Sep.13, 2022 News Maxell develops the CLB640 coin type high capacity lithium-ion rechargeable battery with a diameter of approx. 6 mm and approx. 1000 charge/discharge cycle characteristics

Sep.13, 2022 Update Data sheet for coin type lithium-ion rechargeable battery “CLB640” added

Features

A unique stacked electrode structure enables power of up to 140mA (CLB2032).

Maxell’s unique stacked structure and electrode structure technology enable Maxell’s CLB2032, which has same size as a coin with a diameter of approximately 20.0mm, to discharge at high load of 140mA.

Discharge capability of CLB2032 is approximately 40 times better

Compared with Maxell’s CR2032, CLB2032 has approximately 40 times greater output discharge current at 60% available capability to meet the demand for long life due to the increased power consumption arising from multi-function equipment.

Excellent cost performance

Superior recharging properties ensure a service life of about 500 charge/discharge cycles under normal usage conditions. The superior cost/performance ratio ensures that lithium-ion batteries are ultimately more economical than primary batteries.


High reliability

Maxell has incorporated unique technologies gained during its development of crimping and electrode coating. The stainless steelbattery body minimizes swelling.

Superior safety

Separator-wrapped positive electrodes prevent to make internal short-circuit. Safety is ensured even if external short-circuit occurs.
