Prototype Characteristics

Charge / discharge test

Evaluate the charge / discharge characteristics of prototype batteries and commercially available batteries (initial capacity, rate characteristics, input / output characteristics)

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.
