The sealing method comprises the following steps that S1, acid-resistant high-temperature lubricating grease is smeared, a telescopic sealing ring is pressed into a pole hole from bottom to top, and a gap is formed between the top of an outer flanging and the bottom of the pole hole; s2, putting the copper core pole and the positive and negative pole plates into a mold, and welding to form a positive and negative pole group; s3, loading the positive and negative electrode groups into a battery jar, correcting, and smearing acid-resistant and high-temperature-resistant lubricating grease on the inner hole surface of the telescopic sealing ring; and S4, the battery cover body pressed into the telescopic sealing ring is grabbed by a heat sealing machine for alignment, and is pressed tightly after hot melting, so that the telescopic sealing ring is in close fit with the copper core pole, and the battery cover and the hot melting part of the battery jar are sealed together. In the using process of the storage batt
