The external environment (which controls the temperature, voltage, and electrochemical reactions) is the leading cause of internal disturbances in batteries . Thus, the environment in which the battery operates also plays a significant role in battery safety.
What happens to lithium batteries after mechanical deformation?
The number of active materials that can store lithium ions is reduced, and the capacity loss occurs. Therefore, the electrode gap in Fig. 9 b and Fig. 9 c results in the increase of internal resistance and capacity loss of batteries after mechanical deformation and normal cycling 100 times after mechanical deformation.
How does mechanical deformation affect battery charging?
The conclusions are summarized as follows. The CC charging results of LIBs after mechanical deformation show that with an increase in mechanical deformation, the total charging capacity of a battery decreases, and the charging curve moves to the high voltage region.
