The new standard defines three types of batteries based on ion transfer methods: liquid electrolyte, hybrid solid-liquid, and pure solid-state. This classification system aims to clarify the technology’s progression from lab research to commercial applications.

Under this draft, genuine solid-state batteries must meet a stringent weight loss rate requirement of 0.5% under vacuum drying conditions. This is stricter than the previously proposed threshold of 1%, indicating China’s commitment to high standards for these emerging technologies.

The document also includes classifications by electrolyte type (sulfide, oxide, polymer, halide, or composite) and conducting ion type (lithium-ion, sodium-ion). These details will be crucial as the industry moves toward commercialization of solid-state batteries.

Separate technical specifications for solid-state electrolytes are also being drafted alongside this standard. This comprehensive approach signals China’s intent to lead in the development and regulation of next-generation battery technologies.

This standard marks an important milestone in China’s efforts to dominate the global market for electric vehicle technologies. It sets the stage for further regulations on performance and safety.

Tinci’s recent acquisition of eight patents highlights its strategic focus on solid-state battery technology. The company aims to enhance the safety and longevity of batteries through these innovations. With four electrolyte formulations and their preparation methods covered in the new patents, Tinci is well-positioned to influence future advancements in high-energy density batteries.

Tinci’s existing relationship with CATL, a leading Chinese cell manufacturer, has been strengthened by recent material supply agreements. In June 2024, Ningde Kaixin, a subsidiary of Tinci, signed an agreement worth over 10 billion yuan for the supply of electrolyte products equivalent to 58,600 tonnes of solid lithium hexafluorophosphate. This contract supports approximately 410-470 GWh of CATL battery output and underlines Tinci’s importance in the supply chain.

The pilot line construction underway at Tinci will enable the production of kilogram-level samples for testing by downstream cell manufacturers, with a focus on high energy density and extended cycle life. This development is critical as it bridges the gap between laboratory research and real-world applications, paving the way for future commercialization of solid-state battery technology.

While Tinci’s patents do not immediately impact business operations, they are expected to bolster intellectual property protection and support ongoing R&D efforts in next-generation electrolytes. The company’s liquid-phase reaction method extends from its existing lithium salt production technologies, demonstrating a seamless integration of new innovations with current capabilities.

Tinci’s strategic move to secure patents in solid-state battery technology aligns with the broader trend towards innovation in the automotive industry, particularly in China. As competition intensifies among suppliers and manufacturers, Tinci’s advancements are likely to strengthen its competitive edge within the global battery supply chain.

Space charge effects introduce additional resistance during charging and discharging of solid-state batteries. The MPI-P team used advanced microscopic techniques to determine the extent of these zones, which account for about seven percent of a battery’s total internal resistance. This layer is dynamic, changing its behavior based on the state of charge.

The research highlights that while space charges are most significant at the positive electrode, their impact varies with electrolyte materials. Understanding this variability could enable more precise engineering of solid-state batteries to optimize performance and efficiency.

Comparative studies show that lithium-ion batteries often face similar issues but in a different context, primarily due to liquid electrolytes which can lead to dendrite formation. Solid-state batteries aim to mitigate these risks by using solid electrolytes, yet the new findings indicate there are still challenges related to internal resistance and efficiency.

Despite the progress made by MPI-P and their Japanese partners, other research institutions around the world continue to explore similar issues. For instance, studies at Stanford University focus on improving ion conductivity in solid-state batteries through material innovation.

This study marks an important step towards optimizing the efficiency and power density of solid-state batteries. Further research will be necessary to translate these insights into practical applications that enhance battery technology for automotive and other industries.

GAC has been dedicated to researching solid-state battery technology since 2016, focusing initially on polymer-based systems before branching out into sulfide-based cell development. The company plans to ramp up production gradually over the next decade, aiming for mass manufacturing between 2027 and 2030.

With an eye on increasing energy density, GAC is employing advanced materials like ‘sponge silicon’ in their battery anodes, which are manufactured using a dry process. This innovative approach could potentially increase the range of electric vehicles up to 1,000 kilometers under Chinese test conditions, significantly enhancing vehicle performance.

As other major players like SAIC and Chery also push forward with solid-state batteries, GAC is positioning itself as a leader in this emerging technology. The company’s Hyper brand, introduced just two years ago, will be among the first to integrate these cutting-edge batteries into production vehicles starting from 2026.

While mass adoption of solid-state batteries remains several years away, early adopters like GAC are laying the groundwork for a future where these advanced cells become standard in electric vehicles. As we reported earlier this year, numerous automakers and battery manufacturers across China are working diligently to bring these technologies to market.Read more about their progress.
