What is the design strategy for relay catalyst in lithium-sulfur (Li-S) batteries?

A design strategy for relay catalyst in lithium-sulfur (Li-S) batteries is proposed, where different components of the relay catalyst promote conversion at distinct catalytic stages.

What is a lithium based battery?

Lithium (Li)-based batteries, particularly Li-ion batteries, have dominated the market of portable energy storage devices for decades.

Are lithium-ion batteries safe?

In the rapidly evolving domain of energy storage, lithium-ion batteries have emerged as pivotal components powering everything from portable electronics to electric vehicles. Yet, despite their widespread adoption and remarkable energy density, safety and longevity continue to pose significant challenges.

Are relay catalysts suitable for Li-S batteries?

In contrast, relay catalysts facilitate a strong adsorption stage during the catalytic process, which not only enhances the adsorption of LiPSs onto the catalytic sites but also improves the catalytic conversion to Li 2 S following adsorption (Fig. 1c). Currently, there is no separator specifically designed for Li-S batteries.

Could a new solvent-relay strategy improve lithium-ion battery life?

Addressing these issues head-on, a recent groundbreaking study has revealed a novel solvent-relay strategy, promising not only enhanced thermal stability but also prolonged cycle life in high-voltage lithium-ion batteries.
