A breakthrough in solid-state lithium-sulfur batteries has quietly achieved double the energy density of standard EV batteries — a quiet laboratory victory that... (opens in new tab)

The single greatest constraint on electric vehicles, more than anything else, is the battery. Not the motor. Not the software. Not the charging network. The battery — its weight, its cost, the distance you can travel on a single charge — is what shapes almost every other compromise an EV makes. A heavier battery means […]
