Titanium Foil For Battery

Shaanxi Chenxin Titanium Industry specializes in mass-producing foreign trade-grade Titanium Foil for Battery. Our products strictly adhere to the ASTM B265 American standard and are specifically developed and produced for electrochemical scenarios such as energy storage batteries, lithium batteries, solid-state batteries, and flow batteries. Distinct from medical and general electronic titanium foils, battery-grade titanium foil emphasizes superior electrolyte corrosion resistance, stable electrochemical performance, and low interfacial impedance characteristics. It effectively addresses industry pain points such as the corrosion and oxidation susceptibility of traditional copper and aluminum foils, as well as rapid battery cycle degradation. Our factory can stably produce ultra-thin specifications ranging from 0.02 to 0.2mm exclusively for batteries, supporting full-size and surface performance customization. It serves as the core current collector and electrode substrate for high-end energy storage, new power batteries, and electrochemical energy storage devices, widely supplying the European and American new energy foreign trade markets.

The core benefit of battery-three titanium foil is that it is highly electrochemically stable and resists electrolyte corrosion, which allows it to be a high value-added new energy battery packaging material. Conventional copper foil and aluminum foil will be dissolved, oxidized and side reactions under high voltage and strong acid-base electrolyte environment, result in battery capacity decay, battery swelling, battery life shortens. But the surface of AS battery-grade titanium foil forms a dense self-passivating oxide film that in lithium batteries, flow batteries and sodium salt battery electrolytes over long periods of cycling is neither corrosive nor soluble.This stable interface impedance significantly enhances the battery's cycle life and safety factor. Additionally, titanium foil is lightweight, thermally uniform, and non-magnetic, making it suitable for high-density battery integration designs, effectively increasing the energy density of the cells.

In the segmented scenarios of new energy batteries, titanium foil for batteries possesses irreplaceable application advantages. In the field of power batteries, ultra-thin titanium foil, serving as a positive electrode current collector, can withstand corrosion from high-voltage charging and discharging, adapting to high-frequency cycling conditions. In the field of solid-state batteries, flat and stress-free titanium foil substrates enable uniform coating of active materials, enhancing the stability of the battery cell. In the field of flow energy storage batteries, titanium foil electrodes are resistant to strong corrosion, adapting to long-term energy storage conditions. In the field of micro-energy storage batteries, ultra-thin and lightweight specifications can compress the internal space of the battery, adapting to miniaturized energy storage devices. Compared to other metal foils, titanium foil for batteries is resistant to high temperatures, does not release hydrogen, and has no metal impurity precipitation, greatly reducing the risk of battery thermal runaway and adapting to high-end safe energy storage demands.

Our factory's battery-specific titanium foil adopts ASTM B265 American standard grades, matching corresponding materials for different battery operating conditions, covering conventional energy storage, power batteries, and high-end solid-state battery scenarios. The dimensional parameters are precisely adapted to battery coating, lamination, and packaging processes.
The product supports precise customization of thickness, width, and length. It can be customized with a matte surface, flat mirror surface, or roughened adhesive surface specifically for batteries, adapting to different coating requirements of electrode materials. It eliminates issues such as delamination and powder falling off, perfectly fitting the mass production process of new energy batteries.
