How do you distinguish power battery from capacity 18650 lithium battery?

1, 18650 performance lithium battery anode materials mainly is more tiny particles than the average 18650 lithium battery energy density is not large, the diaphragm materials and electrolyte conductivity, better conductive performance is better.

2,18650 power lithium batteries across the electrodes in the derivation of a material has more than ordinary 18650 lithium batteries (reduced ear resistance and satisfy more current).

3,18650 power battery support large current discharge, could reach 30 c ratio of current, 18650 normal lithium battery only support 1 c discharge rate.(1 c is equal to the capacity of 1 ratio capacity)

4, 18650 power battery capacity is generally smaller than a regular lithium battery capacity 18650 1/2 or so, if the capacity of 2000 mAh power model 2000 lithium battery capacity of only 1000 mah5, general type 18650 lithium battery charging voltage is 4.2 V, power type 18650 lithium battery charging voltage is 3.65 V or so.Ordinary type capacity 18650 lithium batteries nominal voltage is 3.7 V, power 18650 lithium batteries nominal voltage is 3.2 V.

5, "lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution.Lithium battery as early as 1912 by GilbertN. Lewis is put forward in this study.In the 1970 s, M.S.W hittingham and began to study are put forward lithium ion batteries.Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment.So, the lithium battery has not been applied for a long time.With the development of science and technology, the lithium battery has now become the mainstream.

6, the lithium battery can be roughly divided into two categories:Lithium polymer battery and lithium ion batteries.Lithium ion battery does not contain lithium metal state, and can be recharged.The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries.Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.
