The revolutionary advantages of solid-state batteries stem from their high energy density and intrinsic safety. The prerequisite for achieving this is a solid-state electrolyte membrane with a thickness ranging from merely a few to dozens of micrometers.

To translate the performance benefits of this core membrane layer into scalable mass production, a mature and stable coating process is key.

MANST Wet-Process Thin-Coating Technology for Solid-State Electrolytes—which involves formulating solid-state electrolyte powder and binders into a slurry, then precisely transferring it onto a substrate via coating equipment to dry and form a film—is currently the industry's mainstream production route. It achieves extreme areal density control, perfectly meeting the core requirements for ultra-thin, highly uniform electrolyte layers in solid-state batteries.

However, to truly transform the theoretical advantages of this process route into replicable, stable, and controllable mass production capabilities, the core lies in a set of high-precision, fully process-controllable coating equipment systems.

Relying on proprietary wet slot-die coating and full-process closed-loop control technologies, MANST Wet-Process Thin-Coating System for Solid-State Electrolytes achieves micrometer-level precision control of dry film thickness from 1 to 60μm. Its non-contact coating process avoids substrate damage and offers excellent adaptability to electrode substrate roughness, significantly reducing fatal defects such as missed coatings and pinholes in ultra-thin layers. Within the overall manufacturing process, a double-sided step-by-step coating method ensures stable formation of the electrolyte layer, addressing common industry pain points such as uneven thin coating, high interfacial impedance, and low yield rates.

Furthermore, the MANST system boasts a maximum coating speed of 60m/min, far exceeding the industry standard of 5-30m/min. Coupled with a mature "front coating → drying → back coating → drying" process, it perfectly matches the capacity requirements of GWh-level production lines. Additionally, the slot-die coating process ensures higher material utilization, significantly reducing slurry waste.

Notably, the system features strong material compatibility, capable of handling slurries for mainstream solid-state electrolyte systems including sulfides, oxides, and polymers. This aligns perfectly with the evolution of industry technology routes, helping battery manufacturers avoid the risks of production line retrofitting due to technological iterations.

In addition, the fully enclosed feeding and coating system achieves full-link water and oxygen isolation and cleanliness control—from slurry storage and precision delivery to slot-die extrusion. This effectively prevents impurity contamination, reduces the risk of hydrolysis and denaturation in sensitive slurries, and significantly improves slurry stability and coating yield.

Targeting the core process pain points of solid-state battery mass production, MANST Wet-Process Thin-Coating System for Solid-State Electrolytes provides a mature, mainstream solution for the industrial preparation of solid-state electrolyte layers, playing a key and positive role in driving the commercialization of solid-state batteries.
