Latest Patents

Gocheva's latest patents include a method for producing iron oxyfluoride positive electrode active substances and a cathode active material for non-aqueous electrolyte secondary batteries. The first patent outlines a technology for producing a positive electrode active substance primarily composed of FeOF, which boasts a sufficient charge-discharge capacity. This method involves admixing iron oxide (FeO) and iron fluoride (FeF) in solid states, followed by melt-quenching the mixture in an inert gas atmosphere. The resulting positive electrode active substance contains at least 50% by weight of FeOF, with the remainder being iron fluoride and/or iron oxide.

The second patent focuses on adjusting a cathode active material that includes guest cations such as sodium and lithium. This involves subjecting alkaline metal fluoride and transition metal fluoride to a mechanical milling process to produce a metal fluoride compound. The process is ideally conducted using a planetary ball mill, enhancing the efficiency of the material's production.
