What is the difference between using large current and small current to separate lithium batteries?

Introduction What is the difference between using a large current and a small current to divide the capacity of a lithium battery? I know that it is generally charged and discharged according to 0.2 C. For battery capacity division, the difference between using large

What is the difference between using large current and small current to separate lithium batteries?

For battery capacity division, the differences between using high current and low current are as follows

1. Large current capacity division, capacity division time is short, small current capacity division time is long, now many manufacturers all use 0.5-1c to divide capacity

Theoretically, it takes 5 hours to divide the capacity to 0.2c, and 1c only takes 1 hour. Time is inversely proportional to current size<. /p>

2 Generally speaking, the capacitance divided by a small current is greater than the capacitance divided by 1c, but the difference should be about 0.5-2%.

If the difference is big, it means the quality of the battery itself. This aspect presents some problems.

Training: generally refers to the implementation of a series of process measures on the initially charged battery to stabilize itsperformance, including low current charging and discharging. , standing and standing at a constant temperature below 60°C, etc. , there are also charging and discharging procedures that specifically refer to the first charge to complete the activation of the battery electrodes.

Capacity classification: A simple understanding is capacity sorting and performance monitoring and ranking.
