The invention discloses a rapid high-temperature curing drying process of a lead-acid storage battery unformed electrode plate. The process comprises the following steps of curing the unformed electrode plate which is coated with lead plaste in a curing chamber with the humidity of 95 to 99 percent and the temperature of 47 to 50 DEG C for 3 to 5h; increasing the indoor temperature in the curing chamber to 83 to 86 DEG C within 2 to 4h, curing the unformed electrode plate for 15 to 20h under the condition that the indoor temperature is 83 to 86 DEG C and the humidity is 97 to 99 percent, and reducing the temperature inside the curing chamber to 60 to 65 DEG C, and reducing the humidity to 90 to 95 percent; maintaining the temperature in the curing chamber to 60 to 65 DEG C, reducing the humidity to 80 to 85 percent, and curing the unformed electrode plate for 5 to 7h; increasing the temperature in the curing chamber to 86 to 88 DEG C within 2 to 4h, and reducing the humidity to 0 to 10 percent; maintaining the temperature in the curing chamber to 86 to 88 DEG C, controlling the humidity to 0, and drying the unformed electrode plate for 10 to 12h under the high temperature. The process is short in curing drying time, the curing drying time is shortened for 20h compared with that in an existing process, not only can an existing curing drying device be utilized, but also the curing drying time can be shortened under the condition that the investment is not increased, the production efficiency is improved, and the service life of the storage battery is prolonged.
