What does 70c discharge of lithium battery mean?

Introduction What does 70c lithium battery discharge mean? 70c lithium battery discharge means the battery discharge rate can reach 70C. The lithium battery discharge C number is the C discharge rate of the battery, which is used to indicate the maximum charge and dis

What does 70c discharge of lithium battery mean?

70°C discharge of lithium battery means the battery discharge rate can reach 70°C.

The discharge C number of the lithium battery is the discharge rate C of the battery, which is used to indicate the size of the charge and discharge current. C represents the symbol for the discharge rate of the lithium battery. For example, 1C represents the lithium battery's ability to discharge stably at 1 times the discharge rate. By analogy, other symbols such as 2C, 10C, 40C, etc. Lithium represents the maximum current discharge multiple that the battery can discharge stably. The charge and discharge rate of the lithium battery is equal to the charge and discharge current divided by the rated capacity of the battery. ?

Generally, we call lithium batteries discharged to 1C as standard batteries, those discharged to 2C-10C as lithium batteries.ible flow and those discharged at more than 10C from high flow batteries. The main difference between high-rate batteries and traditional standard batteries is the difference in manufacturing processes. Standard batteries and low-rate batteries are mainly made by the pole piece winding process, while high-rate batteries used for emergency starting power supply have it. internal pole pieces. The manufacturing process of rolling also indirectly provides a simple method of identification. The battery produced by the winding process will be slightly thicker on both sides and the flatness is slightly worse, while the multi-rate lithium battery produced by rolling. the process is quite flat and square. ?

Hello, may I ask what is the general high rate discharge efficiency of lithium batteries? Discharge efficiencyHigh rate rge of lithium batteries is typically 99.8%. According to the information released by Juda Lithium Battery, the size of charging and discharging current is generally expressed by charging and discharging rate = charging and discharging current/rated capacity; a capacity of 100 Ah discharges with 20 A, its discharge rate is 0.2 C. The discharge rate of the battery C, 1C, 2C, 0.2C is the discharge rate of the battery: a measure of the discharge speed. Charging and discharging efficiency is also related to C. Under 0.2 C conditions, the charging and discharging efficiency of lithium-ion polymer batteries is expected to be 99.8%.
