Through the imaging and visualization of the electron orbit, its characteristics and symmetry are determined

【introduction】

Nowadays, the electrification of heavy transportation and aerospace has put forward higher requirements for the increase of the energy density of electrode materials in batteries
.

【Introduction to Achievements】

In view of this, Los Alamos National Laboratory Hasnain Hafiz, Northeastern University’s Arun Bansil, and Carnegie Mellon University’s Venkatasubramanian Viswanathan (co-corresponding author) and others have collaborated on the high-energy X-ray Compton measurement method and the first The combination of sexual principle modeling shows that the electron orbital that plays a key role in the reversible stabilization of anion redox activity can be imaged and visualized, and its characteristics and symmetry can be determined from this
