FDK CORPORATION

Slurry compositions and coating processes for battery electrodes, including binder/active-material slurries, surface coating layers, and electrode-to-foil adhesion for cathode and anode.

Software, algorithms, and associated hardware for monitoring, controlling, and optimizing battery performance, safety, and lifespan, including charge/discharge cycles, thermal regulation, and system integration.

Process and equipment for producing solid-state battery cells, including solid electrolyte synthesis (sulfide/oxide/polymer), thin-film deposition, lamination, sintering, dry-electrode fabrication, and stacking under controlled atmosphere.

Focuses on the structural integrity, housing, mounting, and physical integration of battery cells into robust and protected packs within electric vehicles, including manufacturing considerations.

Design and control of power supply architectures that combine multiple power sources (e.g., AC grid, DC battery, generators) or modular battery units, often featuring switching, conversion, and redundancy for enhanced reliability and flexibility.

Processes and apparatus for disassembling spent batteries and recovering valuable materials (e.g., metals, electrolytes, plastics) through mechanical, chemical, or electrochemical methods for reuse or sustainable disposal.

Integration of power converters with energy storage devices (batteries, supercapacitors) or grid interfaces, often involving AC/DC conversion, power flow management, and fault handling for hybrid power systems or specific applications like EVs or PV.

Technologies for efficiently delivering power to electric vehicles, encompassing fast charging, wireless charging, and smart grid integration, alongside vehicle-side control and management of the charging process.
