FAQ
It is professionally customized for lithium-ion batteries and Ni-MH batteries, and also widely compatible with new energy vehicle power batteries, industrial & household energy storage batteries, consumer electronic batteries, medical device batteries, wearable device miniature batteries and engineering vehicle starting batteries. It can be used as current collector and electrode substrate for all mainstream new energy batteries.
Different from woven mesh with easy loose wires and uneven conductivity, our expanded mesh adopts one-piece integral stretching forming with no welding joints and broken wires. It features more uniform conductivity, higher structural stability, better ductility, and is not easy to deform during battery winding and lamination. Meanwhile, the three-dimensional mesh structure provides larger coating adhesion area, which effectively prevents electrode active materials from falling off, greatly improving battery cycle life.
Pure copper mesh: Ultra-low resistance, best conductivity, ideal for lithium battery negative electrode current collectors;
Pure nickel mesh: Excellent corrosion resistance and weldability, suitable for Ni-MH batteries and high-stability battery electrodes;
Titanium mesh: High temperature and oxidation resistance, applied for high-end medical and aerospace backup batteries;
304/316L stainless steel mesh: Cost-effective, strong structural strength, suitable for general energy storage battery support and conductive parts.
We provide full-range customized services. We can customize product thickness, width, length, aperture, expansion ratio, surface treatment and cutting size according to customer drawings, samples and actual battery application scenarios, to provide one-stop exclusive conductive mesh solutions.
We have sufficient conventional specifications in stock for fast delivery. For customized products, we arrange production according to order quantity with stable batch supply capacity. Our annual output is sufficient to support large-scale procurement of global new energy battery manufacturers, with reliable after-sales service and long-term stable supply guarantee.
