Sila Nanotechnologies next-generation battery technology made its commercial product debut Wednesday in the new Whoop fitness tracker, a milestone that caps a decade of research and development by the Silicon Valley startup all aimed at cracking the code to packing more energy into a cell at a lower cost. Billions have been spent over the past few years on improving battery chemistry, with different startups aiming to either replace the anode or the cathode with a conversion material, like silicon or even lithium in the case of solid state companies. Sila Nano’s battery chemistry recipe replaces graphite in a battery cell’s anode with silicon to create a more energy-dense and cheaper battery pack. Other companies, like BASF are focusing on creating a high energy dense cathode.  While numerous companies are working on a variety of different battery chemistries, they have yet to take over the traditional cell technology found in today’s lithium-ion cells.  The Sila battery used in the upcoming Whoop 4.0, the company’s latest health and performance tracker, could be the first time in the last few decades the world has seen a next-generation battery chemistry ship to market.  “Launching a small fitness tracker doesn’t seem like a big thing, but this is really the first device in the market that proves our breakthrough, and over time, this will scale and lead to the electrification of everything,” Gene Berdichevsky, founder and CEO of Sila Nano, told TechCrunch. Electric vehicles, and Sila Nano’s role in powering them, is at the top of Berdichevsky’s “electrification of everything” list. And the company has already made headway. Sila Nano has joint battery ventures with BMW and Daimler to produce batteries containing the company’s silicon-anode technology, with the goal of going to market in the automotive industry by 2025.  “You can translate this success with Whoop to cars in many ways,” said Berdichevksy
