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.
What happens if you charge a lithium battery at high temperatures?
Charging lithium batteries at extreme temperatures can harm their health and performance. At low temperatures, charging efficiency decreases, leading to slower charging times and reduced capacity. High temperatures during charging can cause the battery to overheat, leading to thermal runaway and safety hazards.
