Innovative Rechargeable Battery

Rechargeable batteries are medium that allow non-specialists to experience the concept of energy in real space.

Currently, the most representative rechargeable battery is lithium-ion battery. Lithium-ion batteries, which was the main achievements of the Nobel Prize in Chemistry in 2019, are widely used in small electric devices and automobiles, and play a central role in modern energy technology. On the other hand, lithium-ion batteries have limitations, and the development of energy devices based on new energy conversion principles that exceed them is required.

Energy storage devices that utilize the transfer of multivalent ions and anions between electrodes have the potential to exceed the performance of lithium-ion batteries and are expected to develop, but there are many problems such as ion conduction and reactivity with electrodes. 

In order to overcome these problems, we develop new electrodes and electrolytes, and further analyze the physical properties of materials and reaction mechanisms to establish design guidelines for new power storage devices. For example, fluoride shuttle battery, which is a rechargeable battery using the shuttle of fluoride ions, is a battery system in which an extremely high energy density can be expected. An electrode and an electrolyte of the new battery are developed, and the reaction mechanism in the battery is analyzed.
