Engineered for the demanding requirements of the global energy storage industry.
The global energy transition has placed Lithium-Ion Battery (Li-ion) technology at the forefront of the industrial revolution. As a critical component in the manufacturing process, Li-Ion Battery Knives have evolved from simple cutting tools into high-precision engineering masterpieces. With the exponential growth of Electric Vehicles (EVs) and large-scale Energy Storage Systems (ESS), the demand for high-performance tungsten carbide slitting knives has reached unprecedented levels.
The "Giga-factory" era requires slitting tools that can operate at higher speeds with minimal downtime. Manufacturers are now looking for knives that offer 200% more longevity compared to standard steel blades.
The industry is moving towards ultra-thin separators and solid-state battery research. This requires knives with edge roughness (Ra) levels below 0.05μm to prevent micro-cracks during the slitting process.
Advanced manufacturers like Shen Gong are introducing "Circular Economy" models, providing resharpening and recycling services for used carbide knives to reduce the carbon footprint of battery production.
Established in 1998 in Chengdu, China, Shen Gong has grown into a national high-tech enterprise. We specialize in the entire lifecycle of cemented carbide industrial knives—from RTP powder manufacturing to finished, high-precision products.
Our vision is simple yet profound: "Make Sharp Edge Always in Reach." We focus on WC-based cemented carbide and TiCN-based cermet, ensuring our tools meet the rigorous standards of the lithium-ion battery sector, where even a microscopic burr can lead to battery failure or safety hazards.

Procurement teams in Europe, North America, and Southeast Asia face the challenge of balancing tool life with cost-per-cut. As the global supply chain shifts, the demand for localized application support coupled with high-volume manufacturing capabilities is paramount. Shen Gong serves this need by offering:
As a leading China-based factory, Shen Gong leverages the world's most robust tungsten supply chain and a massive pool of engineering talent. This allows us to offer premium carbide grades like our proprietary ETaC-3 coating, which provides a mirror-finish edge with zero notches—preventing material sticking during the slitting of cathode and anode electrodes.
Beyond Battery: Precision Cutting Solutions for Every Major Industry.
In the lithium-ion battery industry, the slitting of electrode foils (Copper for anode, Aluminum for cathode) is a make-or-break step. Our engineering team, with over two decades of expertise, focuses on three critical factors:
As the market shifts towards Solid-State Batteries and Silicon Anodes, the mechanical properties of the foils change. Shen Gong is already partnering with leading R&D centers to develop the next generation of Cermet-coated knives that provide even lower friction coefficients, further extending tool life and improving battery safety.
