Development of Future Battery Chemistry
Battery prototype evaluation equipment for coating liquid (slurry preparation) – continuous coating (desktop coating) – press-cell assembly-charge / discharge characteristic evaluation is also available.
Supplement : You can try the following three methods for the stirring device for adjusting the coating liquid. Others will be dealt with after consultation.
- Rotational revolution type
- Planetary type
- Thin film high-speed swivel type (Primix Corporation)
Our operator will operate and operate each equipment according to your instructions.

Cycle Life Characteristics
Durability is evaluated by charge / discharge cycle tests of prototype batteries and commercially available batteries. Durability evaluation by repeating charging and discharging and changing capacity
- You can perform cycle tests of laminated laminated cells using the materials supplied by the customer.
- You can evaluate by replacing a part of the cell member with our material.

AC impedance evaluation
AC impedance measurement is performed to evaluate basic battery characteristics and analyze the cause of deterioration.
