on a tight end in itself, but to consume less resources, lithium, nickel-metal that science? Viable? We must eliminate the gasoline cars pollute the environment and the development of new energy vehicles, but used in the production process and recycling of batteries of pollution on human health, it is worth?
Energy vehicles Consequently, at present, new, if you want to use this storage device and energy storage means, it is necessary to explore his identity. Currently at prototype stage demonstration turned too late. “DDT” jokes will not be repeated here.
