Currently on the market used mainly in nickel-metal hydride secondary battery (Ni-MH) and lithium-ion (Li-ion) types. Lithium-ion batteries have been mass production of liquid lithium-ion battery (LIB) and lithium-ion polymer battery (LIP) of two kinds. Therefore, in many cases, the battery mark on the Li-ion Laptop battery should be lithium-ion battery. But not necessarily that of liquid lithium-ion battery, also possible that the polymer lithium-ion battery.
Lithium-Ion battery is a lithium improved products. Lithium batteries have a long time ago, but lithium is very active (remember its location in the periodic table do?) In metal, it is not very safe when used often in charge when burning, burst position, then there is an improved lithium-ion batteries, lithium can inhibit the added element of active ingredients (such as cobalt, manganese, etc.) so that lithium achieve truly safe, effective, practical , while lithium batteries will also former largely eliminated. As for how to distinguish them from the label of the battery will be able to identify, lithium battery for Li, Lithium-ion IBM ThinkPad T40 battery for Li-ion batteries. Now, laptops and cell phones using the so-called “lithium batteries”, in fact, are lithium-ion battery.
The basic structure of modern batteries, including tubes, anode and electrolyte of three elements. As a kind of lithium-ion battery also has these three elements. General-technology lithium-ion battery uses a liquid electrolyte or gel inorganic shell requiring a solid fuel to accommodate the active ingredient, which increases the battery weight and cost, but also limits the size and flexibility of styling. In general, liquid lithium-ion secondary battery is a minimum thickness of 6mm, a further reduction on the most difficult.
Lithium is known as polymer-ion batteries are the three main structures in at least one or more of the use of polymer materials as its main battery system.
A new generation of polymer lithium-ion polymer Dell Inspiron B120 battery technology is already very high, if the form can be thin (thinner than 0.5 mm), any size and any form of greatly increased battery Design Flexible, it may therefore respond to the request, made any shape and capacity of the battery. At the same time, polymer lithium-ion battery pack energy than current lithium-ion batteries in general has increased 50% capacity load discharge characteristics, safety, the operating range of temperature, cycle life and environmental performance in such aspects as compared to lithium-ion battery large rate increase.
Currently marketed in liquid lithium-ion battery (LIB) where over-charging the battery, and therefore likely to cause safety valve ruptured fire situation, it is very dangerous, if the need to protect the IC circuit installed to s’ ensure that the battery is not on – in charge of the case. The lithium ion polymer battery, this type of lithium battery-ion batteries in terms of liquid relative has good resistance to load and unload features, adding requirements external circuit protection IC may be suitably relaxed. In addition, in the charge, the polymer lithium-ion batteries can take advantage of the IC load current constant, and lithium-ion secondary sony VGP-BPS5 battery used in CCCV Currert (Constant-voltage constant) load means the time required for comparison can shorten a lot of time waiting.
Although the advantages of lithium-ion battery package, but there are gaps, such as charge and discharge times of high prices and less. Lithium loading and unloading of the number of times 400-600, specially modified products, but many times 800. Nickel-metal hydride rechargeable batteries for more than 700 times to obtain a certain quality and a good product charge and discharge up to 1200 times, so a comparison, the nickel-metal hydride battery live longer than lithium batteries. In addition, the price of nickel-hydride batteries in metal is also much lower than lithium batteries. Moreover, strictly speaking, lithium batteries have the same memory effect, except that it is indeed very little memory, it is essentially negligible.
Thus, there is no perfect battery.
