Therefore, the spring constraint scheme can maximize the positive effect of external pressure on lithium-ion batteries by maintaining a relatively stable external pressure. The results presented in this paper have a certain guiding significance for the design of the battery pack. 1. INTRODUCTION
Reduced ionic pore resistance gets dominant in compressed cells at high C-rates. Compressibility is strongly dependent on the number of layers. Uncompressed Li-ion batteries tend to Li deposition. An optimum compressive pressure exists that extend the battery life. Cyclable lithium loss is reduced at the optimum pressure.
