Under overcharge conditions, the interior temperature of polymer lithium-ion rechargeable batteries will rapidly increase. Such batteries are adopted in electric vehicles that require rapid charging and discharging, and this process causes rapid heating, raising safety issues, including thermal runaway and even potential explosion. Hence, flexible micro two-in-one sensors for the in-situ monitoring of temperature and voltage in polymer lithium-ion rechargeable batteries must be developed. Traditional instruments are too large to be used to measure temperature and voltage inside polymer lithium-ion rechargeable batteries. In this work, the micro-electro-mechanical system (MEMS) is utilized to develop flexible micro two-in-one sensors for the in-situ monitoring of temperature and voltage within a lithium-ion rechargeable battery.
