From little hand-held physics to medium sized buses and trucks, electrical vehicles, to marine vessels and good grid storage systems, coat weight measurement of lithium battery technology is making our lives different.
To advance the battery system, the emergence of upper quality extractor film, new coatings of extractor film for higher potency, and also the uniform coating of the anode and cathode materials. however, the coating thickness and weight should be optimum to make sure a longer-lasting and safer battery.
Separator film is one amongst the key parts of a lithium battery
it’s a skinny however pervious layer of film accustomed separate the anode from the cathode and forestall short circuiting whereas facilitating the flow of charged ions. extractor films are sometimes created either by a dry or wet method to make the specified small porous structure. Consistent thickness of the film and solid distribution of the pores are so necessary to optimize performance and lifetime of the battery. conjointly extractor films act as a security web against thermal runaway. because the temperature of the cell will increase, the extractor film melts, closing the pores and stopping particle transfer and current flow at intervals the cell. to boot, extractor film may also be coated with ceramic or another material to boost potency.
Uneven coat weight measurement can ultimately lead to poor construction of the battery
This may be worse, making a hotspot that may lower the potency of the battery, shorten its life, increase charge time and/or increase the chance of thermal runaway. to boot, coated merchandise isn’t recoverable. Therefore, a few correct measuring of the coat weight on each side of the substrate is overriding to dominant and perfecting the method and rising yield and quality.
A digital basis device is one amongst the foremost ideal technologies for measure the coatings on the cathode and anode parts as a result of it options exceptionally high signal with extraordinarily low noise and a singular atom slot pure mathematics that ends up in the foremost correct coating weight measuring potential and highest edge resolution.
Infrared Thickness Device
For measuring of coat weight measurement, the newest on-line net measuring technology uses a few infrared thickness devices, that uses the total spectral response of the close to infrared vary to research materials on the road, providing precise, multi-component thickness information that improves production quality and reduces waste. as a result of the device analyzes the total spectral response of the extractor film to IR energy, it provides the foremost correct thickness measuring potential. Combined with the integrated mass balance formula, and also the ability to figure on each wet and dry processes, this net gauging technology is especially helpful for the measuring and management of all sorts of extractor film.
