- Expiry of LFP battery patents in 2022 made the technology freely accessible, transforming the EV industry.
- LFP batteries use lithium iron phosphate, offering lower cost, low toxicity, and superior thermal safety.
- Tesla's adoption of LFP batteries marked a trend accelerating in Western markets and renewable energy storage.
- Companies now focus on secondary innovations like energy density, safety, fast-charging, and cost reduction.
- Freedom-to-operate (FTO) analysis is crucial due to remaining secondary patents on additives, coatings, and production methods.
- Challenges include recycling economics, supply chain dependencies on China, and infrastructure misalignment in regions like the UK.
- Competitive advantage in LFP technology will come from further innovations, trade secrets, and strategic partnerships.
