| Outline of Final Research Achievements |
In order to improve the energy density of the storage battery, if lithium metal can be used for the negative electrode, a significant improvement in energy density can be expected. However, it is a crucial problem that lithium is electrodeposited in the form of dendrite during charging, resulting in short-circuiting and loss of lithium. Therefore, in this research, we proposed a rocking-chair-type dual-salt battery which makes both magnesium ion and lithium ion charge carriers. In this rocking-chair-type dual-salt storage battery, it is expected that drastic improvement in energy density can be achieved by using the Mg-Li alloy negative electrode that is capable of suppressing dendrite electrodeposition.
