The principle and structure of lithium battery

The structure and working principle of 1, lithium ion battery: lithium ion battery refers to the so-called respectively by two reversibly embedded and de compound lithium ions as the positive and negative electrode composed of two batteries. People will transfer this by lithium ion in between the positive and negative electrodes to complete the battery charge and discharge of the lithium ion battery work, the image of the unique mechanism called "rocking chair battery", commonly known as "lithium battery". In the case of LiCoO2: the charging the battery, lithium ions from the cathode in the de embedded, embedded in the cathode of the discharge, and. This requires an electrode is in before assembling the intercalation state, the general choice of lithium in terms of relative potential is greater than 3V and is stable in the air of the lithium transition metal oxide as positive electrode, such as LiCoO2, LiNiO2, LiMn2O4, LiFePO4. The anode material is select potential can be embedded lithium compounds as close as possible to the lithium potentials, such as various carbon materials include natural graphite, synthetic graphite, carbon fiber, mesophase microbead carbon and metal oxides, including SnO, SnO2, tin oxides SnBxPyOz (x=0.4 ~ 0.6, y=0.6 ~ 0.4, z= (23x5y) /2) etc..


2 the battery generally include: positive (positive), negative (negative), electrolyte (electrolyte), the diaphragm (separator), the positive electrode lead (positivelead), the negative electrode lead (negativeplate), the central terminal, insulation materials (insulator), the safety valve (safetyvent), the sealing ring (gasket), PTC (positive temperature control terminal), battery shell. In general, we are more concerned about the positive negative electrode, electrolyte
