Abstract:
Lithium-ion battery as a reliable energy has been widely used in many devices, however, due to safety problems of lithium-ion battery, its application in the coal field has been largely restricted. The safety issue of application of large-capacity lithium-ion battery in coal mine is a top priority. In order to control the access of lithium-ion battery products in the field, our country has developed new and relevant requirements to carry out stringent production and inspection. The apaper introduces some requirements change for the lithium-ion battery safety performance test, the reasons for the change and assessment for substance are analyzed.
