What is the difference between a power battery and storage lithium battery?

For power batteries, it is actually a type of storage lithium battery. However, due to the limitations of the size and weight of the car and the acceleration at startup, the power battery has higher performance requirements than the ordinary storage lithium battery, such as the energy density should be as high as possible, the battery charging speed should be faster, and the discharge current should be larger. Wait.For storage lithium battery, most energy storage devices do not need to be moved, so energy storage lithium batteries have no direct requirements for energy density. As for power density, different energy storage scenarios have different requirements.
