Slate Auto switches battery chemistry for its affordable EV truck
Tags Infrastructure · Consumer
Slate Auto, the EV startup building a sub-$30,000 pickup truck, changed its battery type from the original chemistry — a decision years in the making according to company leadership. The switch reflects the evolving battery supply chain and cost optimization required to hit the company's aggressive price target. The move highlights the battery chemistry tradeoffs (energy density vs. cost vs. supply chain security) that define EV startup survival.
Technical significance
Battery chemistry selection is the single most consequential engineering decision for an EV startup — it determines cost floor, range, charging speed, and supply chain resilience. Slate's willingness to switch chemistries late in development suggests either the original choice couldn't hit cost targets or a new chemistry (likely LFP or sodium-ion) became economically superior. This mirrors broader industry trends toward LFP for affordable EVs despite its lower energy density.
