Application: Novel organic electrodes and their use in electrochemical systems (Patent ID: US20240105945A1)
The patent filed by Electricite de France SA pertains to positive electrodes for batteries based on organic active materials, specifically molecules of thianthrene substituted at specific positions. These electrodes are designed to have electrochemical properties suitable for use in recyclable batteries, replacing conventional electrodes based on mineral salts. The positive electrodes consist of the organic active material, an electronically conductive material, and a current collector. The active material is present in a specific content range, and the conductive material can be selected from various options like carbon black, graphite, or conductive organic polymers. Additionally, the electrodes may include a binder in a specific content range to enhance their performance.
Furthermore, the patent also covers a method for preparing these positive electrodes, involving the creation of an electrode ink, casting it onto a current collector, and drying it. The patent extends to batteries incorporating these positive electrodes, along with a negative electrode and a non-aqueous electrolyte solution containing specific salts in organic solvents. The electrolyte can be a solution of LiPF6 in a carbonate-based solvent, and the binder for the electrodes can be selected from a variety of options like polyvinylidenes or polytetrafluoroethylene. The batteries described in the patent are rechargeable and utilize specific organic solvents like diethyl carbonate or propylene carbonate in combination with LiPF6 salt.
