Abstract：The assembly of coin cell is relatively convenient and easy,and can provide repeatable experimental data,has become the preferred testing method for the performance of battery materials in laboratories.However,the coin cell system uses lithium metal to provide excess lithium source for the electrode,which can mask the side reaction issues in the cell,and it is difficult to accurately evaluate the interaction between the positive and negative electrode materials under actual matching conditions,and also cannot accurately predict their performance in the actual lithium ion full cell.In order to accurately predict the performance of battery materials,the research and development of accurate and highly reproducible preparation methods for full coin cell has certain value.This article mainly uses self-made silicon-based negative electrode materials and commercial positive electrode materials,separators,and electrolytes to study the preparation method of full coin cell,analyzes and summarizes the research results.
