  • A dynamic interconversion of three nickel states in lithium nickel oxide is demonstrated using evidence from x-ray spectroscopic data and first-principles calculations, which explains many physical properties of this and similar materials.

  • Solid-state ionic conduction is a key enabler of electrochemical energy storage and conversion. A quantitative framework for ionic conduction between atomistic and macroscopic timescales in β- and β″-aluminas is now proposed for ‘atoms-to-device’ multiscale modelling and optimization.

  • Single-cycle terahertz pumps are used to impulsively trigger ionic hopping in battery solid electrolytes, probing ion transport at its fastest limit and demonstrating the connection between activated transport and the thermodynamics of information.

  • Electrochemical ion insertion is rapidly emerging as a powerful materials design strategy. This Review discusses how ion insertion enables reversible transformation and switching of physico-chemical properties, the role of defects and interfacial reactions, and opportunities for ultrafast ionic control.
