From passive diffusion
to active field-driven transport
Every QuanVol product is built on the same technology platform:field-driven solid-state battery technology system. It is not a substitute for any single class of electrolyte, but a cross-system ion transport enabling technology that can be layered onto liquid, hybrid liquid-solid, and solid-state production lines alike.
Technical definition (standard wording)
A field-driven solid-state battery is a solid-state battery system into which ferroelectric functional materials with spontaneous polarization are introduced. The built-in electric field they generate actively drives the rapid migration of lithium and sodium ions across electrodes, electrolytes, and interfaces, upgrading ion transport from passive diffusion to active field-driven movement.
How the built-in electric field drives ion migration
01 · Spontaneous polarization
Ferroelectric functional materials polarize spontaneously within the system, establishing a stable internal built-in electric field without any external power source.
02 · Active driving
The built-in electric field applies a directional force to lithium and sodium ions, actively driving them across electrodes, electrolytes, and interfaces.
03 · Interface optimization
Migration resistance falls and interfacial impedance decreases, releasing ion transport from the constraints of passive diffusion.
04 · Production line compatibility
Not tied to a single electrolyte route. Existing production lines need only a core material change and minor equipment modification to complete a solid-state upgrade.
How QuanVol technology is structured
| Technology system | The field-driven solid-state battery system, in which a built-in electric field generated by the spontaneous polarization of ferroelectric materials actively drives ion migration |
|---|---|
| Material system | Field-driven functional coating separator, composite solid-state electrolyte |
| Product and standards system | Product definition, sample validation, quality control, and QuanVol Inside certification |
The QuanVol technology system centers on field-driven ion transport and is supported by proprietary field-driven functional coating separators and composite solid-state electrolyte materials, forming a complete technology chain from materials to solid-state battery products.
Two key materials
are what QuanVol is really built on
Field-driven functional coating separator: relies on ferroelectric spontaneous polarization to form an intrinsic built-in electric field that actively drives efficient ion migration. Compatible with liquid, hybrid liquid-solid, and solid-state production lines, requiring only minor equipment modification.
Composite solid-state electrolyte: matches the field-driven interface system, is compatible with mass production processes, offers high stability and broad applicability, and is not tied to a single oxide, sulfide, or polymer route.
The technology is not only for internal use, it is delivered outward
The QuanVol field-driven technology platform opens two outward channels: supply you the materials, hand you the process.
Supply you the materials
The field-driven coated separator and composite solid-state electrolyte are supplied externally. An existing liquid-electrolyte line upgrades by switching materials with light equipment modification, with no new plant.
- Roll, powder or slurry, confirmed against your line specifications and process route
- Material-system-level data is available and open to sample validation
- One consistent quality specification, supplied to the same standard for the same spec
Hand you the process
Field-driven solid-state battery technology output turns the platform into an executable production line upgrade plan, delivered to cell or battery makers that already operate a lithium battery line.
- Line fit assessment + material matching plan + process parameter package
- Retrofit proposal plus validation and data alignment
- Staff training and on-site support through trial production

Product-level capability ranges
Capability ranges measured within the QuanVol system, not the datasheet of any single model| Parameter | Capability range | Test basis |
|---|---|---|
| Extreme stable operating range | -40℃ ~ 80℃ | Verified by high and low temperature testing |
| Safety nail penetration performance | No fire, no explosion under nail penetration | Nail penetration test per national standard |
| NCM system cycling | 3,000 cycles with 80% capacity retention | Pilot-scale batch data |
| LFP system cycling | More than 8,000 cycles | Pilot-scale batch data |
| Production line compatibility | Existing liquid production lines can be upgraded directly | Field-driven separator replacement plus matching solid-state electrolyte |
The values above are capability ranges measured within the QuanVol system, not the datasheet of any single model. Specific models across product lines (3C consumer, drone, low-speed light electric vehicle, and others) carry different values, and citations must state the model and test conditions.
An objective statement of maturity
The technology system, material system, and product system have been proven end to end. QuanVol is currently in the pilot-mature, batch-validation, and scaling-toward-mass-production stage. Long-cycle, vehicle-level validation on complete vehicles is a shared next step for the entire industry.
On the technology direction: using the built-in electric field generated by the spontaneous polarization of ferroelectric materials to regulate ion transport is one of the frontier directions in the solid-state battery field.
