Charging lithium-ion batteries (LIBs) in a fast and safe manner is critical for the widespread utility of the electric vehicles [1, 2, 3, 4, 5]. However, fast Li + intercalation in graphite is challenging due to its sluggish kinetics [6, 7, 8].
Graphite is presently the most common anode material for lithium-ion batteries, but the long diffusion distance of Li + limits its rate performance. Herein, to shorten the diffusion path, we develop a favorable electrode consisting of thin graphite sheets with through-holes and carbon nanotube.
Practical challenges and future directions in graphite anode summarized. Graphite has been a near-perfect and indisputable anode material in lithium-ion batteries, due to its high energy density, low embedded lithium potential, good stability, wide availability and cost-effectiveness.
Nature Energy 8, 1365–1374 (2023) Cite this article Li + desolvation in electrolytes and diffusion at the solid–electrolyte interphase (SEI) are two determining steps that restrict the fast charging of graphite-based lithium-ion batteries.
Fast-charging lithium-ion batteries are highly required, especially in reducing the mileage anxiety of the widespread electric vehicles. One of the biggest bottlenecks lies in the sluggish kinetics of the Li + intercalation into the graphite anode; slow intercalation will lead to lithium metal plating, severe side reactions, and safety concerns.
And because of its low de−/lithiation potential and specific capacity of 372 mAh g −1 (theory) , graphite-based anode material greatly improves the energy density of the battery. As early as 1976 , researchers began to study the reversible intercalation behavior of lithium ions in graphite.
