2025 Patent Trends: Li-ion Batteries 2025 Li-ion patent landscape combines rising interest in advanced materials with clear country-specific technology choices.
In 2025, patent applications increased for advanced materials including NMC, LFP, LMFP, lithium-metal, silicon anodes and solid-state batteries, while other materials remain stable.
Material focus differs by country, especially for lithium metal oxides vs. lithium metal phosphates. China and India show a balanced 50:50 ratio, whereas most other countries exceed 75% oxide-based filings. 2024-2025 PATENT APPLICATIONS BY MAIN Li-ION BATTERY TECHNOLOGIES
2025 PATENT APPLICATIONS RELATED TO Li-ION BATTERIES BY COUNTRY
