In a new study, researchers made a cathode, or the positive end of a battery, in the shape of a thread-like fiber. The researchers were then able to use the fiber to create a zinc-ion battery prototype that could power a wrist watch.

Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural 'green' materials. A team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.

The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.

Solid-state Lithium-Sulfur batteries offer the potential for much higher energy densities and increased safety, compared to conventional lithium-ion batteries. However, the performance of solid-state batteries is currently lacking, with slow charging and discharging being one of the primary causes. Now, a new study shows that sluggish lithium ion transport within a composite cathode is the cause of this slow charging and discharging.
