Driven by the global energy transition and the 'dual carbon’ strategy, the new energy battery industry is experiencing explosive growth; coming with it is rising demand for precision and stability of back-end manufacturing equipment.

Guangzhou Langtian New Energy Technology Co., Ltd. (hereinafter referred to as Langtian New Energy), a 'national high and new-technology enterprise' and a 'provincial specialized, refined, differentiated, and innovative (SRDI) SME' in Huadu District, has independently developed the 'impact-free adaptive intelligent formation and grading technology and equipment,' which has been applied on a large scale. Thanks to breakthroughs in core technologies, it has not only filled multiple gaps in domestic industry of lithium battery back-end manufacturing equipment but also injected new momentum for the high-quality development of the Greater Bay Area's new energy industry cluster.

With eyes fixed on industry bottlenecks

a decade's efforts were put to overcome technical barriers

Founded in 2012, Langtian New Energy is a high-end smart equipment company integrating R&D, production, and sales of new energy lithium batteries, solid-state batteries and sodium-ion batteries.

'The core back-end process is the “last mile” of lithium battery production, which has direct impact on the battery’s consistency, safety, and lifespan.' According to Fei Jialiang, board chair of Langtian New Energy, traditional formation and grading equipment has long been plagued by “inaccurate measurement, slow matching, and uneven control”, which means frequent damped oscillations of charge and discharge current, high surges, slow shutdown speed, and lack of flexibility in mechanical regulation methods, resulting in overstated battery capacity, reduced cycle life, and even safety risks. This directly limits the quality ceiling of high-end battery manufacturing in China.

To break through this bottleneck, Langtian New Energy, with eyes fixed on the new energy lithium battery equipment, has continuously increased investment in R&D and core technology team building, and launched a R&D project to develop “impact-free adaptive intelligent formation and grading technology and equipment.”

'In tackling the technology problem, we worked on both the underlying algorithms and hardware architecture, and managed to control the voltage stability to an ultra-high range of ±0.02% FS. It's like equipping the battery with a “voltage stabilizer,” making the current output as smooth as a calm lake,' said Fei Jialiang.

The successful implementation of this new technology has broken foreign technology monopolies and has become a powerful engine for the company’s leapfrog development. It completely solves the problem of “inaccurate measurement, slow matching, and uneven control” for the industry, and has created during the process a series engineering demonstration achievements suitable for national promotion, including method for uninterrupted current switching between steps of the same type, and method for current curve control of a constant-voltage power supply, which not only greatly improves China's technological autonomy in the global field of lithium battery back-end manufacturing equipment but also builds a solid technical moat for Langtian in a fiercely competitive market.

Technology empowered development

accelerates SRDI company in growth

Technological innovation offers powerful support for promoting sustainable and high-quality development of enterprises. Langtian New Energy has always had its focus on technological R&D and innovation, making it the foundation of the company and accelerating the rapid transformation of technological achievements into market competitiveness.

As a drafting unit of industry standards, Langtian New Energy currently holds more than 40 patents, has been successively recognized as a "National High and New-Technology Enterprise" and a "Guangdong SRDI SME," and was included in Huadu District's "List of Rising Dragons" for high-quality development. The intelligent formation and grading equipment developed by the company is applicable in diverse scenarios, including power batteries, energy storage stations, CCC certified consumer electronics, and research institutes. Having as clients such leading companies as CETC, BYD, Ganfeng Lithium, and Guanyu, the market share of the products of the company remains among the top in South China.

Interaction between government and enterprise

builds an ecosystem for high-quality development

"Our company was established in 2012. The reason we chose with determination to settle in Guangzhou Huadu is precisely because of the District’s forward-looking industrial layout, excellent business environment, and prominent advantages in air-rail intermodal transport." Fei Jialiang frankly acknowledged that in recent years, Huadu District has been vigorously building the GBA "Green Energy Valley” major industrial platform under the mode of "One Hundred Billion in Ten Thousand Mu", which matches perfectly with Langtian New Energy's development vision.

Fei Jialiang also admitted that Langtian's achievements today were inseparable from the precise support from governments and industrial project service centers at all levels. "On one hand, the government precisely pushes and implements tax and fee incentives such as additional deductions for R&D expenses, using "decrease” in taxes to facilitate "increase" of our innovative R&D, which effectively ease financial pressure and enable our continuous investment in core technologies; on the other hand, government and enterprises build school-enterprise cooperation and talent service platforms to effective satisfy the demand for attracting and cultivating high-end technical talent, promoting deep integration of industry and education. It is precisely this high-quality industrial ecosystem that creates fertile ground for Langtian's healthy and sustainable development.”

Focusing on intelligent manufacturing

empowers regional economic leaps

The Guangdong-Hong Kong-Macau Greater Bay Area is currently accelerating the creation of a world-class new energy industry cluster, in which the construction of Huadu's "Green Energy Valley" serves as the core engine. Fei Jialiang stated that in the future, Langtian New Energy would continue to uphold the corporate spirit of "persistence driven by passion, development through innovation," and make sustained efforts across multiple dimensions to empower industries and regional economies.

Focusing on iteration of core technologies:

More investment will be made in R&D, particularly in cutting-edge fields such as new energy lithium batteries, solid-state batteries, and sodium-ion batteries, pushing continuously R&D of impact-free adaptive control, energy-saving digital power supplies, and other foundational technologies, to maintaining a technological lead in the global lithium battery back-end equipment sector.”

Driving upgrade of intelligent manufacturing:

Efforts will be made to achieve transition from a single equipment provider to a "comprehensive lithium battery backend solution" service provider. Deepened industry-university-research cooperation with universities and research institutes will promote the digitization and intelligentization of battery testing equipment, helping the transition of the entire industry from "experience-driven" to "data-driven."

Deep integration into regional development:

And the company will seize the historic opportunity of the Greater Bay Area's "Green Energy Valley" construction, and play the role of "leading goose" as a SRDI enterprise.

"We will continue to drive coordinated development across the industrial chain to form a healthy and sustainable industrial ecosystem, so as to contribute more “Langtian Power” to the high-quality development of the new energy industry in Huadu District and even the GBA.” From solving industry bottlenecks to leading technological transformation, and from deepening niche fields to empowering industrial clusters, Langtian New Energy's growth trajectory is a vivid reflection of the innovation-driven high-quality development of SRDI companies in the Greater Bay Area. With the rise of more "hidden champions" like Langtian, GBA’s vision of "Green Energy Valley" is rapidly becoming a reality.
