Traditional lithium-ion battery electrodes are coated by wet method, which is the active material, conductive agent and binder mixed in solvent, and then coating on the current collector foil by slot die coating or transfer coating machine. But this method has the problem of long drying time and solvent recovery, which greatly increases the production cost and the complexity of the process.
TOB New Energy dry electrode technology is the technology of mixing PTFE binder, active material and conductive agent at high speed, rolling through roller press machine, and then laminating with the current collector foil coated with conductive adhesive to produce dry electrode sheet. This process does not use a lot of organic solvents, which is beneficial to extend the capacity and cycle life of the battery.
There are three main steps to go from dry electrode powder to dry electrode film
1. Dry electrode powder press into thin semi-finisheddry electrode film.
2. Semi-finished dry electrode film rolling to required thickness.
3.1 Conductive adhesive coating on current collector foil.
3.2 Semi-finished dry electrode film and current collector foillaminating.
