The Rechargeable battery using uranium as an active material

Ouchi, Kazuki  ; Ueno, Katsuhiro; Watanabe, Masayuki   

We first demonstrate a nonaqueous rechargeable battery using uranium and iron as active materials. This uranium-iron battery achieves an open-circuit voltage of approximately 1.3 V, exhibits stable cycling performance, and delivers a good Coulombic efficiency of 862%. These characteristics suggest a promising avenue for utilizing depleted uranium in innovative applications.
