The present invention discloses a high-temperature accelerated storage test method for a zinc-silver battery, comprising: a step 101 of dividing N zinc-silver batteries into four groups according to high-temperature accelerated storage temperatures and respectively putting the four groups of zinc-silver batteries into constant temperature ovens at the temperatures of 40 DEG C, 50 DEG C, 60DEG C, and 70 DEG C; taking out the zinc-silver batteries for performing discharge at intervals of time T, and drawing a diagram about an average discharge capacity of the zinc-silver batteries changing over time at different storage temperatures; calculating an attenuation rate of the average discharge capacity of the zinc-silver batteries at different storage temperatures; a step 102 of taking the attenuation rate of the average discharge capacity of the zinc-silver batteries at different storage temperatures as a life characteristic K to fit a linear function about logarithm of the life characteristic K relative to reciprocal of thermodynamic temperature; a step 103 of calculating an accelerated factor of different storage temperatures of the zinc-silver batteries relative to a normal temperature; and a step 104 of calculating high-temperature accelerated storage time corresponding to normal-temperature storage time, and simulating the state of the zinc-silver battery after normal-temperature long-time storage through high-temperature short-time storage of the zinc-silver battery.
