Ever wondered why your battery doesn't last as long as you'd like? One big reason is the way lithium metal anodes behave during operation. These anodes can change a lot in size and shape, which can cause big problems like dendrites. Imagine dendrite formation like the growth of tiny lithium branches. These branches can cause short circuits in batteries, maki...
Zinc might be the star of the future in energy storage, but it's been held back by some serious issues. Think dendrites, corrosion, and hydrogen bubbles – all messing up the party at the electrode/electrolyte interface. Scientists have found a clever way to turn the tables. They've figured out how to use the byproducts of zinc's corrosion and passivation, called zinc...

Electric vehicles (EVs) are taking the world by storm. But before EVs can truly replace traditional cars, their batteries need a major upgrade. Scientists use a method called DEMATEL to figure out how factors in battery tech affect each other. This method is great for complex systems, but real-world decisions aren't always clear-cut. So, researchers added a new twist...
Imagine a tiny molecular boat and paddle system designed to fix itself in just two minutes. This is the story of a unique glue, or binder, created to help silicon batteries last longer. Silicon batteries have a big problem: they can swell up and break during use. Scientists are working on self-healing binders to solve this issue. However, making a binder that's both ...
The world's top EV battery maker, CATL's Robin Zeng, has some doubts about Tesla's 4680 battery project. He thinks it might not live up to expectations. These special batteries, named after their size (46mm by 80mm), were supposed to be a game-changer. Tesla said they'd have five times the energy and cost less. They're already in some Tesla cars, like the Cybertruck....
Did you know that Apple wasn’t just creating phones and computers? They were also dabbling in the world of electric vehicles (EVs). For years, rumors swirled about Apple’s secret car project. But instead of teaming up with big names like Volkswagen or McLaren, Apple worked with a surprising partner: Chinese EV maker BYD. This collaboration started back in 2017. Toge...
