Research progress on rolling technology of lithium-ion battery electrodes

Lithium-ion power batteries are the heart of new energy vehicles. The key performance and safety of lithium batteries are directly determined by the consistency of rolling thickness, compaction density and peel strength of electrodes, which are the core components of lithium-ion power batteries. For the rolling technology and equipment of lithium battery electrodes, the research status and achievements of domestic and foreign scholars in recent years on new rolling technology, rolling effects on porosity and electrochemical properties, theoretical models of rolling process and rolling equipment were reviewed and summarized. The outlook of electrodes rolling process theoretical research and intelligentization of rolling equipment and process were forecasted based on the future demand of lithium battery industry and the development status of electrode preparation industry.
