They established a model for uneven heat production of batteries, revealing that higher rates result in increased temperature distribution unevenness within the battery. This, in turn, leads to uneven lithium plating on the surface of the anode, accelerating battery aging.
Unlike the thermal runaway behavior changes observed in batteries aged under high temperatures—where aged batteries exhibit delayed thermal runaway compared to new batteries—those aged under low temperatures show worse thermal runaway behavior, with more severe temperature rises and mass loss .
On a large scale, recycling could also help relieve the long-term supply insecurity – physically and geopolitically – of critical battery minerals. Lithium-ion battery recyclers source materials from two main streams: defective scrap material from battery manufacturers, and so-called “dead” batteries, mostly collected from workplaces.
They found that the temperature difference between the cathode and anode surfaces during charging and discharging increases after storage. Additionally, the electrolyte tends to deposit downward during re-storage, exacerbating battery aging.
Lithium-ion battery aging primarily arises from a series of physicochemical reactions occurring within the battery. This section provides a detailed analysis of the aging side reactions within the battery, focusing on its main components.
