Progress and Challenges for All-Solid-State Sodium Batteries
A battery combining the Na-β″-Al 2 O 3 with a solid-gel NaTi 2 (PO 4) 3 composite layer as the cathode and sodium metal as the anode showed a capacity loss of 9% (initial capacity of 121.2 mA h g −1) over 50 cycles at 0.1C; moreover, they inferred that the interfacial incompatibility between the sodium anode and the ceramic electrolyte may ...
