Basic knowledge of cell phone batteries

The so-called lithium-ion battery is able to absorb Tibet out of the carbon material of the lithium-ion battery as the negative electrode active material, lithium-ion symbol for the Li-ion. We all know that the batteries are generally the basic elements of the cathode, anode, separator, electrolyte composition, then these materials are generally used in lithium-ion battery is the following substances:

Cathode: lithium cobalt oxide (LiCoO2), lithium nickel (LiNiO2) manganese lithium (LiMn 2 O 4);

Negative: the series of artificial graphite, natural graphite series, coke series and so on;

Membrane: Polyethylene (PE), Polypropylene (PP), consisting of single or multi-layer micro-porous film;

Electrolyte: acrylic ester carbonate (PC), ethylene carbonate (EC), dimethyl carbonate (DMC), diethyl carbonate (DEC), methyl ethyl carbonate (MEC) and other one two yuan or ternary mixtures

The lithium-ion batteries sold in the market are mostly based on lithium cobalt oxide cathode, graphite series to the negative battery.
