I. Why are membrane coating materials needed? In lithium-ion batteries, the membrane’s function is to isolate the positive and negative electrodes while allowing lithium ions to pass through. However, traditional polyolefin membranes (PE/PP) have significant problems: · Poor high-temperature resistance (shrinkage begins around 130℃) → prone to thermal runaway · Poor wettability → weak electrolyte […]

In natural gas purification processes, COS (carbonyl sulfide), a common organic sulfide, is widely present in natural gas, LNG, and refining gases. Due to its stable chemical properties and difficulty in direct removal, COS not only affects the performance of downstream catalysts but also corrodes equipment and can even lead to excessive sulfur content in […]

In the field of industrial gas processing, the presence of moisture not only compromises product quality but can also lead to equipment corrosion, catalyst deactivation, and increased system energy consumption. Consequently, selecting an efficient and stable drying medium is of paramount importance. Activated alumina desiccant, distinguished by its exceptional adsorption properties and regenerative capabilities, stands […]
