The migration of lithium ions in internal circuit and electrons in external circuit leads to the operation of LIBs. The operation rate, known as charging or discharging rate, is referred as C rate, which is defined as the charging or discharging current divided by the capacity of LIBs.
The disassembly results show that the high-rate pulse charging has no apparent effect on the cathode of lithium batteries, and the cathode morphology has no noticeable change. However, there were obvious lithium-plating areas on the anode of the battery.
With 5 °C as the change step, five different average charge temperatures were set: 16 °C, 21 °C, 26 °C, 30 °C and 35 °C to study the aging process and aging mechanism of lithium batteries under low-temperature charging and high-temperature charging.
Finally, the aging mechanism of lithium batteries under the high-rate pulse charging condition is found. As lithium-ion batteries are prone to lithium plating under high-rate pulse charging, all batteries are disassembled after being charged 10 Ah in order to avoid discharge damaging lithium dendrites on the anode surface.
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
For lithium batteries, it is a high-rate pulse charging condition, and the charging rate may be as high as dozens of C (C is the unit of charging and discharging rates, and a 1C rate corresponds to a current density at which the full capacity of the cell can be charged or discharged in an hour).
