1. Stricter Battery Safety Standards: No Fire, No Explosion Under Specified Test Conditions
On July 1, 2026, China's mandatory national standard GB 38031-2025, Safety Requirements for Power Batteries Used in Electric Vehicles, officially came into effect.
The updated standard introduces more stringent battery safety requirements, including enhanced thermal propagation testing and requirements to prevent fire and explosion under specified test conditions.
Battery safety is no longer simply a competitive advantage. It has become a fundamental requirement for market access and commercial deployment.
As the battery industry increasingly prioritizes safety alongside driving range and energy density, all-solid-state batteries are gaining attention as a promising next-generation technology.
Q: Why Are Solid-State Batteries Considered Safer Than Conventional Lithium-Ion Batteries?
A: Conventional lithium-ion batteries typically use flammable organic liquid electrolytes, which can contribute to fire and thermal runaway risks under abusive conditions.
Solid-state batteries replace conventional liquid electrolytes with solid electrolyte materials. Certain inorganic solid electrolytes, particularly oxide-based materials, offer favorable thermal stability and reduced flammability compared with conventional organic liquid electrolytes.
However, the safety characteristics of solid electrolytes vary by chemistry. Sulfide electrolytes, for example, require careful moisture management because exposure to water can cause degradation and the release of hazardous gases.
Therefore, improved electrolyte safety does not automatically guarantee complete battery safety. Electrode compatibility, interface stability, battery architecture, and manufacturing quality remain critical.
For solid-state batteries to progress toward automotive commercialization, manufacturers must overcome another major challenge: industrial-scale engineering and production.
2. The Core Challenge: Bridging the Gap Between Laboratory Research and Industrial Manufacturing
Scaling up solid-state battery materials is not simply a matter of increasing production volume. It requires a transition from gram-scale laboratory feasibility to ton-scale manufacturing with consistent product quality.
For both oxide and sulfide solid electrolytes, a major industrialization challenge lies in achieving stable, continuous powder processing under carefully controlled manufacturing conditions.
Sulfide Solid Electrolyte Production Lines
Sulfide solid electrolytes are attracting significant attention because of their high lithium-ion conductivity and potential for favorable solid-solid interfacial contact.
However, many sulfide compositions are highly sensitive to moisture.
Industrial production therefore requires coordinated control of enclosed material conveying, inert atmosphere protection, corrosion resistance, moisture management, exhaust gas treatment, and process safety.
Uncontrolled exposure to moisture or atmosphere can cause material degradation, potentially compromising product quality and manufacturing yield.
Oxide Solid Electrolyte Production Lines
Oxide solid electrolytes offer favorable chemical and thermal stability, making them an important material platform for solid-state battery development.
Their industrial-scale manufacturing challenges include nanoscale grinding and dispersion, crystalline phase control during sintering, contamination management, and batch-to-batch consistency.
At the thousand-ton production scale, success depends not only on individual equipment performance but also on coordinated process control throughout the entire production line.
Material innovation alone is not enough. Equipment engineering, process integration, and reliable project delivery are essential to translating laboratory results into industrial manufacturing capability.
3. BOYEE's Approach: Turnkey EPC Solutions for Both Oxide and Sulfide Solid Electrolytes
For manufacturers developing solid electrolyte materials, purchasing individual machines is only one part of the process.
What they need is an integrated production system in which material handling, process equipment, environmental control, automation, and safety systems operate together.
BOYEE Industrial provides turnkey EPC solutions for oxide and sulfide solid electrolyte production lines, integrating process engineering, equipment manufacturing, system integration, installation, and commissioning.
Oxide Solid Electrolytes: Thousand-Ton-Scale Production Line Experience
BOYEE provides integrated equipment solutions covering key processing stages, including raw material feeding, mixing, nano-grinding, sintering, powder finishing, and packaging.
The company has successfully delivered a thousand-ton-scale oxide solid electrolyte production line in Hubei, China, and has also signed another thousand-ton-scale oxide solid electrolyte EPC project in Huizhou.
These projects demonstrate BOYEE's engineering experience in scaling up oxide solid electrolyte manufacturing and integrating multiple processing stages into industrial production systems.
Sulfide Solid Electrolytes: Hundred-Kilogram-Scale EPC Project Delivery
Sulfide electrolyte processing places particularly demanding requirements on equipment sealing, environmental isolation, material compatibility, and operational safety.
To address these challenges, BOYEE has developed customized equipment configurations, including glovebox-integrated bead milling systems with enhanced sealing and corrosion-resistant alloy components.
More recently, BOYEE successfully supported a leading Chinese new energy vehicle manufacturer in implementing a hundred-kilogram-scale sulfide solid electrolyte turnkey EPC production line.
The project provides an engineering platform for controlled sulfide electrolyte processing under stringent environmental conditions and supports further process validation and scale-up development.
Q: What Is the Difference Between a Turnkey EPC Production Line and Purchasing Equipment from Multiple Suppliers?
A: Solid electrolyte manufacturing involves multiple interconnected processes, each with its own technical requirements.
When equipment is sourced independently from different suppliers, manufacturers may face challenges related to interface compatibility, system integration, commissioning coordination, and project accountability.
BOYEE's turnkey Engineering, Procurement, and Construction (EPC) approach brings process engineering, equipment manufacturing, system integration, installation, and commissioning under a coordinated project delivery framework.
This helps customers simplify supplier coordination, improve process compatibility, and reduce integration-related risks during production line development.
From Material Innovation to Industrial Manufacturing
The safety potential of solid-state batteries begins with material science, but translating that potential into reliable commercial products requires robust engineering and manufacturing systems.
From thousand-ton-scale oxide solid electrolyte production lines to hundred-kilogram-scale sulfide electrolyte EPC project delivery, BOYEE Industrial continues to advance its engineering capabilities across both major solid electrolyte technology pathways.
By combining core equipment manufacturing, process engineering, and turnkey EPC delivery, BOYEE helps bridge the gap between solid electrolyte research and scalable industrial production.
