The safety problems of laptop cell

Two kinds of import laptop cells and one kind of domestic laptop cell were investigated based on impact test,crushing test and cell protection against a high charging rate test.The results showed that the safety performance of the imported laptop cells was better than that of some domestic laptop cells,and one domestic laptop cell was burnt in crushing test.Therefore,some domestic laptop cells still had some hidden safety problems and there was a long way to go to investigate and improve the safety performance of domestic laptop cell.
