Solid-state batteries could be the key to making our phones sustain power for days… enabling our smartwatches to fully charge in seconds… and, yes, allowing electric cars to drive for thousands of miles without needing to recharge. Of course, the implications of solid-state battery chemistry are huge. With solid-state batteries, the name pretty much says it all: Take the liquid electrolyte solution in conventional batteries, compress it into a solid, and create a small, hyper-compact solid battery that – because it has zero wasted space – lasts far longer and charges far faster. But, due to the physical constraints of dealing with a liquid electrolyte, they are now reaching their limit in terms of energy cell density – which basically means that if we want our phones, watches, and electric cars to last longer and charge faster, we need a fundamentally different battery. These batteries have worked wonders for years. That is, they’re made using a solid cathode and anode with a liquid electrolyte solution connecting the two. Batteries work by promoting the flow of ions between the cathode and anode through the electrolyte.Ĭonventional lithium-ion batteries – which are currently the dominant status quo in smartphones, smartwatches, electric cars, and so on – are built on liquid battery chemistry. How Solid-State Batteries Will Revolutionize EVsīatteries comprise three things. Sure, it seems counterintuitive, but it’s absolutely true and to understand why, we need to take a quick trip back to chemistry class. That harsh reality here is that while batteries make things work, today’s batteries are keeping EVs from working as well as they could. The EV Revolution has arrived.īut here’s the thing: The EV Revolution won’t go mainstream until we make better batteries. Every legacy automaker - from Ford to GM to Volkswagen - is investing tens of billions of dollars into electrifying their fleets.
