Abstract:Improve the fast charging ability of li-ion battery is one of the important development directions of battery industry. However, fast charging battery often suffers from capacity and power performance degradation. Development of fast charging battery involving multiscale problem, needed to take into full consideration from atomic to battery level. In this paper, some of the key elements of developing fast charging battery were summarized based on the existing literatures. These elements include improving fast charging ability of batteries, improving the migration rate of lithium ions in the cathode material, speeding up the insertion rate of lithium ions into the anode material, increasing the ion conductivity of electrolyte, choosing the fast charge separator, enhancing the conductivity of ions and electrons in the electrode, and optimizing charge protocols.
Keywords:lithium-ion battery  fast charging  research progress
