Zusammenfassung: | The utility model relates to an anti-explosion lithium battery structure and a mobile phone battery. The lithium battery structure comprises a battery cell arranged in a shell, the explosion-proof battery terminals are arranged at the positive electrode end and the negative electrode end of the battery cell; a ceramic layer is arranged on the inner surface of the battery cell, and an insulating layer, a heat dissipation layer and a waterproof layer are sequentially wrapped on the outer surface of the battery cell; the first explosion-proof layer and the second explosion-proof layer are arranged on the battery terminal, so that the internal pressure of the battery body is released at proper time, and the safety of the battery is ensured; through the arrangement of the ceramic layer, the thermal runaway caused by thermal shrinkage is solved, the ceramic composite diaphragm has good infiltration and liquid absorption and retention capabilities with electrolyte and positive and negative electrode materials, and t |
