Bluego New Energy’s Li Lifei: Strategic Development of Comprehensive Electrolyte Technology to Meet Market Demands and Future Directions

Exclusive Interview with Li Lifei of Langgu New Energy: Positioning a Comprehensive Technology Route for Electrolytes to Meet Market Demand and Future Directions

Published on: October 20, 2025

The International Summit on Power Battery Applications (CBIS) has emerged as a significant global event in the new energy battery industry since its inception in 2016, successfully hosting nine consecutive sessions. This year marks the tenth summit, CBIS2025.

Over the past decade, the CBIS summit has witnessed and contributed to the rapid growth of the new energy battery industry in collaboration with global stakeholders.

In celebration of the tenth anniversary of the CBIS summit, Battery China has meticulously organized a high-end dialogue series titled “Ten Years of Dialogue at CBIS”. This initiative invites senior executives from battery, materials, and equipment industries, along with representatives from industry organizations, to reflect on the industry’s evolution, analyze trends, and explore development strategies.

As the energy density ceiling of traditional liquid batteries approaches, a revolutionary material—solid-state electrolytes—is emerging as a beacon for the new energy sector.

The CBIS summit, co-hosted by the China Chemical and Physical Power Sources Association and Battery China, is a well-known brand event within the industry. This year, the Power Battery Applications Division is seizing the opportunity to launch the “Ten Years of Dialogue at CBIS” series.

Recently, Battery China engaged in an in-depth conversation with Li Lifei from Langgu New Energy to uncover the company’s development trajectory and insights within the solid-state electrolyte sector.

1. Comprehensive Technology Route: Building a “Moat” for the Electrolyte Industry

In the realm of new energy materials, the choice of technology route is critical for the survival and growth of enterprises.

Since its establishment in 2021, Langgu New Energy has implemented a clear corporate strategy: to develop a comprehensive technology route encompassing liquid electrolytes, hybrid solid-liquid electrolytes, and solid-state electrolytes, thereby creating an electrolyte system that spans the entire solid-state battery industry chain.

Li Lifei emphasized that this approach is not merely about stacking technologies; rather, it is about precise adaptation to different development stages and application scenarios. Through self-sufficient key raw materials, Langgu New Energy has established a closed loop from basic materials to end industries, aiming to become an industry leader with a focus on liquid electrolytes, hybrid solid-liquid electrolytes, and solid-state electrolytes.

Currently, this strategy is firmly in place. “Customers are not looking for a single product but a comprehensive solution that aligns with their technology route,” stated Li Lifei. Langgu New Energy now boasts the capability to supply a full range of products including solid-state electrolytes, in-situ solidification electrolytes, and new electrolyte solutions for lithium and sodium batteries, addressing both current demands and future directions of the new energy battery market.

In Battery China’s perspective, this comprehensive technology route allows Langgu New Energy to meet the mass production needs of current customers while positioning itself for the next generation of battery technology, thereby creating a unique competitive advantage.

2. Undertaking National Projects to Propel Solid-State Battery Breakthroughs

As one of the main focal points for the “next-generation technology” in the new energy industry, solid-state batteries have become a key area of global competition.

Langgu New Energy, leveraging its technical expertise, has participated in several national key research projects on solid-state electrolytes, including oxides and sulfides, becoming one of the few companies simultaneously advancing both major solid-state electrolyte technology routes.

According to Battery China, participation in national projects is not only an honor for the company but also a recognition of its technological strength by regulatory authorities. Li Lifei revealed that Langgu New Energy has achieved significant breakthroughs in solid-state electrolyte technology, laying a solid foundation for future industrialization.

In this context, Langgu New Energy’s technical prowess is being transformed into market competitiveness. Backed by advanced solid-state electrolyte technology and industry-leading scalable production capacity, the company has established collaborations with hundreds of downstream clients, successfully integrating its products into major battery and materials enterprises, thus facilitating breakthroughs in solid-state battery technology.

“The validation process from major clients is extremely rigorous, with each step—from performance testing to mass production adaptation—testing the stability of our technology,” Li Lifei admitted. It is through continuous technological iteration and stable supply capabilities that Langgu New Energy has secured its position in a highly competitive market.

3. Multi-Scenario Applications and Capacity Expansion to Seize Market Opportunities

In terms of capacity planning, Langgu New Energy has established two production bases in Liangyin, Jiangsu and Zibo, Shandong, forming a north-south production capacity framework that ensures large-scale supply of its products.

“Capacity is the vehicle for technology implementation; without scalable production, even the best technology remains confined to the lab,” Li Lifei noted. “This multi-base model not only meets current order demands but will also safeguard future technological upgrades.”

Data shows that in 2022, Langgu New Energy’s Liangyin base constructed the industry’s first production line for ton-level oxide solid-state electrolytes, successfully completing technology validation. By 2024, its Zibo base will launch production lines for 50,000 tons of in-situ solidification electrolytes and new electrolyte solutions for lithium and sodium batteries, with a 100-ton full solid-state electrolyte production line expected to be operational by 2025, achieving commercialization across the entire technology route.

Li Lifei indicated that due to the explosive demand for semi-solid and full solid-state batteries, Langgu New Energy plans to increase oxide electrolyte production capacity to the ton level and expand sulfide production lines from ton to ten-thousand-level, with site selection for related projects already underway.

Regarding the future of the industry, Li Lifei holds a clear perspective. He believes that semi-solid batteries will initiate mass production processes ahead of others. “In the next 3-5 years, semi-solid batteries will gradually release capacity and capture a certain market share. By around 2030, they are expected to replace most applications of liquid batteries across sectors such as 3C, energy storage, and new energy vehicles.”

In response to this trend, Langgu New Energy has introduced two semi-solid electrolyte solutions: a collaborative solution between electrolyte and oxide solid-state electrolytes, and a comprehensive solution integrating in-situ solidification electrolytes with oxide solid-state electrolytes. Both solutions have entered the small-batch application phase within the industry.

Li Lifei noted that the industrialization of full solid-state batteries will require a longer accumulation period. He sees 2027 and 2030 as critical milestones for the industry. “By 2027, we expect to achieve demonstrative applications, and by 2030, we anticipate commencing civilian commercialization.”

He pointed out that due to their high safety and energy density characteristics, full solid-state batteries will focus on high-end sectors in the future, including high-end new energy vehicles, low-altitude equipment, defense, robotics, and medical applications.

Over the past decade, the CBIS summit has continuously facilitated the commercialization of new technologies for battery and materials companies by creating platforms for technical exchanges, connecting upstream and downstream of the industry chain, and establishing relevant standards. Li Lifei is highly optimistic about CBIS 2025, particularly in terms of advancements in power battery and application technologies, and he looks forward to establishing broader connections with clients and partners.

Li Lifei expressed that Langgu New Energy will continue to align with the association’s efforts to contribute significantly to the industry. Additionally, he hopes to collaborate with industry chain enterprises to expand globally, further enhancing the competitive advantage of China’s battery industry in the global new energy market, making this “Chinese business card” even more brilliant.
