Rechargeable batteries that use ammonium cations as charge carriers could provide ecofriendly and sustainable substitutes to metal-ion-based batteries, researchers at KAUST show.
Metal-ion batteries, such as lithium-ion batteries, are the go-to energy storage solution. They dominate the market for portable consumer electronics and electric vehicles because of their high energy density and versatility. However, metal ions used in the…
