Lithium Iron Phosphate Battery Current Collector Patent Landscape 2026
Lithium Iron Phosphate Battery Current Collector Patent Landscape
- 199 families, 130 filed in China alone. Filing activity has concentrated heavily in one jurisdiction, with the US a distant second at 36 and Europe, Japan, Korea and PCT filings trailing further behind.
- Filing peaked in 2025 at 23, after a flat mid-decade. 2022 sat at 17 — the field did not show sustained growth into the peak, and the 2026 count is still partial under the usual ~18-month publication lag.
- Recent-year momentum has gone quiet across the named assignees. Every assignee tracked for recent-year activity — including CATL, LG Chem and LG Energy Solution — shows zero filings in the latest year, LG Energy Solution down -100% YoY.
Filing trend and technology composition
A flat decade with a late peak
Filings ran at 6 in 2017, held near a midpoint of 17 by 2022, and reached a peak of 23 in 2025 before the partial 2026 count. That trajectory reads as flat-to-declining momentum rather than a growth curve — the peak is a late bump, not the top of a climb, and the 2026 figure will rise as later filings publish.
Concentrated in core battery classes
All 199 records touch H01M. The next-largest subclass, C01B (non-metallic elements and inorganic compounds), appears in only 9 records, with B82Y nanotechnology, C01G, C07C, C22C, H01L and B01J each contributing single digits. Claim activity outside the core battery-cell classification is marginal.
