Lithium-ion battery (LIB), a tremendously successful technology for energy storage, has become the dominant power source in applications ranging from consumer electronics to electric vehicles. There is an increasing desire for stable storage and utilization of electrical energy under extreme conditions such as cold-climate, aerospace exploration, and subsea operations. These applications feature highly diverse and varying working environments with overcharge/discharge, high pressure, external forces and, often most critical, high/low temperature. For example, LIBs lose most of their capacity, power, and cycle life when operated below ambient temperature. Therefore, it is crucial to gain more insights into the mechanisms causing the LIB performance degradation upon exposure to low-temperature conditions, which could aid engineering of active materials, electrode structure, and charge/discharge protocols.
