Battery-Materials Analysis & Evaluation
Characteristic Evaluation
-
Charge-discharge Test
JFE-TEC conducts charge-discharge characteristic evaluation for prototyped batteries or commercially available batteries.
(initial capacity, rate characteristic, input/output characteristic)

Long-Term Cycle Characteristic Evaluation
JFE-TEC conducts durability evaluation through a charge-discharge cycle test for prototyped batteries or commercially available batteries.
Evaluating the durability based on the change in capacity by repeating charge and discharge
Alternating Current Impedance Evaluation
JFE-TEC conducts alternative current impedance measurement for evaluating the basic battery characteristics or analyzing the cause of deterioration.
