Battery electrodes made of dry powders with adhesive are attracting people's attention in battery research due to their possible high energy density.
The flexible electrolyte has become a popular project due to battery safety issues.
MTI provides the equipment below to make the research possible at a lab scale and at affordable costs.
Please click the pictures in the table below to see the details for each product.

Application Notes |
| Dry powder mixing with adhesive |
  
Jet Milling Planetary Centrifugal Mixing High Dispersing
|
Uniform mixing of dry powder and the polymer binder
is critical for dry film preparation |
| Dry Electrode Film Forming |
   
Hot Plate Press Roll to Roll Hot Rolled Hot extrusion Pre-mold+ Hot Rolling |
The well-mixed powder would be added into the tape hot rolled with digital pressure display and digital pressure adjustment to form a solid electrode. For a small sample, use a flat hot press to prepare a film
|
| Hot Rolling |
  
Hot Rolling Press Sheet rolling Roll to Roll Hot Rolling Press |
The dry electrode requires further hot rolling
to increase density and form a thinner sheet |
Surface cleaning and etching by
Plasma |
  |
For the aluminum and copper foil/substrate,
it needs to be coated with a conductive adhesive layer. |
| Lamination Rolling |
Dual Side Laminating Machine |
The film can be laminated on the current collector (foil)
by the roll to roll lamination machine,
and form two side coated dry electrode |
