Fast charging capability has therefore become one of the key features targeted by battery and EV industries. However, charging at high rates has been shown to accelerate degradation, causing both the capacity and power capability of batteries to deteriorate.
New work on fast-charging batteries has recently been reported by Zhang and colleagues. 93 This article focuses on the extremely fast charging of high energy LIBs by engineering the electrolyte to reduce the charge transfer energy barriers at both the anode and cathode.
By conducting ARC tests on a fast-charged high energy pouch battery, it was found that the self-heating temperature and the thermal runaway triggering temperature drastically reduced for cells subjected to fast charging compared to fresh cells. These effects do, however, seem to be reversible if sufficient rest time is allowed.
To ensure a safe and efficient fast-charging process, it is important to consider the coordination of various components, from materials to devices. Fast charging can generate a lot of heat, especially if the battery is not functioning properly, making safety a critical factor.
