A single-phase all-solid-state lithium battery based on Li1.5Cr0.5Ti1.5(PO4)3 for high rate capability and low temperature operation

We report a battery made from a single material using Li1.5Cr0.5Ti1.5(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.
