Abstract

The invention provides a flame-retardant battery system which is simple in structure, easy to prepare and good in flame retardance. The system comprises a battery, a box body, cooling liquid, battery tabs, a connector, a pressure relief valve, a solenoid valve, cooling fins and a master positive / negative interface, wherein the battery, the battery tabs and the connector are connected with each other and immersed in the cooling liquid; and the cooling liquid comprises a pure fluorocarbon compound, a mixed solution of a fluorocarbon compound and transformer oil, or a mixed solution of a fluorocarbon compound and silicone oil, and the fluorocarbon compound has a boiling point of more than 80 DEG C and is free of chlorine.

Description

technical field [0001] The invention belongs to the technical field of battery system preparation, and in particular relates to a flame-retardant battery system. Background technique [0002] Due to the increasingly frequent use of electric energy and the higher and higher requirements for battery life of electrical devices, large-capacity batteries have been widely used. However, the difficulty of flame retardancy of this type of battery has also attracted people's attention, and a variety of flame-retardant battery systems have been developed. [0003] CN 101369640 A provides a flame-retardant battery, which solves the problem of preventing battery explosion. However, the battery of this patent is not suitable for the explosion-proof problem of large-capacity batteries, and its complex structure and manufacturing process limit its large-scale application. [0004] CN 104167567 A provides a preparation process for a flame-retardant battery, and the battery obtained under ...
