A significant challenge for undersea exploration is powering underwater cameras. Researchers can tether it to their vessel or send a ship and diver to recharge its batteries. MIT researchers are overcoming the challenge, developing a…

Let's face it; charging an EV takes more than a little time. Drivers want to charge and go quickly, but with current technology, speeding up the process can cause damage. Now, scientists have designed super-fast charging methods for…

Researchers at Boise State University developed a new approach to creating novel lithium-ion battery materials. Starting from an amorphous niobium oxide, they discovered that the act of cycling the material with lithium induces a…

Now there’s an easily fabricated, high-performance carbon microlattice electrode that may result in cheaper batteries powered by sodium ions. Tohoku University published the approach in the journal Small. Lithium-ion batteries are…

The design and optimization of the surface electrochemical active sites is hot research for catalysts and batteries. Lithium-sulfur batteries provide a high energy density while being low cost and environmentally friendly. Challenges still…

Battery recharging is problematic. With each subsequent charge, batteries decay. An international, multi-agency/university study published in Science looks at what drives a battery's lifespan and how those factors change over time in…

Globally, rare earth elements are highly hazardous to extract, causing significant environmental challenges. Researchers at the University of South Australia are finding ways to transform the recovery of rare earth elements and other vital…

Performance decline caused by repeated charge-discharge cycling in the cathodes is the bane of next-generation batteries. EVs need greater ranges, and the grid requires low-cost batteries to store intermittent clean energy. The…

Fitbit just recalled its Ionic smartwatch. It seems the lithium-ion battery can overheat and cause a burn. Take it off and contact Fitbit to receive pre-paid packaging to return it. Upon receipt, Fitbit will issue a refund of $299 plus a…

The new fine-pitch 9155-020 Series board-to-board battery connectors complete the 9155 Series product family and further establish KYOCERA AVX’s well-proven battery connector portfolio as the broadest selection of standard battery…
