However, high-power charging may negatively affect the durability and safety of lithium batteries because of increased heat generation, capacity fading, and lithium plating, which can induce the risk of battery thermal runaway.
Connecting a higher-current power supply to a lithium-ion charger will damage the battery. Why? I am not asking how the battery gets damaged, because that answer is straightfoward. What I am asking is why lithium-ion chargers allow batteries to be damaged by excessive charge current in the first place.
The influence on battery from high charge and discharge rates are analyzed. High discharge rate behaves impact on both electrodes while charge mainly on anode. To date, the widespread utilization of lithium-ion batteries (LIBs) has created a pressing demand for fast-charging and high-power supply capabilities.
Rapid discharge can indeed be harmful if it leads to excessive heat buildup. However, lithium-ion batteries are designed to handle certain levels of immediate dismissal without damage. For instance, electric vehicles, which use large lithium-ion battery packs, can accelerate, requiring high discharge rates.
Temperature extremes can indeed affect lithium-ion batteries. Charging batteries at temperatures below 0°C (32°F) can cause permanent plating of metallic lithium on the anode, while high temperatures during charging can degrade the battery more rapidly.
Excessive charge rates can end up with pure metallic lithium 'where it ought not be' with capacity effects at best and vent with flame at worst. Among other things LiIon battery lifetimes are due to the structure being mechanically flexed as Li is moved around the cell.
