Sand. It’s coarse, it’s rough, and it can make for a great battery. And as weird as that might sound, it’s just one example of the many earthy materials currently used for thermal energy storage (or TES). A while back, we covered the debut of the world’
It might surprise you to learn that the basic chemistry of the lithium ion battery at the heart of a brand new Tesla or iPhone hasn’t changed all that much in the last 30 years.1 So, when several of you left comments pointing me in the direction of
There is no perfect battery. Every one of them has pros and cons. One might be perfect for electric vehicles, but horrible for another use case because of cost, longevity, or power output. But what if you combined two separate technologies into one package? Better yet, what if you could
Imagine getting the energy needed to power our phones, light up our homes, or drive our cars, from thin air. And no, we’re not talking about Nikola Tesla’s dream of wireless power a century ago, but a new and accidentally electrifying discovery along those lines from the University
The saying goes that “one man’s trash is another man’s treasure,” and as we speak, researchers around the globe are experimenting with taking this phrase literally. Right now, it’s possible to turn leftovers from brewing beer into batteries and to generate electricity from wastewater. There’s a
What do you do if a satellite runs out of batteries? It’s prohibitively expensive to send a team into orbit and pop in some new AAs, and as a result many satellites use very efficient, reliable and long-lived nickel-hydrogen batteries. We’re talking about batteries that may last decades.
It’s been nice to see the growing popularity of electric vehicles these last few years, but EVs need batteries and batteries don’t last forever. In fact, the first generation of EV batteries are already dying, and there’s an absolute dead battery typhoon coming. Lithium battery recycling is
For years, special kinds of semiconductors called perovskites have promised revolutionary improvements compared to traditional silicon solar cells. Perovskites could hold the key to higher efficiency at lower costs. In some cases perovskites have been shown to offer a 250% performance boost. But scientists have been working on this tech
There’s no shortage of potential solutions to the world’s critical need for renewable energy storage. But there is a shortage of accessible and cheap resources to use for those solutions. With the limitations of materials like lithium and vanadium in mind, it’s logical to look for alternatives
Adding solar panels to your home is a bright idea, but according to one report from 2020 only about 6% of installed residential solar systems included battery storage.1 2 That’s a bit of a power outage in the world of renewable energy. But with a home battery, you’
Who doesn’t want a smartphone, laptop, or EV that can charge in minutes? Or a device that holds its charge just as well when it’s 5 years old as the day you plugged it in for the first time? Faster-charging, longer-lasting, and cheaper energy storage options are something
Grid-scale lithium-ion batteries are our current go-to chemical energy storage solution, but they present their own challenges in safety, sustainability, cost, and longevity. However, the competition is … heating up. New forms of thermal energy storage systems built using abundant, cheap materials are on the rise. One company is aiming to
