The Battery Patent Race
Battery technology is one of the most active areas of patent filing worldwide, driven by the electric vehicle transition and energy storage demand.
Key Technology Segments
1. Cell Chemistry Patents covering cathode materials (NMC, LFP, NCA), anode materials (silicon, lithium metal), and electrolyte formulations represent the largest segment.
2. Solid-State Batteries Solid-state battery patents are growing fastest, with major automotive and battery companies racing to patent oxide, sulfide, and polymer electrolyte approaches.
3. Manufacturing Process Cell manufacturing innovations—dry electrode coating, laser processing, and formation protocols—are increasingly patented as companies seek production advantages.
4. Battery Management BMS (battery management system) patents covering cell balancing, state estimation, and thermal management continue to grow with vehicle electrification.
Geographic Analysis
Japan leads in total battery patent filings, followed by China, South Korea, the US, and Germany. Chinese filings are growing fastest, while Japanese and Korean companies hold the most mature portfolios.
