Sodium-Ion Electrolyte Design Services

Design sodium-compatible electrolyte systems by connecting solvent and salt selection with Na+ solvation, ion transport, electrochemical stability, and electrode-specific interphase requirements. CD ComputaBio builds decision-focused computational workflows for hard-carbon, layered-oxide, Prussian blue analogue, polyanionic, and other sodium-ion battery chemistries.

Custom studies can begin from a formulation list, molecular library, cycling dataset, or a defined performance bottleneck.
Why Sodium Needs Its Own Design Logic

Do not treat sodium-ion electrolytes as lithium-ion formulations with a different salt

The larger ionic radius and different Lewis acidity of Na+ change coordination structure, desolvation, mobility, and interfacial reaction preferences. A solvent or additive that performs well in a lithium-ion cell may therefore produce weak transport, excessive gas, unstable cathode electrolyte interphase, or poor hard-carbon compatibility in a sodium-ion system.

Our studies translate these coupled effects into a ranked formulation strategy, with assumptions, uncertainty, and experimental validation priorities made explicit.

01TransportWhich solvent–salt combinations balance viscosity, dissociation, diffusivity, and Na+ transference?
02InterphaseWhich additives are likely to support stable SEI or CEI chemistry on the selected electrodes?
03Operating WindowHow will low temperature, high voltage, fast charge, or storage conditions change formulation ranking?
04Data UseHow can cycling, impedance, spectroscopy, and formulation records guide the next experimental round?

A single conductivity value is not enough

The most useful electrolyte is the one that satisfies the cell-level constraints together. We compare candidates across a transparent set of criteria rather than optimizing one descriptor in isolation.

Transport

Mobility under relevant conditions

Diffusion, association, viscosity-related descriptors, conductivity trends, and temperature response.

Stability

Electrochemical and thermal robustness

Oxidation/reduction susceptibility, decomposition pathways, gas-forming risk, and solvent–salt reactivity.

Interface

Electrode-specific reaction preference

Adsorption, early decomposition products, SEI/CEI hypotheses, and compatibility with coatings or binders.

Practicality

Formulation constraints

Concentration, miscibility, flash-point or safety considerations, cost boundaries, and available raw materials.

Integrated Computational Platform

Match the method to the sodium-ion question

Each modeling layer is selected according to the formulation decision, available evidence, and level of mechanistic resolution required.

Frequently Asked Questions

Planning a sodium-ion electrolyte project

Can a project start without a large proprietary dataset?

Yes. A study can begin from a defined molecular or formulation space, a literature-supported baseline, and clear cell constraints. The workflow can later incorporate proprietary cycling or characterization data as it becomes available.

Can you compare different sodium-ion electrode chemistries?

Yes. The electrolyte decision can be evaluated against the intended cathode and anode pair, including hard carbon, layered oxides, Prussian blue analogues, polyanionic materials, and other specified systems.

Do you predict absolute ionic conductivity?

The output depends on the available data and modeling level. We can calculate transport descriptors and trends, build calibrated predictive models when suitable reference data exist, and clearly distinguish calculated values from model-based estimates.

Can experimental results be used iteratively?

Yes. New cycling, impedance, spectroscopy, or physical-property measurements can be used to update ranking models and select the next formulations through an active-learning workflow.
