Why Choose Our Battery Separators?
INV engineered to facilitate rapid power delivery and high-rate charging capabilities. As battery technology moves toward faster charging cycles, our separator is designed to optimize ion transport efficiency while maintaining structural integrity under the high thermal and electrical stresses associated with rapid charging.
Our product designed to maximize battery energy density and reduce overall weight without compromising safety. We possesses the capability to produce base films as thin as 4μm which is “super-thin” singlesided coatings. This allows battery manufacturers to fit more active material into a cell, directly increasing the efficiency of a battery.
Our mission to advancing environmental stewardship through focus on low-carbon manufacturing and sustainable product lifecycles. As a cornerstone of INV’s ESG strategy, our separator is produced in a high intelligence facility powered by extensive rooftop photovoltaic systems. By integrating recovery systems that capture and process waste gas, liquid, and sewage, INV ensures that this product line contributes to achieving the lowest global emission levels in the industry.
Our product specifically engineered for maximum thermal and chemical stability to prevent battery failure
or thermal runaway. INV utilizes advanced Ceramic Coating technology, which prov ides low moisture
content and exceptional stability at high temperatures. It also incorporates low shutdown temperature and
prevent overheating during a shor t circuit.
