The clean energy revolution requires a lot of batteries. While lithium-ion dominates today, researchers are on a quest for better materials.

Redwood Materials is taking depreciated but still functional EV batteries and turning them into low-cost energy storage units.

Solid-state batteries have long been elusive, but a firm that supplied cells to the Defense Department could be first to get them into consumer electronics.

Interstate Batteries, on the other hand, suggests that it might take eight hours of highway driving to charge a depleted battery to nearly full.

Everstart batteries are among the most budget-friendly batteries on the market, but users reviews of the Walmart-sold batteries are incredibly mixed.

Sodium-ion batteries are popping up in electric scooters and grid storage installations.

Inlyte Energy is reviving and scaling iron-sodium battery technology to create a safe, low-cost, and domestically sourced alternative to lithium-ion batteries for utility-scale storage.

There are seven sizes of car batteries, and in each size there's a best one, according to Consumer Reports' testing. Here are the tops in each category.

The overall structure of a solid-state battery is quite similar to that of traditional lithium-ion batteries otherwise, but without the need for a liquid, the batteries can be much denser and compact.

CATL, the world’s largest maker of batteries for electric vehicles, described breakthroughs that could make E.V.s more competitive with gasoline-powered cars.

Solid-state batteries offer a number of benefits for boaters, including lighter weight and increased capacity. Find out how to choose the right one for you.

Inlyte’s sodium-iron battery tech offers a safer, cheaper, and longer-lasting alternative to lithium-ion for long-duration energy storage. Production starts soon.
