The dry electrode process is a new manufacturing process for lithium-ion batteries, which does not use solvents in the electrode manufacturing process. Usually, the positive/negative active substances, conductive agents, and solid binders are directly mixed and sprayed onto the collector, or a self-supporting film is made through different processes and then compounded with the collector. This process does not use a large amount of organic solvents, which is beneficial for extending the capacity and cycle life of the battery.
