Abstract

The invention discloses a method for continuously reducing temperature rise in a using process of an accumulator, and relates to the related technical field of battery active substance falling. The method comprises the following steps: additionally installing a layer of a protecting layer housing on the periphery of an accumulator housing, and reserving 0.3-1 cm of a gap between the protecting layer housing and the accumulator housing, wherein the gap is filled with liquid nitrogen. The method is capable of, through continuously reducing a temperature of the accumulator in use, solving a problem that generated heat of the accumulator in use cannot be conducted in time so that phenomena, such as active substance falling, are caused by a high internal temperature of the accumulator, the method is simple, convenient, and low in investment cost, and capable of, through combining a prepared heat-transfer material, reducing the temperature of the accumulator, and prolonging the service lifeof the active substance and the accumulator.

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...
