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.
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.
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.
Target the failure mode before choosing the additive
Different bottlenecks require different molecular and interfacial design strategies.
Electrolyte Oxidation and Gas
Screen oxidation-sensitive species and plausible pathways leading to CO₂, CO, oligomers, or other volatile products.
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.
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.
Choose formulation levers according to the dominant risk
Each strategy is evaluated for both intended function and possible side effects.
Increase Intrinsic Oxidation Resistance
Compare fluorinated, sulfone, nitrile, phosphate, ionic-liquid, or other solvent families while retaining transport and wetting.
Control Anion-Derived Interphase
Evaluate anion stability, coordination, decomposition products, aluminum corrosion risk, and concentration effects.
Form a Protective CEI First
Prioritize sacrificial oxidation, surface affinity, product stability, and low loading requirements.
Reshape the Solvation Environment
Assess contact ion pairs, aggregates, reduced free solvent activity, viscosity, and salt-consumption trade-offs.
Coordinate Electrolyte and Coating
Study compatibility with cathode coatings, dopants, surface reconstruction, and formation conditions.
Learn from Cycling and Analytics
Fuse formulation, electrochemistry, gas, spectroscopy, and impedance data to identify performance drivers.
From high-voltage failure signature to formulation recommendation
Define the Voltage Problem
Specify cathode, upper cutoff, anode, temperature, formation protocol, baseline electrolyte, and observed failure.
Build the Reaction Space
Curate candidate molecules, surfaces, impurities, coatings, and plausible decomposition routes.

Deliver ranked formulations, controls, analytical readouts, and clear go/no-go criteria.
Decision-ready outputs for high-voltage electrolyte programs
Deliverables are configured around the client's voltage target, failure mode, data availability, and experimental capacity.
Candidate Ranking
Prioritized solvents, salts, additives, and composition ranges with trade-off analysis.
Reaction and CEI Map
Likely oxidation pathways, intermediates, gas routes, products, and passivation hypotheses.
Structure and Simulation Data
Optimized structures, surfaces, trajectories, energies, descriptors, figures, and calculation records.
Experimental Validation Plan
Recommended formulations, controls, electrochemical tests, analytics, and decision thresholds.
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.
