Ring an important ring of battery performance.
Existing formation device is most to be all using chemical conversion in parallel it is ensured that the concordance of cell voltage, but simultaneously
Connection chemical conversion haves the shortcomings that between battery, size of current differs, and affects the consistent of battery SEI film.Therefore, design a kind of series connectionization
Become and the formation regime that can voluntarily switch that is melted in parallel is individual settling mode well.
Utility model content
The purpose of this utility model is to provide a kind of novel lithium battery chemical conversion probe bed, and this probe bed can solve the problem that existing
Have not enough present in technology, realize the multiple rows of probe of chemical conversion voluntarily cutting with high frequency between series connection chemical conversion and chemical conversion in parallel
Change.
For achieving the above object, this utility model employs technical scheme below：
