| Abstract: |
| During the comprehensive recovery of waste power ternary lithium batteries, due to the residual voltage of the waste power batteries, in the subsequent dismantling and crushing process, it is easy to generate a large amount of heat due to the short circuit of the battery, and even dangerous situations such as explosion may occur, leading to accidents. The article explores the chemical solution discharge test of different concentrations of waste power ternary lithium batteries and the influence of ambient temperature on discharge efficiency and provides effective data support for more efficient release of electrical energy. The results show that the use of solutions that are weaker in metal than aluminum such as copper sulfate and zinc sulfate can effectively shorten the discharge time. At the same time, lower ambient temperature will greatly increase the discharge time, which points out the direction for the construction of industrial discharge production lines |
