Charging a lithium battery generates hea t, and there are several reasons why this might happen more intensely during charging. High Charging Current: Fast charging methods, while convenient, push a lot of current into the battery quickly, generating heat.
The new batteries got really hot - too hot to touch. What causes this to happen? Batteries can heat up if you have a short circuit. Instead of the electricity going through a circuit where it is used up in various ways or resisted, it just goes straight through the battery, and is then conducted back around into the battery again.

To reduce the energy consumption of batteries during the heating process of EVs, researchers have proposed burner heating methods that utilize alternative energy sources.
For battery modules with relatively high demand for low-temperature heating, a single battery heating method can no longer meet the demand. Therefore, in recent years, most people have begun to study hybrid heating methods so that a battery can warm up rapidly while also improving temperature uniformity and safety.
Resistance to Charge Transfer: this resistance can also generate heat during charge and discharge processes, Occurring at the interface between the electrolyte solution and the electrode materials. Electric Resistance within Battery Components: This resistance is intrinsic to various battery parts and contributes to heat generation.
Dave - Charging batteries isn't 100% efficient and similarly, discharging batteries isn't 100% efficient. The way electronic engineers like to think about it is that the battery has a resistance, so if you draw a current from that battery then you're pushing that current through a certain resistance and so, it will heat up.
