What does the discharge of lithium battery 70c mean?

The discharge of lithium battery 70c means that the discharge rate of the battery is as high as 70C.

The discharge c number of lithium battery is the discharge c rate of the battery, which is used to represent the charging and discharging current. C represents the symbol of the discharge rate of lithium battery, such as 1C represents the ability of lithium battery to discharge stably at 1 time discharge rate, and so on, such as 2C, 10C, 40C, etc. , representing the maximum current discharge multiple that the lithium battery can discharge stably. The charge-discharge ratio of a lithium battery is equal to the charge-discharge current divided by the rated capacity of the battery. ?

Generally, we call lithium batteries discharged at 1C as standard batteries, those discharged at 2C- 10C as low-rate batteries, and those discharged above 10C as high-rate batteries. The main difference between rate battery and traditional standard battery lies in the manufacturing process. Standard batteries and low-rate batteries are mostly made of wound pole pieces, while the internal pole pieces of high-rate batteries used for emergency start-up power supply are made of laminated technology, which indirectly provides a simple method to distinguish them. The winding process of the battery will be slightly thicker on both sides, and the flatness will be slightly worse, while the lamination process of the lithium battery is quite flat and square. ?
