To improve the low-temperature charge-discharge performance of lithium-ion battery, low- temperature experiments of the charge-discharge characteristics of 35 Ah high-power lithium-ion batteries have been conducted, and the wide-line metal film method for heating batteries is presented.
They conducted experiments of the charge–discharge characteristics of 35 Ah high-power lithium-ion batteries at low temperatures. The results showed that the rate of temperature rise is 2.67 °C/min and this method could improve the performance of batteries at low temperatures.
Preheating LIB at low temperatures is the ultimate goal of improving pack capacity and large rate charge/discharge performance. Despite advancements in heating rates, no heating method has emerged that can simultaneously meet the complex requirements of economy, consistency, and safety.
Discharge at low temperature is very unfriendly to battery life. DC preheating technique is more damaging to the battery, AC and pulse preheating techniques can effectively mitigate this damage. It has to be mentioned that the source of AC signals and pulse signals is also a very troublesome thing.
This review will be helpful for improving the thermal safety technology of high-energy density lithium power batteries and the industrialization process of low-temperature heating technology. 2. Effect of low temperature on the performance of power lithium battery
