Abstract

The invention discloses a method for continuously reducing the temperature rise of a storage battery during use, and relates to the technical field related to the shedding of battery active materials; There is a gap of 0.3-1cm in the battery case, and liquid nitrogen is filled in the gap; the present invention continuously cools the battery in use to solve the problem that the heat generated by the battery in use cannot be conducted in time, resulting in high internal temperature of the battery. Phenomena such as active material falling off occur, and the method of the present invention is simple, convenient, and low in input cost, and combined with the prepared heat-transferable material, the temperature of the storage battery is cooled, and the service life of the active material and the storage battery is prolonged.

Description

Technical field: [0001] The invention relates to the technical field related to the shedding of battery active substances, in particular to a method for continuously reducing the temperature rise of a storage battery during use. Background technique: [0002] Lead-acid batteries, lead-acid batteries have stable working voltage, wide range of operating temperature and operating current, can charge and discharge hundreds of cycles, good storage performance (especially suitable for dry charging storage), and low cost, so they are widely used. Its size and weight have not been effectively improved, so it is most commonly used in automobiles and motorcycles. The biggest improvement of the lead-acid battery is the recent use of high-efficiency oxygen recombination technology to complete water regeneration, so as to achieve the purpose of being completely sealed without adding water, and the resulting "water-free battery" has a lifespan of up to 4 years. [0003] The composition o...
