2023 energy storage negative electrode materials

Are metal negative electrodes reversible in lithium ion batteries?

Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.

Are metal negative electrodes suitable for high energy rechargeable batteries?

Nature Communications 14, Article number: 3975 (2023) Cite this article Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries.

Are aluminum-based negative electrodes suitable for high-energy-density lithium-ion batteries?

Aluminum-based negative electrodes could enable high-energy-density batteries, but their charge storage performance is limited. Here, the authors show that dense aluminum electrodes with controlled microstructure exhibit long-term cycling stability in all-solid-state lithium-ion batteries.

Is hard carbon a negative electrode material for Na-ion batteries?

Hard carbon (HC) is a promising negative-electrode material for Na-ion batteries. HC electrochemically stores Na + ions, resulting in a non-stoichiometric chemical composition depending on their nanoscale structure, including the carbon framework, and interstitial pores.

Can aluminum-based negative electrodes improve all-solid-state batteries?

These results demonstrate the possibility of improved all-solid-state batteries via metallurgical design of negative electrodes while simplifying manufacturing processes. Aluminum-based negative electrodes could enable high-energy-density batteries, but their charge storage performance is limited.

Are lithium metal negative electrodes suitable for SSBs?

Lithium metal negative electrodes have been extensively investigated for SSBs because of their low electrode potential and high theoretical capacity (3861 mAh g −1) 1. However, challenges associated with interfacial instabilities and lithium filament penetration to cause short-circuiting have proven extremely difficult to solve 1, 2, 3, 4.
