So much of focus from researchers in lithium battery circles rests centers on the electrodes. Among them are scientists at Carnegie Mellon University, who have come up with a new way of 3D printing latticed electrodes they say result in an "unprecedented improvement."

Researchers have found that materials known as niobium tungsten oxides form microscopic structures that let lithium ions flow through them at much greater rates than current technology allows. The finding could be the key to building safe lithium-ion cells that charge in minutes rather than hours.

Striking a balance between common materials and efficiency is important for batteries, and regular old salt looks like it could fit the bill – after a few kinks are ironed out. Now, KAUST researchers have developed a way to make disordered graphene that can improve the sodium-ion battery recipe.

Flow batteries have the potential to help store energy on a large scale, but there are a few issues still to overcome. Stanford engineers have developed a new type of flow battery that might be scalable, safe, efficient and inexpensive, using a metal mixture that remains liquid at room temperature.

Nuclear batteries can last decades, but their power density is currently too low to be very practical. Now, Russian researchers have developed a new nuclear battery design based on nickel-63, which has a higher specific energy than regular, commercially-available batteries.

After a few weeks with the SwitchCharge, a beefy battery pack for the Nintendo Switch, we’re happy to report that it actively solves some of Nintendo’s niggles, earning its place in our bag basically every time we leave the house with the Switch.

Most batteries have a cathode on one side and an anode on the other, with a separator between them. Engineers at Cornell University have developed an unusual new structure that intertwines the components together in a swirling shape, which they say lets the device recharge in a matter of seconds.
