Abstract
Operando measurement of expansion force becomes effective to monitor physical-chemical events in lithium-ion batteries, of which the conventional optical means is limited by material fragility, structural incompatibility, and system complexity. The utilization of flexible sensors can potentially address these challenges; however, their functionality and stability are restricted within hours under the corrosive environments. Here, an in-situ unified iontronic sensing mechanism, derived from super-capacitive electrode/electrolyte interface, is developed for expansion-force measurement in the highly corrosive electrolyte environments. Specifically, it leverages the structural and material similarities between batteries and iontronic sensors to create the unified assessing device utilizing only the existing materials to form the in-situ detection. Consequently, the intelligence-incorporated architecture exhibits exceptional stability for continuous measurements over one month, enabling 400 charging/discharging cycles for battery lifespan. Therefore, the UIS device with long-term on-board monitoring of expansion forces offers an accurate and effective solution to the aging evaluation and safety warning of LIBs.

Accepted manuscripts
Accepted manuscripts are PDF versions of the author’s final manuscript, as accepted for publication by the journal but prior to copyediting or typesetting. They can be cited using the author(s), article title, journal title, year of online publication, and DOI. They will be replaced by the final typeset articles, which may therefore contain changes. The DOI will remain the same throughout.
This content is only available as a PDF.
