| Research Abstract |
We focused our research on the storage and life cycle performance of the lithium-ion secondary cells for the long term operations. Furthermore, we measured the impedance and calculated the activation energy. We especially prepared the lithium-ion secondary cells with and without additives to control the SEI layer, and tried to evaluate the effect of the additives to the trend of the activation energy to assure the safety.
