William Fitzhugh

William Fitzhugh is the co-founder and CEO of Adden Energy, a Harvard spin-out scaling a self-healing, solid-state lithium-metal battery that has charged in as little as three minutes and survived more than 10,000 cycles in lab cells. A Harvard PhD in applied physics, he is trying to turn a coin-cell breakthrough into a roll-to-roll pilot line and, eventually, batteries that let an EV recharge in the time it takes to fill a gas tank.
