Battery interface design

For readers

This page is a query-first entry point for battery interface design questions in this knowledge base. It maps common design intents to corpus-backed starting papers, synthesis hubs, and method/debate pages, without claiming coverage beyond the indexed corpus.

Scope and user intent

This entry point helps with questions such as: Which interface chemistry risks should I model first? Should I start from ceramic electrolyte transport, liquid-electrolyte decomposition, or Si-anode interfacial degradation? Where does ReaxFF help, and where do transferability risks dominate?

Out of scope: universal design rules for all battery chemistries, quantitative ranking across papers with incompatible conditions, and claims not traceable to source_refs and linked paper pages.

Start-here pathways

• If your intent is solid electrolyte interface transport and composition effects, start at 2018shin-physical-che-development-reaxff, then batteries-interfaces-reaxff, and branch to theme-oxides-silica-ceramics for broader oxide context.
• If your intent is liquid-electrolyte decomposition near Li metal, start at 2020hossain-j-chem-phys-lithium-electrolyte-solvation, then read batteries-interfaces-reaxff and transferability-reactive-ff before extending chemistry.
• If your intent is anode-side interface degradation and morphology coupling, start at 2025carl-erik-l-foss-j-phys-chem-revisiting-mechanism, then compare assumptions against reaxff-parameterization-workflow and transferability-reactive-ff.
• If your intent is method-selection under cost versus fidelity constraints, start at reaxff-vs-mlip-accuracy, then connect to theme-ml-atomistic-potentials and theme-reactive-md-corpus.

Decision levers and trade-offs

• Chemistry coverage versus confidence: wider reactive coverage is useful only when relevant reaction classes were represented in training and validation.
• Phase specificity: parameter sets that behave well in one phase or composition window may fail when transferred to different interfacial environments.
• Interpretability versus peak accuracy: ReaxFF often supports broader long-timescale reactive exploration, while MLIPs can deliver higher local fidelity on tightly defined manifolds.
• Design-stage objective: screening mechanisms, testing transfer hypotheses, and targeting deployable process windows require different validation depth.

Canonical starting papers

• 2018shin-physical-che-development-reaxff - Start here for composition-dependent Li transport framing in ceramic electrolyte environments.
• 2020hossain-j-chem-phys-lithium-electrolyte-solvation - Start here for liquid carbonate decomposition logic and Li speciation-sensitive reactivity.
• 2025carl-erik-l-foss-j-phys-chem-revisiting-mechanism - Start here for interface-linked Si anode degradation narratives tied to reactive modeling.

Related protocols and debates

• Protocol: reaxff-parameterization-workflow for scoping, training-set design, and validation checkpoints before claiming predictive interface behavior.
• Debate: transferability-reactive-ff for phase and chemistry transfer limits that directly affect interface design confidence.
• Debate: reaxff-vs-mlip-accuracy for deciding when broad reactivity coverage or higher local accuracy is the dominant need.
• Theme context: batteries-interfaces-reaxff, theme-reactive-md-corpus, and theme-ml-atomistic-potentials.

Failure modes and interpretation pitfalls

• Treating a successful fit in one electrolyte or phase as evidence of broad transferability without targeted validation.
• Over-reading mechanism detail when extraction quality is partial or when papers emphasize trends over exhaustive species-level assignments.
• Comparing rate or stability trends across papers without normalizing for temperature window, composition, and boundary-condition differences.
• Conflating corpus gaps with scientific impossibility; missing coverage in this KB should trigger new curation links, not hard claims.
