Improving the rate capability of lithium-ion batteries is beneficial to the convenience of electric vehicle application. The high-rate charging, however, leads to lithium inventory loss, mechanical effects and even thermal runaway.

Fig. 1 summarized the multiple challenges for fast charging of lithium ion batteries. For example, the potential degradation of material caused by fast charging, mechanisms limiting charging efficiency at low temperatures. The adverse effects of temperature rise induced by fast charging and intensified temperature gradient on battery performance.
When the temperature of the battery reaches a high value, the thermocouple will not work; therefore, the T H will not be recorded after 220.50 °C. The temperature increases at a low rate just before the thermal runaway is induced. After thermal runaway begins (T I = 208 °C), the temperature increases very quickly.
By raising the voltage at the charge/discharge plateau, the energy density of the battery is increased. However, this causes transition metal dissolution, irreversible phase changes of the cathode active material, and parasitic electrolyte oxidation reactions.
Additionally, high charging voltages can hasten the breakdown of solid electrolyte interface (SEI) , which reduces the reversible capacity and service life, and, in extreme situations, causes safety issues with lithium-ion batteries.
