The choice between water-based and NMP-based conductive slurry depends on battery chemistry, process route, rheology requirements, and how closely the slurry format matches the intended manufacturing workflow.
Water-based slurry is often the better first step when the target system is LFP, ESS, or another aqueous-process route.
NMP-based slurry is often the better first step when the target is high-Ni cathodes, silicon-graphite anodes, or other NMP-based evaluation workflows.
The right decision depends on chemistry, process compatibility, and what the team wants to validate first.
The solvent route changes process handling and compatibility from the beginning of evaluation.
Rheology and handling behavior matter in both routes, but they are assessed in different formulation and process environments.
Water-based and NMP-based systems are usually not interchangeable first-choice routes because they serve different formulation and manufacturing contexts.
| Evaluation factor | Water-Based Conductive Slurry | NMP-Based Conductive Slurry |
|---|---|---|
| Solvent route | Water-based route. | NMP-based route. |
| Typical best-fit chemistry | LFP, ESS, and other aqueous-process systems. | High-Ni cathodes, silicon-graphite anodes, and other NMP-based systems. |
| Best-fit workflow | Aqueous formulation and process-fit evaluation. | Performance-oriented or manufacturing-compatible NMP workflow evaluation. |
| Process-fit priority | Fit with water-based electrode systems and aqueous handling. | Fit with existing NMP-based workflows and manufacturing logic. |
| Rheology / handling focus | Water-based rheology, pseudoplastic and thixotropic behavior, storage and process flow. | NMP-route dispersion consistency, process handling, and workflow compatibility. |
| Representative product route | TYBH | TY-70C / TY-82EC |
| Main engineering question | Does the water-based route fit the chemistry and process window? | Which NMP-based route best fits the performance or manufacturing objective? |
| Where it is often evaluated first | LFP, ESS, and aqueous-process screening. | High-Ni, silicon-graphite, fast-charging, and existing NMP workflow screening. |
1. Process compatibility
Confirm fit with the actual solvent route and process environment.
2. Rheology / handling window
Review whether the slurry stays workable in the intended process window.
3. Dispersion stability
Check whether the route remains stable enough for a meaningful first screen.
4. Fit with target battery chemistry
Keep chemistry fit central to the first decision, not only the product format.
5. Coating and transfer behavior
Review whether the slurry behaves acceptably during transfer and coating steps.
6. Comparison against current conductive-additive route
Keep the current conductive-additive baseline visible so the outcome stays commercially useful.
Use TYBH when aqueous-process fit, LFP, or ESS is the main context.
Use TY-70C when high-performance screening is the first NMP-based question.
Use TY-82EC when NMP workflow compatibility and stability matter early.
Use the application page when aqueous storage-oriented systems are central.
Open the application page when nickel-rich cathodes drive the route decision.
Open the page when silicon-related network stability drives the NMP route choice.
Use the guide when the next decision is which SWCNT route deserves screening first.
Use the page when product form is the next screening question.
The main difference is the process environment they are built to fit. Water-based routes serve aqueous formulation and handling workflows, while NMP-based routes serve NMP-based process environments used in different battery chemistries and evaluation paths.
Engineers should evaluate water-based slurry first when the target system is LFP, ESS, or another aqueous-process route where water-based rheology, handling, and process fit are the main questions.
NMP-based slurry is often the better first route when the target system is high-Ni cathodes, silicon-graphite anodes, fast-charging-related development, or an existing NMP-based manufacturing workflow.
Based on the visible site positioning, water-based conductive slurry is especially relevant for LFP, ESS, and other aqueous-process evaluation routes.
Start with process compatibility, rheology and handling window, dispersion stability, fit with target battery chemistry, coating and transfer behavior, and comparison against the current conductive-additive route.
Share the chemistry, the solvent route, and whether the first goal is aqueous process fit, performance-oriented screening, or manufacturing-compatible evaluation. That is usually enough to define the most useful first route.
