Separator

The battery separator plays a major role in lithium ion battery conduction lithium ions and isolation between the positive and negative electrode electronic contact. It is an important component to support the battery to complete the electrochemical process of charge and discharge. In the use of lithium batteries, when the battery overcharge or at higher temperatures, the separator ...

Lithium Chip Metal lithium chip used in the laboratory can provide a far greater source of lithium, Lithium chip shall have less impurities and the size shall be larger than that of the electrode to be measured, and the purity of lithium chip shall not be less than 99.9%. General requirements for lithium chip in the preparation of coin cell: diameter 15 ~ 15.8mm (the corresponding electrode size i...

The lithium battery separator acts as a protective barrier between the positive and negative electrodes, conducting ions but not electrons. In the ideal state after electrolyte filling and formation, the separator should maintain complete and flat contact with the electrodes. However, when we disassemble batteries, we often find severe wrinkling of the separator. (This can also be clearly observed...
