Legacy production line upgrade to solid-state
No teardown, no rebuild
Field-driven solid-state battery technology output, is how QuanVol turns the field-driven solid-state battery platform into an executable production line upgrade plan, delivered to cell or battery makers that already operate a lithium battery line, so that they can Keep the existing production line while upgrading to a solid-state or semi-solid-state system.
What we sell is not a drawing, but a complete plan for how the line changes
An existing liquid-electrolyte lithium battery line only needs to switch Field-driven functional coating separatorplus matching electrolyteComposite solid-state electrolyte, and complete Light equipment modification, you can convert it into a solid-state line.No new plant, no teardown or rebuild.Retrofit scope, process parameters, validation criteria and quality standard are all delivered by QuanVol.
Technology output deliverables
Seven deliverables, from the line inventory all the way to staff training and on-site support through trial production. What we deliver is executable action, not a concept document.
01 · Line fit assessment
Inventory of the current line conditions (coating, winding, stacking, filling, formation) to define the retrofit scope.
02 · Material matching plan
Matches field-driven coated separator and composite solid-state electrolyte specifications to the customer target chemistry.
03 · Process parameter package
The key process parameters and operating windows that match the field-driven material system.
04 · Retrofit proposal
Parts to be replaced, the light equipment modification list, construction sequence and downtime schedule.
05 · Validation and data alignment
Half-cell and full-cell validation plans with performance and safety test items and pass criteria.
06 · Quality system and certification
Process control points built to the QuanVol quality standard, covered by QuanVol Inside certification.
07 · Training and on-site support
Operating and process training, plus on-site support through trial production.
08 · Ongoing service
Ongoing material supply, process optimization and product iteration support.
What level you reach after the upgrade
Below are the capability ranges QuanVol has measured. For your line and model, the joint validation data governs.
| Dimension | Capability range | Test basis |
|---|---|---|
| Safety performance | No fire, no explosion under nail penetration | Nail penetration test per national standard |
| Operating temperature range | −40℃ ~ 80℃ | Verified by high and low temperature testing |
| NCM system cycling | 3,000 cycles with 80% capacity retention | Pilot-scale batch data |
| LFP system cycling | Stable cycling beyond 8,000 cycles | Pilot-scale batch data |
| Retrofit scope | Existing line retained, new materials plus light equipment modification | Production line fit assessment |
The above are capability ranges measured in the QuanVol system and vary by product line and model. Any external citation must state the model and test conditions, and the joint validation conclusion governs.
Who technology output is for
| Customer types | Typical pain points | Where QuanVol comes in |
|---|---|---|
| Existing liquid-electrolyte battery plants (has production lines, lacks a solid-state plan) |
Wants solid-state but a new line means heavy investment and long timelines | Light retrofit: a solid-state upgrade path for existing lines with no new plant |
| Semi-solid and solid-state line operators (stuck on interface and yield) |
Interface impedance, ionic conductivity, cycle fade | Field-driven interface plan plus material matching, open to joint validation |
| Regional battery plants / local industrial projects | Needs a solid-state technology plan and industrial upgrade path that can actually land | An integrated delivery of plan, matching materials and certification |
| Industry investors / industrial parks | Needs a workable judgment on the solid-state technology route | Technology platform overview plus feasibility (no project-specific commercial details) |
How cooperation works
Seven stages, from first contact to ongoing service. The early stages run the fit assessment and joint validation so you can confirm with your own line and data.
Technology output FAQ
What exactly does technology output deliver?
a complete production line upgrade plan: line fit assessment, material matching plan, process parameter package, retrofit proposal, validation plan, quality system and certification, staff training and on-site support through trial production. What we deliver is executable action, not a concept document.
How much does my existing liquid-electrolyte line need to change?
The main line is retained. The core actions are switching to the field-driven coated separator, adding the matching composite solid-state electrolyte and making light equipment modifications. The exact scope requires a line fit assessment first, confirmed against your line conditions.
What performance level after the upgrade?
On safety, no fire and no explosion under nail penetration; operating range −40°C to 80°C; on cycling, 3,000 cycles at 80% retention for NCM and beyond 8,000 cycles for LFP. These are capability ranges measured in the QuanVol system; for your line and model, the joint validation data governs.
How long does it take?
It depends on the line condition and retrofit scope; the assessment stage gives you a clear schedule. We do not promise lead times beyond the actual schedule.
Is your technology your own?
It is our own technology platform. QuanVol owns the technology route, material system, process and quality standard for the field-driven solid-state battery, and the measured data comes from validating the QuanVol system. For technical detail, see the technology platform and measured data pages.
How do you quote?
Pricing is quoted per project and volume, and is not disclosed through public channels. Send us your line scale, target chemistry, upgrade scope and schedule, and the commercial proposal will include the quotation.
Can we start with a small-scale validation?
Yes. Before anything is committed we run a fit assessment and joint validation so you can confirm with your own line and data, which is more reliable than reviewing materials alone.
Want to assess the solid-state path for your line?
Send us your line type, target chemistry, upgrade scope and schedule. QuanVol issues a line fit assessment first, defining the retrofit scope and feasible path.
