AI for High-Voltage Electrolytes

High-Voltage Electrolytes Development Services

Extend the practical voltage window by designing the electrolyte and cathode interface together. CD ComputaBio applies AI, molecular simulation, quantum chemistry, and mechanism-based analysis to prioritize oxidation-resistant solvents, salts, and CEI-forming additives for high-voltage battery systems.

What CD ComputaBio Can Do

High-voltage electrolyte development services

From candidate screening and cathode-surface modeling to CEI interpretation and failure-data analysis, our services are organized around the formulation decision you need to make next.

High-Voltage Molecule Screening

Rank solvents, co-solvents, salts, and additives by redox descriptors, physicochemical properties, structural alerts, and constraints.

Cathode Surface and Adsorption Modeling

Compare molecular orientation, binding, competitive adsorption, and surface-dependent reactivity on relevant facets or coatings.

Oxidation and Decomposition Pathways

Evaluate electron-transfer tendencies, bond cleavage, radical intermediates, gas-forming routes, and product energetics.

CEI Product Assessment

Interpret expected organic/inorganic film components, passivation potential, ionic transport, and chemical durability.

Solvation and Concentration Effects

Use molecular dynamics to analyze coordination, free-solvent activity, ion clusters, transport, and temperature response.

Failure-Data Interpretation

Connect EIS, gas, cycling, XPS, ICP, NMR, and other measurements with molecular and interfacial mechanisms.

The Real Design Challenge

A high oxidation score alone does not create a durable electrolyte

At elevated cathode potentials, solvent and salt oxidation can trigger gas generation, resistive CEI growth, transition-metal dissolution, surface reconstruction, electrolyte consumption, and impedance rise. These processes are coupled and may change with temperature, state of charge, trace water, formation protocol, and cathode surface chemistry.

Our workflow focuses on the complete failure chain: which species reacts first, what products are likely to form, whether those products protect or damage the interface, and which formulation changes are worth testing.

Molecular Oxidation

Identify solvents, anions, impurities, and additives most susceptible to electron removal or bond cleavage.

Interfacial Reaction

Assess adsorption, competitive decomposition, catalytic cathode surfaces, and reaction energetics.

CEI Quality

Estimate whether products support passivation, ionic transport, mechanical integrity, and low impedance.

Cell-Level Consequences

Connect reaction hypotheses with gas, impedance, metal dissolution, capacity fade, and cycling behavior.

High-Voltage Failure Map

Target the failure mode before choosing the additive

Different bottlenecks require different molecular and interfacial design strategies.

O₂

Electrolyte Oxidation and Gas

Screen oxidation-sensitive species and plausible pathways leading to CO₂, CO, oligomers, or other volatile products.

CEI

Unstable Cathode Interphase

Compare additives and anions that may form dense, ion-conductive, electronically insulating surface films.

Transition-Metal Dissolution

Assess acid-forming pathways, anion decomposition, metal coordination, and chelating or scavenging strategies.

Impedance Growth

Link excessive interphase formation, salt depletion, poor wetting, or unstable products with transport limitations.

Mechanism-Guided Design

Map candidate molecules onto the reaction pathway

Rather than ranking molecules only by a calculated oxidation potential, we evaluate how the molecule interacts with the charged cathode surface and what happens after the first electron-transfer or bond-breaking event.

Initiation: redox tendency, adsorption, orbital alignment, and catalytic surface effects.

Propagation: bond cleavage, radical reactions, oligomerization, gas generation, and salt coupling.

Products: predicted inorganic/organic components, film stability, and metal coordination.

Outcome: protective passivation versus continuous electrolyte consumption and impedance growth.

Design Strategy Matrix

Choose formulation levers according to the dominant risk

Each strategy is evaluated for both intended function and possible side effects.

Solvent Design

Increase Intrinsic Oxidation Resistance

Compare fluorinated, sulfone, nitrile, phosphate, ionic-liquid, or other solvent families while retaining transport and wetting.

Salt Chemistry

Control Anion-Derived Interphase

Evaluate anion stability, coordination, decomposition products, aluminum corrosion risk, and concentration effects.

Additive Design

Form a Protective CEI First

Prioritize sacrificial oxidation, surface affinity, product stability, and low loading requirements.

Concentration

Reshape the Solvation Environment

Assess contact ion pairs, aggregates, reduced free solvent activity, viscosity, and salt-consumption trade-offs.

Interface Control

Coordinate Electrolyte and Coating

Study compatibility with cathode coatings, dopants, surface reconstruction, and formation conditions.

Data-Driven Optimization

Learn from Cycling and Analytics

Fuse formulation, electrochemistry, gas, spectroscopy, and impedance data to identify performance drivers.

Frequently Asked Questions

Planning a high-voltage electrolyte study

What upper cutoff voltage can be modeled?

The workflow is defined by the specific cathode, surface state, electrolyte composition, and target operating conditions rather than by one universal voltage threshold. The project should specify the intended cutoff and relevant reference electrode.

Can you compare additives for both CEI formation and gas risk?

Yes. Candidate additives can be assessed for oxidation tendency, adsorption, decomposition products, gas-forming pathways, and whether the expected products are consistent with protective or resistive interphase growth.

Can cathode coatings or dopants be included?

Yes. Surface coatings, doped surfaces, reconstructed layers, or representative facets can be incorporated when structural information and project scope support meaningful comparison.

How are experimental failure data used?

Electrochemical and analytical observations are used to constrain likely mechanisms, prioritize calculations, and distinguish between competing explanations such as solvent oxidation, salt decomposition, metal dissolution, or excessive film growth.
