Development status of power lithium-ion batteries in China

The advantages of high energy density and long life of power lithium battery make it a candidate for new energy electric car battery with practical value, but in the production process of power lithium-ion battery, its correlation goals (safety, capacity, internal resistance, cycle life, etc.) are contradictory, so battery production needs to take into account the functions of electrode data, electrolyte and barrier under the coordination of installation skills, battery system group skills and management skills, so that the correlation goal of the battery exerts synergistic effect.
