1. Composite Current Collectors | Ultra-Lightweight We specialize in vacuum coating processes for composite copper/aluminum foils. We precisely deposit high-adhesion base layers (e.g., Ti, NiCr) and highly uniform conductive seed layers (Cu, Al). This significantly reduces battery weight, increases energy density, and effectively prevents thermal runaway, comprehensively enhancing the battery’s inherent safety. 2. Solid-State Batteries | Performance Leap Developed specifically for semi-solid and all-solid-state batteries. We provide core target materials (e.g., Li₃PO₄, LiNbO₃) for the preparation of solid-state electrolytes and interface modification layers. This significantly improves cathode interface contact, substantially enhances ionic transport efficiency and gas tightness, and facilitates the mass production of high-safety, long-life battery systems.

3. Anode Protection and Pre-lithiation | Steady-State Gains Empowers the modification of silicon-based and metallic lithium anodes. Achieves efficient pre-lithiation of anode sheets through high-purity lithium vacuum evaporation, or deposits precision engineered SEI protective layers via sputtering. Effectively suppresses lithium dendrite growth, mitigates silicon-based volume expansion, and significantly improves initial capacity and long-term cycling stability. 4. Supercapacitors and Specialized Micro-Batteries | Precision Protection Supporting supercapacitors and thin-film micro-batteries. We provide high-performance metal electrode and insulating encapsulation coating solutions. These solutions effectively enhance device rate capability and resistance to environmental aging, perfectly meeting the power storage needs of IoT devices and applications in extreme operating conditions.
