A flexible lithium-ion battery designed by a team of researchers from the Johns Hopkins Applied Physics Laboratory and built to operate under extreme conditions—including cutting, submersion, and simulated ballistic impact—can now add incombustible to its résumé.

The growing popularity of lithium-ion batteries in recent years has put a strain on the world's supply of cobalt and nickel—two metals integral to current battery designs—and sent prices surging.

Power on the go is in demand: The higher the battery capacity, the larger the range of electric cars and the longer the operating time of cell phones and laptops. Dr. Jennifer Ludwig of the Technical University of Munich (TUM) has developed a process that allows a fast, simple, and cost-effective pr......

Li-ion batteries (LIBs) are advantageous energy storage devices due to their higher specific energy density, lower self-discharge, and lower memory effect. Among the components of batteries, electrode materials play a key role in enhancing electrochemical properties.

Although most of our electronic devices, like mobile phones, laptops and electric vehicles use lithium rechargeable batteries, what is going on inside them is not fully understood

A new approach developed by a team of researchers, led by Prof. Jaephil Cho (School of Energy and Chemical Engineering) could hold the key to greatly improving the performance of commercial lithium-ion batteries.
