ゼオライトナノ粒子によるリチウムイオン二次電池の劣化抑制

抄録

In order to improve the performance of lithium-ion batteries, nano-sized zeolite was added to the batteries and its supression deterioration effect was confirmed. The nano-sized zeolite was shown to suppress SEI growth on the anode surface by SEM and TEM observations, and to suppress the increase in internal resistance by AC impedance measurements. The nano-sized zeolite not only absorbs water and gases generated by the decomposition of the electrolyte, but also suppresses the swelling of the cell, thus contributing significantly to the safety of the cell.
