Liquid lithium ion battery.portable solar power generator

　　The rechargeable lithium -ion battery is the most widely used battery in modern digital products such as mobile phones and laptops. Therefore, there are protective components or protection circuits on the battery to prevent expensive battery damage. The charging requirements of lithium -ion batteries are high. To ensure that the termination voltage accuracy is within ± 1%, major semiconductor device factories have developed ICs for charging multiple lithium -ion batteries to ensure safe, reliable, and rapid charging.

　　The mainstream mobile phone is equipped with a lithium -ion battery. The correct use of lithium ion batteries is very important for extending battery life. According to the requirements of different electronic products, it can be made into a flat -shaped square, cylindrical, rectangular and buckle, and has a battery pack composed of several batteries and connecting together. The rated voltage of a lithium -ion battery is usually 3.7V because the material changes are usually 3.2V. The termination voltage at full charging is generally 4.2V and lithium iron phosphate 3.65V. The termination voltage of the lithium -ion battery is 2.75V ～ 3.0V (the battery plant gives a working voltage range or gives a stop discharge voltage. Each parameter is slightly different, generally 3.0V, and the phosphorus iron is 2.5V). It is less than 2.5V (lithium iron phosphate 2.0V) continues to discharge, and it will damage the battery.
