About Li-ion batteries and their advantages and disadvantages

Li-ion battery came from lithium-evolved. Therefore,before introducing the Li-ion, we must introduce lithium Dell precision m90 series battery first. For example, the former camera button cell lithium batteries belongs to Li-ion battery. cathode material of Lithium battery is lithium metal. Anode material is carbon material, we call this cell as lithium batteries.

Cathode material Li-ion is lithium cobalt oxide, cathode material is carbon material. Lithium-ion Sony np-fp70 battery go through the cathode material of the type of carbon in the negative and move out to achieve the battery charge and discharge process, so people called Li-ion.

1. The single cell for Panasonic cga-du21 voltage is up to 3.6-3.8V;


2. The large energy. Present HYB Battery steel can achieve more than the actual energy 100-135W.h/Kg and 280-353W.h / L (2 times and Ni-Cd, 1.5 times the Ni-MH)


3. Long cycle life. Li-ion Dell xps m1330 battery can reach 500 times more than normal in general, or even 1000 times.


4. Safety performance is good, pollution-free, no memory effect. As the predecessor of lithium Li-ion batteries,Kodak klic-8000 , due to the formation of dendrite lithium lithium easily and short-circuit, this shorten its applications; Li-ion does not contain cadmium, lead, mercury and other elements of the environment pollution; part of the process (such as around the node-type) and Ni-Cd batteries there is a major drawback for the "memory effect", it seriously hindered the use of batteries, but Li-ion Kodak klic-7004 battery does not exist this problem.

1. Dell precision m series battery costs are higher. it mainly reflected in the price of LiCoO2 high (Co fewer resources), and electrolyte purification system is difficult.


2. Can not be high-current discharged. As the organic electrolyte system, and other reasons, compared to other type of batteries, the battery internal resistance is more larger, so we called for a smaller current density forJVC bn-vf823 Battery
   , generally ithe discharge current is 0.5C below,it is only suitable for small and medium-current electrical to use.


3. Iit need to protect the line control.
   
   
4. Small self-discharge. Room temperature, full power Li-ion Dell inspiron 3500 d300gt battery storage 1 month self-discharge rate is about 10%, it is much lower than Ni-Cd of 25-30%, Ni-MH 30-35%.
