　　After these lithium ions are electrons, lithium atomic crystals will be generated on the outside of the data, which will form dangerousness like over -charging. In case the battery shell breaks, it will explode. Therefore, the protection of lithium -ion batteries must include at least: the upper limit of charging voltage, the lower limit of discharge voltage, and the upper limit of the current. In general, there will be a protective board in the lithium battery group, except for the lithium battery core. This protective board is mainly to provide these three protection.

　　1. Large internalization;

　　2. Water absorption, react with electrolytes;

　　3. The quality and function of the electrolyte itself;

　　4. The amount of injection in injection does not meet the process requirements;

　　5. The laser welding function is poor during the assembly process.

　　6. Dust and film dust are primarily easily leading to micro -short circuits;

　　7. Positive and negative films are thicker than the process range, and it is difficult to enter the shell;
