SIEHE Showcased Its Industrialization Solution for Sulfide Solid‑State Electrolyte at the 2026 China Solid‑State Battery Symposium

Recently, the 8th China Solid-State Battery Technology Innovation and Industrialization Symposium (2026) was successfully held in Changsha, Hunan. Experts, researchers and enterprise representatives nationwide gathered to discuss technology breakthroughs and industrialization pathways for solid-state batteries. Invited to the event, SIEHE Group highlighted its New-generation Horizontal Plow Vacuum Drying Mixer for sulfide solid-state electrolyte preparation, providing a key solution for sulfide solid-state electrolyte industrialization.

During the event, SIEHE Group GM Liao Li delivered a keynote speech featuring a 3D video, highlighting the Horizontal Plow Vacuum Drying Mixer’s core technical strengths in sulfide solid‑state electrolyte preparation and its precise process control that provides reliable support for industrial‑scale production.

High Vacuum: Overall vacuum level reaches 5 mbar, significantly improving drying efficiency and effect, achieving residual moisture down to 100 ppm while lowering energy consumption.

High Sealing: Equipped with SIEHE's in-house high-performance mechanical seals, designed for high temperature, high pressure, high speed, and high vacuum; includes flushing and monitoring systems for long-term stable operation.

High-Temperature Design: Maximum operating temperature up to 300 °C; features a unique mechanical thermal expansion compensation technology to handle thermal expansion and contraction in high-temperature conditions.

Corrosion Resistance & High Purity: Supports multiple corrosion-resistant metals and surface treatments, including SS304/SS316L stainless steel, wear-resistant steel, duplex steel, nano-ceramic coating, Teflon coating, and silicon carbide coating; prevents equipment-originated contamination and metal impurity ingress, ensuring material purity and electrochemical performance to meet stringent solid-state battery production standards.

The post-symposium exchange was lively, and the SIEHE booth drew many attendees to stop and inquire. Representatives from multiple leading solid-state battery companies, battery material manufacturers, and research institutions engaged in in-depth discussions with SIEHE’s technical team on the Horizontal Plow Vacuum Drying Mixer’s process compatibility, production efficiency, and special material application solutions for sulfide solid-state electrolyte production.

This presentation demonstrated SIEHE Group’s technical expertise and innovation in sulfide solid-state electrolyte material preparation. In the future, SIEHE will continue focusing on critical preparation processes for solid-state battery materials, working with more industry partners to advance solid-state battery technology and industrialization.
