Enabling zinc-air batteries at low temperatures is drawing increasing attention, yet the low-temperature working feasibility of zinc-air batteries with noble-metal-free electrocatalysts remains indistinct. In this contribution, the low-temperature performances of zinc-air batteries with noble-metal-free electrocatalysts are comprehensively investigated. Armed with a representative noble-metal-free bifunctional oxygen electrocatalyst, the zinc-air batteries demonstrate satisfactory yet relatively declined performance at low temperatures, compared with that at room temperatures. The reduced electrolyte conductivity is identified as one of the limiting factors for the reduced low-temperature performances. Furthermore, electrolyte engineering via regulating the solvation structure is performed on the zinc-air batteries with noble-metal-free electrocatalysts, where a promoted low-temperature performance is achieved. This work reveals the compatibility between noble-metal-free electrocatalysts and low-temperature feasibility/low-temperature performance enhancement strategies for zinc-air batteries and affords new opportunities to satisfy low-cost and efficient energy storage at harsh working conditions.
