High-rate lithium battery is a high-rate rechargeable battery, which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. Batteries that generally use materials containing lithium as electrodes are representative of modern high-performance batteries.
The high-rate lithium battery has high density and high uniform output voltage. Small self-discharge, good battery, less than 2% per month (recoverable), no memory effect. It does not contain toxic and hazardous substances and is called a green battery.
The charging process of high-rate lithium batteries is divided into two stages: constant current fast charging stage and constant voltage current decreasing stage. In the constant current fast charge stage, the battery voltage gradually rises to the standard voltage of the battery, and then switches to the constant voltage stage under the control chip. The voltage does not rise to ensure that it will not be overcharged, and the current gradually decreases to the battery power level. Set the value, and the final charge is completed. The power statistics chip can sample and calculate the battery power by recording the discharge curve. After repeated use of lithium ion batteries, the discharge curve will change. Although there is no memory effect in lithium ion batteries, improper charging and discharging will affect battery performance.
