The Basic Composition of Lithium-ion Battery and Main Materials
The basic composition of lithium-ion battery and main material, lithium -ion battery is a chemical power . ① two electrodes cell redox reaction in progress , respectively, must be carried out in two separate areas , which is different from general oxidation-reduction reaction . ② When two electrode active material undergo a redox reaction , the desired electron must be transferred from an external circuit , which is different from the micro- cell reaction corrosion process . In order to meet the above conditions , no matter what the battery series , shape , size , by the following components : an electrode ( active material), electrolyte, separator , binder , a housing; in addition to positive and negative electrode lead , the center terminals , insulating material , the safety valve , PTC ( positive temperature control terminal ) and the like are also an integral part of the lithium ion battery . The following briefly describes the
