iPod inventor and Nest founder Tony Fadell invests $18.5 million in battery startup
iPod co-inventor Tony Fadell is backing a battery company that says it’s found a way to store more energy using silicon scrap waste. Fadell’s investment firm, Future Shape, is among the contributors to Advano’s $18.5 million Series A funding round. It’s Fadell’s first battery investment. Silicon could be key to building more powerful batteries. The anodes of most existing systems are made with graphite.
