Categories of the harga power bank

There are only two kinds  batteries classification of harga power bank, one is an ordinary lithium batteries, not outside a polymer batteries. Both in the material and shape of the above there is a big difference, according to the national standard battery, especially for polymer battery has a strict grading system.

An ordinary lithium batteries

Advantages of ordinary lithium batteries: lithium batteries because of the development time of more distant common battery relatively inexpensive Disadvantages: Waste refurbished batteries more, because the process causes the problem rate and failure rate remains high, bulky heavy weight. Service life is short and there is likely to cause an explosion, the current mainstream mobile power are phasing out these batteries, at a later date, the ordinary lithium batteries will gradually withdraw from the stage of history in power bank factory.

2 polymer batteries

The lithium-ion battery electrolyte materials used in different lithium-ion batteries of powerbank can be divided into liquid lithium-ion battery, referred to as LIB) and lithium-ion polymer battery (polymer lithium ion battery, referred to as LIP) into two categories. Positive and negative materials with liquid lithium ions are the same, polymer lithium ion battery cathode material used can be divided into lithium cobalt, lithium manganese oxide, lithium iron phosphate ternary materials and materials, graphite is extremely negative, the battery works are basically the same. The main difference lies in the different electrolytes, liquid lithium ion battery using a liquid electrolyte, and lithium ion polymer batteries places instead of the solid polymer electrolyte, the polymer may be a "dry state", can also be in "colloidal ", now most of the use of polymer gel electrolyte.
