Advances in lithium-ion battery technology
Looking ahead, Professor Li intends to further refine her model by incorporating mechanical factors, such as stress generation within the battery components, to explore their potential influence on lithium plating.
“This physics-based guidance is valuable because it enables us to determine the optimal way to adjust the current densities during charging, based on the state of charge and the material properties, to avoid lithium plating,” concluded Professor Li.
Li’s findings were published in the journal ACS Energy Letters.
Meanwhile, the growing demand for electric vehicles has also necessitated improvements in the working of lithium-ion batteries. Therefore, several developments are occurring in this space.
Recently, a team of scientists in the US discovered an imaging technique that allows them to peer inside a working battery.
