Lithium-ion secondary batteries are commonly used in electric vehicles, smart phones, personal digital assistants (PDA), notebooks and electric cars. These lithium-ion secondary batteries must charge and discharge rapidly, causing the interior temperature to rise quickly, raising a safety issue. Over-charging results in an unstable voltage and current, causing potential safety problems, such as thermal runaways and explosions. Thus, a micro flexible temperature sensor for the in in-situ monitoring of temperature inside a lithium-ion secondary battery must be developed. In this work, flexible micro temperature sensors were integrated into a lithium-ion secondary battery using the micro-electro-mechanical systems (MEMS) process for monitoring temperature in situ.
锂离子二次电池广泛应用于电动汽车、智能手机、个人数字助理 (PDA)、笔记本电脑和电动汽车中。这些锂离子二次电池必须快速充电和放电，导致内部温度迅速升高，引发安全问题。过充会导致电压和电流不稳定，从而产生潜在的安全问题，如热失控和爆炸。因此，必须开发一种用于锂离子二次电池内部温度原位监测的微型柔性温度传感器。在这项工作中，使用微机电系统 (MEMS) 工艺将柔性微温度传感器集成到锂离子二次电池中，用于原位监测温度。
