| Summary: | Purpose – The internal resistance of a single power lithium-ion battery is an important representation of its power characteristics. When the current flows through a single battery with high internal resistance, the amount of heat generated is relatively large, resulting in accelerated deterioration of the single power battery, further increasing the internal resistance, accelerating the deterioration of the single power battery with high internal resistance, and seriously affecting the endurance and safety performance of new energy vehicles. Therefore, this paper studies the mechanism and improvement plan of low internal resistance consistency of a single battery. Design/methodology/approach – Addressing the issue of high internal resistance in lithium-ion batteries at the production site, we employed a full-factor analysis using a quality tree approach to examine raw materials, production equipment and processes. This enabled us to identify the root causes and subsequently improve the internal resistance of lithium-ion batteries through upgrades in equipment and process optimization. Findings – Through the analysis and improvement of the internal resistance of power lithium-ion batteries, a comprehensive understanding of the internal resistance of the power lithium-ion battery has a comprehensive understanding of the influencing factors of power lithium-ion batteries. The use of power lithium-ion batteries on new energy vehicles has played a supporting role.
