During production and processing, it is only necessary to wrap the upper surface of the positive and negative plate The processing can be completed by laying an AGM partition, and the process is very simple.

3. In this lead-acid battery grid assembly with high heat storage performance, the edge sealing on both sides of the bag-type AGM separator is composed of a lower closed part and an upper open part, and the open part accounts for 1% of the total length of the two sides. /5 to 1/4 length, considering the dismantling and secondary utilization of the AGM separator in the later stage, the edge banding on both sides is made into an open structure at the upper part, which is convenient for the removal of the plate in the later stage.

4. For the lead-acid battery grid assembly with high heat storage performance, the edges of both sides of the bag-type AGM separator are bonded or sewed with acid-resistant film; the material of the acid-resistant film is PP film and glass fiber cloth Acid-resistant cloth compounded with PTFE resin; acid-resistant sewing thread or acid-resistant glue bonding to improve the overall anti-corrosion performance of the AGM partition and prolong its service life.

5. The structure design of the utility model is scientific and reasonable, which can reduce the overheating of the positive and negative plates during high-current discharge, and is easy to process without increasing the overall size of the battery. It is a highly innovative battery with high heat storage performance. Lead acid battery grid assembly.
