Scientists design low-cost sodium-ion battery with cheap electrode materials

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.An international research team has designed a sodium-ion battery (SIB) storage system based on a P2-type cathode material known as Na0.67Mn0.33Ni0.33Fe0.33O2 and an anode relying on a hard carbon material fabricated from lavender ...
