In the battery industry, we usually use C-rate to explain the speed of charging and discharge of the battery. So, in this video, Zac will tell you the basic description of the C-rate of lithium battery.
The C-rate represents the amount of energy of battery providing. The higher power, the higher the discharge rate (C-rate). The high-rate battery is divided into a discharge rate and a charge rate, 1C means that the battery is fully charged, and discharged within one hour, 2C is 30 minutes, and so on 10C=6mins, 100C=36 seconds, kind of this idea.
For example, for a 1200 mAh battery, 0.2 C-rating means 240 mA (0.2 mA of the 1200 mAh battery), and 1 C-rating means 1200 mA (1 times rate of the 1200 mAh battery). Normally high discharge rate batteries can be fast-charged. However, since lithium ions are embedded in the negative electrode graphite during charging process, the process of inserting lithium ions into the positive electrode during the discharge process is difficult, so the fast charge ratio is generally lower than the discharge rate.
In order to use in model aircraft, RC vehicle, power tools, racing car, or UAV (Unmanned aerial vehicle), high C-rate battery and lithium battery are usually required because the chemical composition of lithium makes it easier to achieve high-rate and more stable charging and discharge.
