Problems that can be solved
Swelling and shrinking of the negative electrode active material during charge and discharge lead to the occurrence of electrode peeling and isolated particles. ⇒ The swelling control of the active material is important for the improvement of the cycle characteristics.
Suppresses the negative electrode swelling during charge and discharge, greatly improving the cycle characteristics of LiB.
Comparison of electrode swelling and cycle characteristics
before and after charge and discharge cycle
Suppresses the negative electrode swelling caused by swelling and shrinking of the negative electrode active material during charge and discharge, improving cycle characteristics (capacity retention rate after 500 cycles: approx. 1.5 times).
