Tesla (NASDAQ:TSLA) has a market cap near 900 billion and opened its Texas gigafactory in April. Lucid (NASDAQ:LCID) recently rolled out its first cars with 500-plus miles of driving range. In November 2021, Rivian (NASDAQ:RIVN) had the biggest initial public offering (IPO) since Meta (NASDAQ:FB). Every legacy automaker — from Ford (NYSE:F) to GM (NYSE:GM) to Volkswagen (OTCMKTS:VWAGY) — is investing tens of billions of dollars into electrifying their fleets.

The Electric Vehicle Revolution has unequivocally arrived.

But here’s the thing: It won’t go mainstream until we make better batteries.

The reality is that batteries make things work. But today’s versions are keeping electric vehicles from working as well as they could.

Sure, it seems counterintuitive, but it’s true. And to understand why, we need to take a quick trip back to chemistry class.

Electric Vehicle Battery Breakdown

Batteries comprise three things — a cathode, an anode and an electrolyte. Batteries work by promoting the flow of ions between the cathode and anode through the electrolyte.

Conventional lithium-ion batteries are currently the dominant status quo in smartphones, smartwatches, electric vehicles, so on and so forth. They are built on liquid battery chemistry.

That is, they comprise a solid cathode and anode with a liquid electrolyte solution connecting the two.

These batteries have worked wonders for years. But due to the constraints of liquid electrolytes, they are now reaching their limit in terms of energy cell density. That means if we want our devices to last longer and charge faster, we need a fundamentally different battery.

Insert the solid-state battery.

With solid-state batteries, the name pretty much says it all. Take the liquid electrolyte solution in conventional batteries. Compress it into a solid. Create a small, hyper-compact solid battery that — because it has zero wasted space — lasts far longer and charges far faster.

Of course, the implications of solid-state battery chemistry are huge.

Solid-state batteries could be the key to our phones sustaining power for days and smartwatches fully charging in seconds. And, yes, they could enable electric vehicles to drive for thousands of miles without needing to recharge.
