<h1>Pharmaceutical company develops breakthrough sodium-ion battery technology using Prussian White cathode material, files provisional patent</h1> A pharmaceutical company has achieved a breakthrough in sodium-ion battery technology by successfully synthesizing Prussian White, a high-performance cathode material. The company filed a provisional patent for its proprietary synthesis process and is advancing toward pilot-scale manufacturing. The breakthrough occurred when researchers working on a radioactive poisoning drug discovered the battery potential of Prussian White. Starting with basic laboratory equipment, the team developed a full electrochemistry facility and now produces the material at kilogram scale. The technology achieves energy density exceeding 150 mAh/g, comparable to lithium iron phosphate, using abundant materials like sodium and iron. The company is establishing a dedicated energy division and plans to have pilot-scale production operational by early 2026, targeting applications in grid storage, backup systems, and electric vehicles.
