From laboratory to hundred ton production line, Rucca solid electrolyte grinding equipment's "three-level jump"

From laboratory to hundred ton production line, Rucca solid electrolyte grinding equipment's "three-level jump"

The industrialization of solid-state batteries is going through a race against time.

The goal of installing sulfide solid-state batteries in 2027 is imminent, and both upstream and downstream of the industry chain are accelerating their efforts. However, a cruel reality is in front of us: solid electrolyte materials with excellent performance in the laboratory, once scaled up to pilot scale and then to large-scale production, often suffer from problems such as poor batch consistency, uncontrolled particle size distribution, and a cliff like drop in performance caused by water and oxygen pollution.

From gram level to kilogram level, from kilogram level to ton level, every step is a gap.

Rucca is here to bridge these gaps. Based on the core technology concept of "D+M+C" (dispersion+grinding+formula combination), we have tailored a grinding equipment system for solid electrolyte quality, covering the entire cycle from research and development, pilot testing to mass production - * * laboratory line, small trial line, and hundred ton production line, with a three-level layout and seamless connection * *, making every step of solid electrolyte from the laboratory to the market solid and stable.

Level 1: Laboratory Line - Run the formula through and thoroughly understand the parameters

The development of solid electrolytes often starts with tens of grams of powder.

At this stage, the core demand of the customer is simple: * * to verify the feasibility of the process route with the least amount of materials and the shortest time * *. Whether it is oxides, sulfides, or other routes, several key questions need to be answered: what particle size is appropriate for grinding? How to control the particle size distribution? Will the crystal structure be damaged during grinding?

Rucca laboratory line equipment is designed specifically for this type of "high-frequency trial and error, rapid iteration" research and development scenario.

High flexibility: Supports ultra-fine grinding media above 0.03mm, capable of achieving ultra fine grinding with D50 ≤ 30nm, covering particle size requirements from submicron to nano meter levels

Controllable parameters: Real time monitoring and adjustment of key parameters such as grinding chamber temperature, speed, flow rate, oxygen content, etc., facilitating customers to establish a complete process database

Low usage: The minimum test quantity can be controlled at the level of one hundred grams, suitable for the early stage of research and development when materials are expensive and samples are scarce

Inert protection: Supports full process nitrogen protection, oxygen content<0.5%, ensuring the stability of highly active materials such as sulfides

A solid-state battery R&D engineer told us, "After conducting three batches of sulfide electrolytes on the Rucca test line, the parameters were basically understood and we directly entered the small-scale test." This is the most authentic recognition Rucca has heard in the field of solid-state battery materials.

The laboratory line solves the problem of whether it can be done or not, finding replicable process windows with minimal trial and error costs.

Level 2: Small trial line - Engineering amplification is not simply about adding quantity

The formula has run smoothly, the next step is to scale up from the hundred gram level to the kilogram level or even tens of kilograms level. Many people know that engineering scaling up is not simply about proportional multiplication - if the flow rate changes, the temperature field changes, or the contact efficiency between the grinding medium and the powder changes, even a slight mistake can make the good results in the laboratory impossible to reproduce.

Rucca's small test line is designed to fill this "widening gap".

Engineering level verification: The equipment structure is the same as the mass-produced model, ensuring that the process parameters during the amplification process are consistent
