Lithium-iron phosphate (LFP) batteries are the single most dominant product in the world of renewable energy right now, across EVs and energy storage and devices, posting far more dynamic growth figures than any other major segment. They’re a cheap, reliable and mature product type – but all of this is not enough to completely secure their position. The next big innovation in batteries is solid-state, first semi-solid-state and then all-solid-state, and this could entail a change in anode materials from the existing LFP and ternary high-nickel mainstream. Silicon-based cathodes may also supplant lithium-based solutions on that end as well. Given that LFP products are in such a strong position across availability, cost and reliability, it’s hard to see solid-state as…
