High magnification explosion-proof lithium battery structure that this utility model provides and the fixing means of battery and box hat, have following
Beneficial effect: 1, battery realizes fixing in box hat by slot rolling position, box hat two ends.2, both positive and negative polarity all uses explosion-proof cap, anti-
Quick-fried effect is more preferable, safer, and the design of new type explosion proof lid makes explosion-proof performance improve.3, both positive and negative polarity lug uses multi pole ears, current-carrying
Area is big, and when big electric current uses, temperature is lower, and energy loss is less, and the energy content of battery is in hgher efficiency, and battery high rate performance is more preferable.4、
Battery uses ceramic diaphragm high-temperature behavior more preferable.5, insulating trip uses halogen-free flameproof nonmetallic materials, and fire protecting performance is more superior.
6, battery plus-negative plate ear and explosion-proof cap are connected by Laser Welding, weld more reliable, and internal resistance is lower, and consistent performance is more preferable.7, electricity
Pond core both positive and negative polarity is dielectrically separated from box hat, and battery does when assembling in groups, and anti-external short circuit performance is more preferable.
