Electrification is all the rage these days. From cars and motorcycles, to scooters and even lawnmowers, the push for a greener, more sustainable future is pretty much everywhere you look. But as exciting as all this progress may seem, the road ahead is still riddled with challenges, and at the center of it all lies one big hurdle: battery technology.

Thankfully, we’ve seen quite a lot of innovations in recent years, from increasing battery capacity and efficiency to enhancing safety measures to keep things from catching fire. But one of the latest breakthroughs has the chance to pretty much change the game for the entire EV industry.

It comes from a collaboration between Japan’s Doshisha University and TDK Corporation. Their development? A quasi-solid-state lithium-ion battery (LIB) that might just tick all the right boxes.

Before we dive into this new tech, let’s first take a look at the stuff powering most modern-day EVs. Traditional lithium-ion batteries, while efficient for the most part, come with some drawbacks, including fire risks and performance trade-offs when pushing for higher energy densities. This new quasi-solid-state battery combines liquid and solid electrolytes, offering a middle ground (between traditional and solid-state LIBs) that supposedly enhances both safety and durability.

What’s more, it retains high energy density, a critical feature as we look toward more demanding applications in EVs.

According to the research team, their design offers a more accessible alternative compared to full solid-state batteries, which can face issues with lithium-ion transfer and solid-to-solid interface stability during charge and discharge cycles. By introducing “joints” that are elastic, non-flammable, and highly conductive, the battery overcomes many of these limitations.

The result? A supposedly highly stable battery that can endure high temperatures (up to a claimed 150 °C) with minimal heat generation.

But let’s veer away from all the nerdy jargon for a bit, and get into why this matters for folks like you and me.

For electric motorcycles and powersports vehicles, weight, energy density, and safety are critical considerations. A battery like this could unlock the potential for lighter, more compact designs while also boosting performance and durability. Imagine an electric dirt bike like the Stark Varg, but turn its range and efficiency up to eleven. Or an electric superbike that offers extended range without sacrificing performance and safety. I mean, these are things that already exist, but this development stands to drive them even further into the future.

So, is this the game-changer we’ve been waiting for? Only time will tell, but it certainly feels like a step in the right direction. Fingers crossed that this quasi-solid-state technology finds its way into mainstream applications sooner than later.
