The functional film mainly made of polyethylene (PE) plays a key role in physically isolating the positive and negative electrodes to prevent short circuits.
The coating forms a dense barrier through high-temperature sintering, enabling the separator to withstand temperatures above 1800℃. This effectively blocks heat conduction during thermal runaway.
AOT-MSK-PSC-MM2020 is a precise sheet-to-sheet slot die coater with a 200 mm coating width and the super flat marble vacuum chunk is used for thin film coating with high uniformity. This coater is designed for ultrathin perovskite layer coating with diluted precursor solutions.
The AOT-YCSM-20XZ automatic double-sided spot welder is suitable for spot welding of individual battery cells in series and parallel connection before assembly in PACK factories. The electrical control part of the spot welder adopts a modular design, featuring high integration, good versatility, and easy maintenance
