Abstract

We report a battery made from a single material using Li_1.5Cr_0.5Ti_1.5(PO₄)₃ as the anode, cathode and electrolyte. A high rate capability at room temperature and very low-temperature operation (233 K) were possible as a result of the superior ionic conductivity and low interfacial resistance obtained from the single-phase cell design.
