The proposed approach allows precise and independent control of average composition, slope, and curvature of full concentration gradients in high-nickel cathodes, resulting in lithium-ion batteries ...

Chemists have studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings demonstrated that the valence gradient can ...
