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.
Lithium battery pure aluminum spacer, made of high - purity aluminum, have good thermal conductivity, corrosion resistance and mechanical strength. They fill gaps, ensure flatness, and are used in lithium - ion batteries for functions like heat dissipation and component connection, enhancing battery performance and safety.
