Slate’s decision to ditch nickel and cobalt for cheaper lithium-iron-phosphate (LFP) cells highlights the evolving landscape of electric vehicle batteries. The startup’s move to a simpler, more affordable pack underscores the changing economics of EV technology.
Initially, NMC cells were favored for their energy density, but as the LFP supply chain has shifted to China and concerns over domestic sourcing have waned, automakers like Slate are opting for cheaper alternatives. This shift means longer charging times but a more competitive price point for consumers who prioritize range over absolute mileage.
Modern variations of LFP cells are closing the gap in range, and their lower cost makes them an attractive option for affordable EVs like Slate’s truck. The industry is also moving towards cell-to-pack construction, which simplifies manufacturing processes and boosts energy density—a perfect fit for small electric vehicles where space is at a premium.
The transition to LFP cells represents a significant shift in battery chemistry, driven by economic factors rather than technological limitations. As charging networks expand, range anxiety becomes less of an issue, making cost-effective solutions like Slate’s EV more appealing to a broader audience.
