1. Introduction. The lithium-ion battery (LiB) is a common type of rechargeable battery due to its high energy density, long life cycle, and low self-discharge rate [] is widely used in various fields such as portable electronic devices, industrial energy storage systems, and electric transportation [2,3].Generally, the acceptable operating temperature region for LiBs is −20°C–60°C
