In a recent study published in the Journal of Colloid and Interface Science, researchers analyzed for the first time the fast-charging behavior of micro lithium-ion batteries (LIBs) under ambient and high-temperature conditions.

In this case, the electrochemical test results for 60 mAh LiCoO2/graphite batteries under ambient temperature indicated that the charging rate above 4C (i.e., 4 A for 15 min) resulted in accelerated decay of battery capacity without any noticeable decrease in charging time. However, at a higher temperature of 65 ℃, the charging rate increased to 6C (i.e., 6 A for 10 min).
