The most widely used communication tool in our daily life is cell phone. The security of mobile phone is also critical. Our company specializes in producing various types of mobile phone li ion batteries, which is more secure and durable. Design of lithium battery for mobile phone
Cell phone battery should be composed of three parts: the electric core, the protection circuit and the shell. The cathode material is lithium cobalt acid.
The standard discharge voltage is 3.7V, the charging cut-off voltage is 4.2V, and the discharge cut-off voltage is 2.75V. The unit of electricity is Wh (Wa Shi), because the standard discharge voltage of cell phone battery is 3.7V, so it can be replaced by mAh (MA). Mobile phone battery is provided with a protective plate. The protection board will automatically power off when the conditions are in place. The A. overcharge protection. That is full of the battery will automatically stop charging. B. discharge protection. That is used in the battery discharge 3.2V will automatically stop. C. short circuit protection is not careful. The battery short-circuit automatically disconnect. That is to say the general rechargeable batteries in about 2-3 hours. After the actual full full has been disconnected. So the charging circuit is of no significance.
