2018 journal article

Operando Atomic Force Microscopy Reveals Mechanics of Structural Water Driven Battery-to-Pseudocapacitor Transition

ACS NANO, 12(6), 6032–6039.

By: R. Wang n, J. Mitchell n, Q. Gao *, W. Tsai *, S. Boyd n, M. Pharr *, N. Balke* , V. Augustyn n

Contributors: R. Wang n, J. Mitchell n, Q. Gao *, W. Tsai *, S. Boyd n, M. Pharr *, N. Balke* , V. Augustyn n

author keywords: atomic force microscopy; interlayer engineering; nanoconfined water; energy storage; transition metal oxides
TL;DR: The local mechanical deformation of the hydrated tungsten oxide is smaller and more gradual than the anhydrous oxide and occurs without hysteresis during the intercalation and deintercalation processes, suggesting the ability of layered materials with confined structural water to minimize mechanicalDeformation likely contributes to their fast energy storage kinetics.
