In view of deficiency of the test methods of electrical performance parameters of long-circulating solid-state batteries,through the verification of weight-specific energy,2 C discharge capacity retention rate,cycle life,low temperature discharge capacity and high temperature discharge capacity,the changes of key electrical performance parameters such as weight specific energy and capacity retention rate were analyzed.And the test methods for electrical performance parameters of long-circulating solid-state batteries is established,which fills the lack of test method and meets the requirements of application development.
