1990년대에 개발된 리튬이온 배터리는 그 우수한 성능으로 인해 근래 휴대폰, 노트북 컴퓨터 등의 전원공급수단으로서 널리 사용되어지고 있는 2차 전지이다.Lithium-ion batteries developed in the 1990s are secondary batteries that are widely used as a power supply means for mobile phones and laptop computers.
이러한 리튬이온 배터리는 기존의 니켈계 배터리에 비해 메모리 효과를 가지지 않는다는 점과, 방전시에 (+)극의 리튬이온이 중간의 물질을 지나서 (-)극의 탄소격자속으로 들어 가기 때문에, 극판의 손실이 거의 없어 수명이 길다는 점에서 우수한 성능을 가지고 있다. 따라서 리튬이온 배터리는 인산철, 납방식의 배터리보다 효율이 좋다. 따라서 소형화가 가능하며 전압/전류 출력량이 높다.These lithium ion batteries do not have a memory effect compared to conventional nickel-based batteries, and during discharge, lithium ions of the positive electrode pass through the intermediate material into the carbon grid of the negative electrode. It has excellent performance in terms of long life due to almost no loss of. Therefore, lithium-ion batteries are more efficient than iron phosphate and lead-based batteries. Therefore, miniaturization is possible and the voltage / current output amount is high.

If the temperature is higher than this, the service life of the battery is drastically reduced, and if the temperature is lower than this, the battery efficiency is drastically reduced. In addition, as the load of the battery increases, the temperature of the battery increases, and when the temperature of the surrounding environment is low, the efficiency decreases. Therefore, the temperature measurement and temperature control method of the battery case is important. Lithium-ion batteries are expensive because of their efficiency. Therefore, it is necessary to increase control reliability in battery operation.
