Guilv achieves breakthrough with 8-micron ultra-thin battery foil

State-owned Guizhou Guilv New Materials Co has achieved a major technological milestone by announcing its 8-micron (0.008 millimeters) ultra-thin battery foil, a breakthrough in micron-level manufacturing that opens new opportunities in the market for key materials used in new energy batteries.

Battery-grade aluminum foil is critical in power and energy storage. Its thickness, tensile strength, and elongation rate directly impact the overall performance and lifespan of batteries. As the industry moves into a new era of ultra-fine competition, micron-level precision has become a decisive factor in market differentiation.

In response to market demands, Guilv New Materials has taken the lead in advancing the development of ultra-thin battery foils. The company assembled a core team spanning process engineering, quality control, and equipment optimization. Through hundreds of parameter adjustments and dozens of formulation tests, the team overcame major technical challenges, including stress control and surface quality.

The production of 8-micron foil marks a significant step, with key performance indicators such as tensile strength and elongation exceeding expectations, setting a new benchmark for the company's capabilities in the ultra-thin battery materials sector.
