This Swagelok removable mold, model SM1-12-20 from Zhongke Wanyuan, is designed for battery performance testing and experimental setups. It is constructed from conventional stainless steel, making it suitable for organic electrolyte systems such as lithium-ion, sodium-ion, and zinc-ion batteries. For specialized applications like magnesium or aluminum ion battery testing, a custom-machined molybdenum electrode version is available. The mold offers good sealing performance and supports batch testing, with electrode dimensions customizable to specific requirements—available in size ranges of 12–15 mm or 16–20 mm for molybdenum electrodes. Optional material variants include titanium and molybdenum, with pricing reflecting the material and size. A minimum order of three molds of the same specification is required (rack not included). This tool is well-suited for researchers needing reliable, adaptable test fixtures for advanced battery material evaluation.
