Applications:
1). CMC in alkaline battery is used as protective agglomerating agent of negative pole.
2). CMC is possibly used as binding agent for positive pole and negative pole of high performance battery.
3). Also can be applied as binding agent for nickel-cadmium battery, nickel-metal hydride battery used in electronic tools.
4). Its main advantages are strong adhesion, easy to operate, not influence its conductivity.
