New work on fast-charging batteries has recently been reported by Zhang and colleagues. 93 This article focuses on the extremely fast charging of high energy LIBs by engineering the electrolyte to reduce the charge transfer energy barriers at both the anode and cathode.

Does space charge storage advance electrochemical energy storage?

This study demonstrates the critical role of the space charge storage mechanism in advancing electrochemical energy storage and provides an unconventional perspective for designing high-performance anode materials for lithium-ion batteries.

What is a fast-charging lithium-ion battery?

The work furnishes a theoretical basis for comprehending doping, nanosizing, and other modification methods. The fast-charging issue could be addressed from atomic and lattice scales. “Fast-charging” lithium-ion batteries enjoy extensive attention as energy storage devices for portable electronic devices and new energy vehicles.

Can fast-charging protocols improve the performance of electric vehicles and portable devices?

The development of fast-charging protocols for LIBs has become a key factor in enhancing the performance of electric vehicles and portable devices. Existing fast-charging protocols, such as CC-CV, MCC, and pulse charging strategies, have made notable progress in improving charging efficiency and reducing charging time.

How does fast charging work?

In the initial stage of fast charging, Li + ions are deinserted from the cathode while releasing electrons to the anode through an external circuit (Figure 1). 16 The extracted Li + ions cross the cathode–electrolyte interface (CEI) and are subsequently, solvated by the solvent molecules near the CEI.
