Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Background:

Ultrahigh-nickel, cobalt-free layered cathodes are sought for high-capacity, low-cost, and eco-friendly lithium-ion batteries.
Challenges include managing nickel/manganese magnetic moments and Ni³⁺ instability, hindering widespread adoption.

Purpose of the Study:

To develop an ultrastable single-crystal ultrahigh-nickel, cobalt-free cathode.
To enhance electrochemical performance and material cost-effectiveness.

Main Methods:

A three-in-one strategy incorporating internal aluminum (Al) and external zirconium (Zr) was employed.
The resulting cathode material is Li(Ni₀.₉₀Mn₀.₀₈Al₀.₀₂)₀.₉₈Zr₀.₀₂O₂ (NMAZ).

Main Results:

NMAZ demonstrated prevention of high-spin Ni³⁺ formation by AlO₆ ligands and restricted Ni diffusion by surface-enriched Zr.
The single-crystal structure minimized electrolyte reactions, leading to >7.5% cost reduction compared to conventional cobalt-containing NMC.
Excellent calendar lifespan, phase stability, and alleviation of H2-H3 phase transformation were observed.

Conclusions:

The NMAZ cathode achieves a balance of low cost and high electrochemical performance.
This material offers superior stability and lifespan, addressing key limitations in current lithium-ion battery technology.
