Toyota claims it has made a breakthrough in solid-state battery tech that could impact electric cars in a huge way. Here’s how.
The biggest question first-time buyers have when buying an EV relates to range. “How far can I go in this thing?”
It makes sense. While making it 300 miles or so isn’t bad for a modern EV, it does mean that you have to stop at a charging station more regularly than you have to fill a tank on a gas-powered car, and charging can be a little time-consuming. So what’s the fix? Either better range or faster charging — and Toyota says that it has cracked the code for the former.
At a technical briefing in early July, Toyota announced that it has made a breakthrough in battery technology that will allow it to eventually create batteries that offer a whopping 745 miles of range on a single charge — and that it’s aiming to create a battery that would give an electric car 900 miles of range.
But don’t put off that Prius Prime purchase just yet. As with all new technologies, there are still hurdles to clear and a long road ahead. Here’s everything you need to know about Toyota’s solid-state battery tech, and what it means for EVs going forward.What is a solid-state battery?
The way a conventional battery works is quite simple. It has a cathode on one side and an anode on the other. Generally, batteries create a reaction by causing electrons to flow from one side to the other, which in turn creates a circuit and powers your device.
To date, EVs have used essentially the same kinds of batteries as those used in our phones, smartwatches, and so on. In these batteries, the cathode and anode live right next to each other, separated by a porous plastic membrane that allows the liquid electrolyte solution to flow from one side to another, generating current.
