Fully-Reversible Solid-State Li-Ion Rechargeable Battery Composed of Positive and Negative Electrodes with the Same Active Material

In this paper, we found out for the first time that the fully-reversible solid-state Li-ion rechargeable battery composed of positive and negative electrodes with the same active material Li₂Mn₂O₄.  It should be noted that the present novel reversible operation is observed because of the solid-state Li-ion battery.  It will be expected that such a reversible battery is expected to be refreshed on the backward stage, when the RiLiB battery has run down at last on the forward stage,
