Piezoelectric–Triboelectric Atomic Layer Deposition Electrodes for Energy Storage

PROBLEM: ALD coatings can protect energy-storage electrodes from side reactions, but they also add interfacial resistance and can alter strain-driven charge generation during cycling. An electrode that looks stable in early cycles may degrade once the coating cracks or the underlying biosorbent-derived layer swells. Without a governed record linking coating recipe, cycling history, and charge anomalies, failure analysis cannot distinguish coating failure from active-material loss.

SOLUTION: Storage Copy Data Management would provide a governed lifecycle capability that retains the ALD recipe, DFT-predicted interfacial behaviour, and measured cycling and charge-generation records for each electrode batch. The capability would version coating and regeneration histories together, preserve the energy budget for deposition and curing, and make the full lineage retrievable for audit. It manages the evidence rather than claiming a storage outcome.

EVIDENCE BASIS: Piezoelectric/triboelectric coupling is DOCUMENTED: mechanical strain or contact generates charge and is used in nanogenerators. DFT (Hohenberg–Kohn 1964, Kohn–Sham 1965, Nobel 1998) predicts surface binding and charge-transfer behaviour. Biosorption is validated via batch isotherms, qe = (C0 − Ce)V/m, with Langmuir and Freundlich isotherms as textbook models.
