Lithium ion battery has production liquid lithium ion battery (.lib) and polymer lithium ion battery (LiP) two kinds. Therefore, in many cases, the battery labeled the Li ion – the lithium ion battery, must be. But not necessarily liquid lithium ion battery, also may be polymer lithium ion battery.
Lithium ion battery is ameliorated lithium battery products. Lithium battery has long ago, but the lithium is a highly active (remember it in the periodic table of the position? When the metal, it is used not quite safe, often in charge when combustion, burst, and then there is the model of lithium ion battery, joined can restrain the lithium elements of active ingredients (such as cobalt, manganese, etc.) which li-ion battery truly achieve the safe, efficient, convenient, and lithium battery and basically eliminated. As to how to distinguish them from the battery, sign can identify, lithium battery for Li, lithium ion battery for Li – ion. Now, my notebook and mobile phone use of so-called “lithium battery”, actually is lithium ion battery.
The basic structure of the modern batteries included positive and negative and electrolyte three elements. As a kind of battery, lithium ion battery has the same three elements. General lithium-ion technology using liquid or inorganic gel electrolyte, so need to accommodate flammable solid crust of the active ingredient, it increases the weight of the battery and cost, and also limit the size and shape of flexibility. Generally speaking, the liquid lithium-ion secondary battery, the minimum thickness is 6mm reduction is more difficult.
The so-called polymer lithium ion battery is in the three main structures in at least one or more using polymer as its main battery systems. The new generation of polymer lithium ion battery in chemical polymerization degree of already high, so can be done on the shape of the thin thin shape (0.5 mm), and the area of arbitrary shape, and greatly improve the flexibility of the battery, the modelling design can be made with product demand, any shape and the capacity of the battery. At the same time, polymer lithium ion battery energy per unit of the general lithium ion battery capacity increased by 50%, the charging and discharging characteristics, safety, and working temperature range, cicyle life and environmental performance etc. A lithium-ion batteries.
Now that the liquid on the market sales lithium ion battery (.lib) in charge of the excessive cases, easy to cause the relief valve, and the broken this is very dangerous, so must add protection IC line to ensure the battery charging excessive won’t happen. And polymer lithium ion battery, this type of battery relative liquid lithium ion battery charging and discharging has good resistance to protect, plus the IC circuit requirements can relax appropriately. In addition, polymer in rechargeable lithium ion batteries can be used with current IC, rechargeable lithium ion batteries used CCCV Currert you (you) charging ways – by the time needed for comparison, can shorten the time of waiting for many.

Mobile phone manufacturers of lithium battery application
Although in recent years, almost all manufacturers have tended to using lithium ion battery, but the major mobile phone manufacturer for battery choice or have their own characteristics and habits, such as ever in the same period of time:
Nokia: Ni fd-mh nimh batteries, (.lib (liquid) lithium ion battery, adopt LiP) (polymer lithium ion battery).
Eric: Ni fd-mh battery, the battery, the battery LiP libs.
MOTOROLA: Ni fd-mh battery, the battery, not by consulting the LiP batteries.
We find the phone to choose from LiP polymer lithium ion battery on the matter, Ericsson mobile technology pioneer embody themselves. According to the material that I find, polymer lithium ion battery factory for Japan mainly SONY, panasonic, GS, several companies, 2000, the production of 21 million 50% for Ericsson mobile phone. Enter 2002 today, lithium ion battery in other mobile phone manufacturers also has wide application and popularization. But in polymer lithium ion battery, still far from mobile phone manufacturers in all the products in the popularity of the widely remains.
On the other hand, although the lithium ion battery, but also has many advantages, such as high prices and defect charge less number, etc. The number of charging and discharging lithium battery only 400-600 times, specially improved product also but 800 times. But the nimh batteries charging times can achieve 700 times above, some good quality products can reach 12 times, charge is such a nimh batteries, than lithium battery life. In addition to the price of nimh batteries are much lower than lithium batteries. But strictly speaking, lithium battery will also have memory effects, but its memory effect is very low, basically be ignored.
Thus, there is no perfect batteries.lithium battery
