The invention provides a lithium-air battery test mould comprising a sealed container, an intake mechanism, an exhaust mechanism, and a plurality of clamping mechanisms. The sealed container is provided with a water absorbing layer at the bottom. The intake mechanism is communicated with the sealed container and used for guiding oxygen into the sealed container; one end of the intake mechanism is located outside the sealed container and the other end extends into the sealed container and to the lower portion thereof. The exhaust mechanism is communicated with the sealed container; one end of the exhaust mechanism is located outside the sealed container and the other end extends into the sealed container and to the upper portion thereof. Each clamping mechanism comprises an electrode shell disposed in the sealed container and used for clamping the positive and negative electrodes of lithium-air batteries, a lead with one end connected to the electrode shell and the other end extending to the outside of the sealed container, and a sealing member arranged on the sealed container and used for allowing the lead to penetrate out of the sealed container and guaranteeing seal. The lithium-air battery test mould is simple in structure and low in cost.
