running out, look away now. Envia has unveiled a new cell that boasts a record-breaking energy density of 400Wh/kg (most currently offer between 100 and 150). It's estimated that when commercialized, this could bring the cost of a 300-mile range EV down to as little as $20,000. The performance gains come from a special manganese-rich cathode and silicon-carbon nano-composite anode combination. The battery maker is also partly owned by GM, which unsurprisingly means we're likely to see these very cells in its EVs in the future. Perhaps with the right choice of upholstery, we might see even better savings? Want to know more? Tap the fully charged press release parked just after the break.
