Juwan Technology recently put a GWh-class all-solid-state cell line into operation. The key point is not a brand-new gigafactory, but a retrofit of an existing 4GWh liquid lithium battery line. For overseas integrators, the signal is clear: solid-state manufacturing does not always require building from zero — mature liquid-cell lines can be upgraded through targeted process changes.
Third-Party Validation Comes Before Marketing Claims
The released all-solid-state cells were tested by a third-party laboratory using the newly published EV solid-state battery classification standard. A 44.5Ah cell was baked at 120℃ in a vacuum environment with an opened casing for 6 hours, showing a weight-loss rate below 0.5%. This is used to judge whether noticeable liquid electrolyte remains inside the cell.
On the safety side, a nail penetration test was performed on a fully charged cell. After a steel nail completely pierced the cell, there was no fire and no explosion, and the structure remained intact. For overseas buyers, nail test and thermal behavior often matter more than headline energy-density numbers because they affect transport, certification and pack design.
260–480Wh/kg With Stable Fast Charging
Juwan Technology reports single-cell specific energy from 260 to 480Wh/kg, cycle life comparable with conventional lithium cells, and stable fast-charge capability. If translated into modules, this affects:
size and weight of high-rate e-motorcycle or light commercial packs
energy density ceiling for residential and C&I storage
weight-sensitive applications such as low-altitude aircraft and robotics
Deep-Eutectic Route and In-Situ Curing Lower Retrofit Cost
Instead of the mainstream sulfide route, the company uses an ESC deep-eutectic composite solid electrolyte. The logic is simple: inject liquid precursor into the assembled cell, vacuum impregnate the electrodes, then cure in situ so the solid electrolyte forms inside the electrode pores. This reduces solid-solid interface resistance between prefabricated solid films and electrodes.
For manufacturing, two advantages stand out:
no need to convert the whole line into a high-spec oxygen-free workshop
existing filling, encapsulation and formation equipment can largely be reused, with changes focused on impregnation and curing
The retrofitted line also supports flexible switching between liquid lithium cells and all-solid-state cells, reducing idle risk while solid-state demand is still ramping.
What This Means for Overseas Battery Integrators
Overseas buyers usually do not ask only “is it solid-state”. They ask three practical questions:
Can it be supplied steadily with proper documents — UN38.3, MSDS, third-party reports
Does the module need a new structure, BMS communication and thermal design
Should the current project run on NMC liquid cells first, then switch when solid-state cost drops
As a cell and pack supplier, we work backwards from the application. Commuter e-motorcycles can start with an electric motorcycle battery pack. Commercial sites may need a commercial peak shaving battery system. Outdoor or humid environments benefit from a waterproof lithium battery pack. Special voltage, rate or dimensions go through custom battery pack design. Solid-state samples can be evaluated, while mature NMC cells keep the project moving.
Our Export Inspection Logic Follows the Same Principle
Like the quality logic behind this solid-state line, our export batches are built so the customer can use them immediately after unloading:
- every batch gets a battery voltage internal resistance test to remove outliers
- terminal bolts are rechecked for torque to avoid contact resistance after sea transport
- visually defective cells never enter the packing line
- insulated separation and reinforced pallet packing protect the cargo
The customer receives cells that go straight into module assembly — no sorting rejects, no on-site re-testing. That is what “quality” means for an overseas project.
Send Us Your Project Specs
If you are building an e-motorcycle pack, storage cabinet, AGV or forklift battery, or a prototype vehicle, tell us the voltage platform, target range, battery compartment size and charging requirement. We will not just send a quotation. We will tell you whether mature NMC cells fit better now, or whether waiting for solid-state validation makes more sense — then give you the BMS, structure, packing and lead-time plan.
