Abstract
A battery crushing method includes cooling a battery, which is kept in a gaseous environment, to an electric discharge temperature ranging from −60° C. to 0° C.; and after cooling, crushing the battery at a crushing temperature to form a plurality of crushed particles. The crushing temperature is not greater than a temperature ranging from −10° C. to 10° C.
Claims13
A battery crushing method, comprising:
- cooling a battery, which is kept in a gaseous environment, to an electric discharge temperature ranging from −60° C. to 0° C.;
- and
- after cooling, crushing the battery at a crushing temperature to form a plurality of crushed particles, the crushing temperature being not greater than a temperature ranging from −10° C. to 10° C.
A battery crushing system for processing a battery, comprising:
- a cryogenic electric discharge device including a cooling unit, and a sensing unit that is in signal connection with said cooling unit, said cooling unit having a cooling chamber for accommodation of the battery, and a temperature controller for controlling a chamber temperature in said cooling chamber to thereby cool the battery that is kept in a gaseous environment inside said cooling chamber, said sensing unit being configured to sense the chamber temperature in said cooling chamber to thereby generate a temperature sensing signal, said temperature controller being configured to adjust the chamber temperature in said cooling chamber according to the temperature sensing signal that is received from said sensing unit through the signal connection therebetween;
- a conveying device disposed downstream of said cooling unit for conveying the battery from said cooling unit;
- and
- a crushing device disposed downstream of said conveying device, and including a crushing unit and a temperature control unit, said crushing unit having a container for receiving the battery that is conveyed from said cooling unit by said conveying device, and a crushing member for crushing the battery into a plurality of crushed particles, said temperature control unit being disposed in proximity to said container for adjusting an internal temperature of said container.
