Sodium metal batteries are a big deal because they can store a lot of energy. But there's a problem: tiny branches called dendrites can grow inside them, which messes things up. These dendrites cause the battery to lose power and even short circuit. Scientists have found a clever way to deal with this issue. They made a special surface for the battery's current coll...
Tesla's electric vehicles (EVs) rely on lithium-ion batteries, which are common in most EVs today. These batteries are powerful and efficient, but they aren't perfect. They can lose charge even when the car isn't being used. This is called discharge. There are two main types of lithium-ion batteries. One type is used mostly in the U. S. and contains aluminum, cobalt...
The stock market is taking a breather on Wednesday, staying close to its peak levels. After a couple of days of big gains, investors are now wondering if the recent surge will continue. The S&P 500 is just a hair away from its all-time high, while the Dow Jones is down a bit, and the Nasdaq is up slightly. Oil prices have been all over the place this week. They drop...
Samsung is making strides in the battery technology field, but it's not rushing. This company is known for its innovative gadgets, but battery tech hasn't seen much change lately. However, behind the scenes, things are different. Samsung is quietly exploring new battery technologies. The focus is on creating a battery that lasts longer and is safe to use. This is a ...
The electric vehicle (EV) revolution is in full swing, and China is at the heart of it. Two giants, CATL and BYD, are leading the charge in battery technology. CATL, the world's top battery maker, recently announced a new battery that can power an EV for about 320 miles on a single charge. This is a significant leap from BYD's latest offering, which promises around 2...
Zinc-based batteries are gaining attention as a safe and reliable way to store energy. These batteries, known as zinc aqueous batteries (ZABs), have a lot of potential, but they have some big problems. Specifically, they struggle with side reactions and dendrite growth, which make it hard to use them on a large scale. To tackle these issues, researchers have come up...
A new player in the battery game is here to shake things up. Daqus Energy has been quietly working on a new material called TAQ. It's cheaper and lighter than what's out there now. This could be a game-changer for electric sports cars. But there's a catch: it's not perfect yet. The big deal with TAQ is that it doesn't rely on expensive metals like nickel or cobalt. ...
TECNO is set to unveil the Spark Slim at MWC 2025. This phone is incredibly thin, measuring just 5. 75mm. It's not just about being slim; TECNO claims it has the largest battery in a phone this thin, with a 5, 200mAh capacity. This is a big deal because most super-thin phones have much smaller batteries. The Spark Slim is designed to compete with high-end phones lik...
Lithium ions are tiny particles that could change how we store and use energy. Scientists have created a special gel to make these particles move faster and more freely. This gel is made from polymers, ionic liquids, and lithium salts. It acts like a superhighway for lithium ions, allowing them to travel more efficiently. Lithium ions often slow down when there are ...
Imagine a world where batteries are cheap, safe, and powerful. Sounds like a dream, right? Well, zinc-ion batteries are stepping up to make this dream a reality. But hold on, there's a twist. When zinc is used as the anode, things can get a bit chaotic. Tiny, unwanted branches called dendrites can grow, causing poor performance and instability. Plus, zinc doesn't alw...
