New “Quasi-Solid-State” Battery Tech Just Might Be An EV Game Changer
It promises improved safety and thermal stability compared to conventional lithium-ion batteries.

Fair dinkum, we've seen some ripper innovations in recent times, from batteries getting a whole lot bigger and more efficient to improving safety features so they don't catch on fire. But one of the latest breakthroughs has got the potential to pretty much shake things up for the entire EV industry.
Their development? A battery that's a bit like a lithium-ion battery, but in a different form – one that could be a real game-changer.
Before we move on to this new technology, let's have a look at what's driving most modern electric vehicles. The standard lithium-ion batteries, which are generally quite efficient, do have some downsides, including the risk of fires and compromises on performance when trying to increase energy density. This new quasi-solid-state battery uses a mix of liquid and solid electrolytes, offering a compromise between traditional and solid-state lithium-ion batteries, which is said to improve both safety and lifespan.
What's more, it retains a high level of energy storage, a crucial characteristic as we look towards more demanding uses in electric vehicles.
According to the research team, their design provides a more accessible option compared to full solid-state batteries, which can experience problems with lithium-ion transfer and solid-to-solid interface stability during charging and discharging cycles. By introducing "joints" that are elastic, non-flammable and highly conductive, the battery overcomes many of these limitations.
The outcome? A supposedly highly stable battery that can withstand extreme heat (up to 150 °C) with minimal heat emission.
Let's have a break from all the technical talk for a bit, and get to the point of how this affects people like you and me.
And powersports vehicles, weight, energy density, and safety are critical factors to consider. A battery like this could unlock the potential for lighter, more compact designs, and also boost performance and durability. Just imagine an electric dirt bike like the Stark Varg, but crank up its range and efficiency to the max. Or an electric superbike that's got extended range without sacrificing performance or safety. I mean, these are things that already exist, but this development will take them to the next level.
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 new solid-state technology makes it into everyday use sooner rather than later.
