Abstract:

Potassium-ion batteries (PIBs) have attracted great attention due to the abundance and low cost of potassium resources. However the search for novel electrode materials with high volumetric-capacity for PIBs remains challenging. Here, we report an attractive Cu3P/carbon black anode material for potassium storage through a productive and cheap milling process. The Cu3P particles were homogeneously mixed with the amorphous carbon matrix. The carbon matrix effectively buffers the volume change and improves conductivity; meanwhile the P-C bond formed through the ball milling process can effectively connect the particles and stabilize the structure. Consequently, the fabricated Cu3P/carbon black composite delivered a capacity of 174 mA h g−1at 1 A g−1and remained stable for 300 cycles. The potassium storage mechanism is analysed and revealed byin situsynchrotron X-ray diffraction andex situhigh resolution transmission electron microscopy where a reversible mechanism was observed. The results prove the feasible utilization of Cu3P as a promising anode material for practical application of PIBs.
