Surface Plasmon Resonance in Layer-by-Layer Biosorbent Electrodes for Energy Storage

PROBLEM: Energy-storage electrodes do not normally need an optical readout, yet a plasmonic layer in an LbL electrode could in principle report ion binding at the interface during cycling — if the metal–dielectric structure survives charge and discharge and the biosorbent layers do not block the field. An electrode design that adds a plasmonic layer without a versioned record of its placement and regeneration history cannot be reproduced or compared across batches.

SOLUTION: Storage Copy Data Management would preserve versioned copies of each plasmon-enhanced LbL electrode design, linking the plasmonic layer placement to its DFT prediction, its isotherm validation, and its cycling and regeneration record. The capability would support reproducibility checks and retention so a storage result can be traced to the exact electrode version that produced it.

EVIDENCE BASIS: DOCUMENTED — surface plasmon resonance is collective electron oscillation at metal–dielectric interfaces, with field enhancement for sensing; layer-by-layer assembly alternates polyelectrolyte and biomass layers at room temperature in water; DFT predicts which surface groups bind which metal ions; biosorption follows Langmuir and Freundlich isotherms.
