TYFAST

TYFAST builds lithium-ion cells around a lithium vanadium oxide anode discovered by its founders at UC San Diego, aimed squarely at the vehicles a passenger-car battery can't serve. An excavator, a mine hauler, or a long-haul truck draws power in spikes, cycles several times a day, works through temperature extremes, and must last years longer than a sedan's pack. Graphite cells put in that duty either get oversized, get babied by thermal management, or wear out.

So diesel keeps the job. Heavy duty vehicles trail passenger cars in electrification by more than a decade while accounting for a disproportionate share of transport emissions and the worst of the air where people work. A chemistry built for that duty cycle, rather than adapted to it, is what turns those fleets electric. The anode is where that argument is won or lost.
