Full-domain solid-state safe battery supplier
Making safety the default in batteries
Shenzhen QuanVol Technology Co., Ltd. was founded by Wen Jianchao, an investor with deep roots in the solid-state battery industry. QuanVol takes the field-driven solid-state battery technology system as its core capability and is supported by proprietary field-driven functional coating separators and composite solid-state electrolyte materials, building a complete technology chain from materials to solid-state battery products.

What QuanVol does and does not do
What we do
Product definition, technical planning and supply of solid-state batteries: from selection, sampling and validation to volume delivery and after-sales; development and supply of the field-driven coated separator and composite solid-state electrolyte; field-driven solid-state battery technology output including legacy line solid-state upgrade plans; unified product standards, quality control and QuanVol Inside certification; joint product definition and application fit for end users.
What we do not do
No retail and no direct sales to individual consumers; B2B only. No disclosure of prices, quotations, or costs through any public channel. No claims of partnerships with universities or research institutes, and no use of their results as endorsements. No fabricated production assets and no commitments to capacity or lead times we cannot deliver.
Four business lines on one technology platform
| Business lines | Scope | Entry point |
|---|---|---|
| Solid-state battery product sales | Solid-state cell supply for every application, with seven product lines shipping from stock plus custom development | Product lines → |
| Field-driven coated separator sales | The field-driven coated separator is sold externally and fits liquid, hybrid and solid-state lines with only light equipment modification | Materials business → |
| Composite solid-state electrolyte sales | The composite solid-state electrolyte is sold externally and is not tied to a single oxide, sulfide or polymer route | Materials business → |
| Field-driven solid-state battery technology output | Turns the technology platform into an executable production line upgrade plan, including legacy line solid-state upgrades | Technology output → |
All four business lines share one field-driven solid-state battery technology platform. Cell makers with a lithium battery line considering solid-state can start from material sampling or a line fit assessment; see Cell-maker partnership。
field-driven solid-state battery
one chain from material to cell
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.
The system is not tied to a single electrolyte route, and can be layered onto liquid, hybrid liquid-solid, and solid-state production lines for upgrading. QuanVol independently controls the two key material products, field-driven functional coating separators and composite solid-state electrolytes. These are both the source of product performance and what QuanVol is really built on.
Learn more about the technology systemOur three principles
Safety is the starting point, not a selling point
Intrinsic safety is written into the starting point of the technology roadmap: no fire and no explosion under nail penetration, and stable operation across a wide temperature range. Safety is not a paid option. It is the first standard every product must meet.
Data is model-specific, never one table for everything
3C consumer, drone, low-speed light electric vehicle, and energy storage lines have inherently different requirements for discharge rate, energy density, and cycle life. Any figure cited must state the model it applies to.
Service all the way through, so customers do not run around
Model selection, sampling, validation, volume delivery, and after-sales support are all handled by QuanVol from start to finish. Quality issues are led by QuanVol, so customers do not have to shuttle between suppliers themselves.
Seven product lines covering mainstream applications
| Product lines | Applications |
|---|---|
| 3C consumer battery | Consumer digital devices, portable power supplies, smart wearables, IoT devices, medical instruments |
| Drone battery | Industrial drones, agricultural spraying drones, surveying and aerial photography drones |
| Low-speed light electric vehicle battery | Two-wheelers, three-wheelers, high-speed electric motorcycles |
| Robot and AGV power battery | Service robots, AGV and AMR units, warehouse and logistics automation equipment |
| Premium power tool battery | Power tools, garden machinery |
| Energy storage battery | Commercial and industrial energy storage, residential energy storage |
| Standard cylindrical battery | Standard product replacement, model toys |
Product lines are organized by application and expand on a rolling basis with customer demand and new product validation. Each product line contains multiple specific models, and capacity, discharge rate, cycle life, temperature range, and dimensions are independent for each model. There is no single set of QuanVol parameters.
