Hello, may I ask what is the general high rate discharge efficiency of lithium batteries? The high-rate discharge efficiency of lithium batteries is generally 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%.
70C discharge of lithium battery means the battery discharge rate can reach 70C.
The discharge C number of the blithium 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 standard batteries, those discharged to 2C-10C low-rate batteries, and those discharged above 10C high-rate batteries. The main difference between high flow batteries and traditional standard batterieses lies in the difference in the 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. ?
