Starting from a 20-square-meter laboratory in 2013, and now having two major industrial bases and obtaining the national key small and medium-sized enterprise qualification, Wu Xiongwei and Yin Feng New Energy have, over a decade, blazed a unique path in the field of hard technology through the efforts in Yuelu High-tech Zone. 

Wu Xiongwei, a doctoral graduate from Central South University. During his studies, the research group offered topics such as lithium batteries, sodium batteries, and vanadium batteries. Many of his classmates who worked on lithium batteries went to companies like Ningde Times and BYD. However, he chose the relatively less popular all-vanadium liquid flow battery at that time and went to Japan for further studies. His reasoning was clear: Lithium-ion batteries and sodium batteries are mainly used for high-power, short-term energy storage, while all-vanadium liquid flow batteries are for high-power, long-term energy storage and have a high safety factor. As the scale of energy storage increases, the market's demand for safety becomes increasingly important. "There is a saying that 'the times call for heroes', and safe energy storage requires new technologies like all-vanadium liquid flow batteries," Wu Xiongwei said. 

After the enterprise settled in Yuelu High-tech Zone, the park provided crucial support during the process of technological research and industrialization. Wu Xiongwei explained: "We have conducted experiments for over a decade and proposed a new pure chemical preparation method. For the first time globally, we successfully achieved the green preparation of electrolyte using pure chemical methods. During the process of technological upgrading, the park provided valuable intellectual support and talent guarantee." Yuelu High-tech Zone is close to Central South University and Hunan University, and it is the talent center of Changsha. "Our company has a very high reserve of high-tech talents, and we are one of the companies with the most concentrated talents in the industry." 

With the support of the park, the core product of Yinfeng New Energy - the blade-type battery stack - has undergone three generations of iterations, with its performance doubling while the price has dropped by 40%. Wu Xiongwei said, "BYD has the blade battery. Based on the square battery, after three to five years of efforts, we developed a new generation of blade-type battery stack. The park provided significant policy and talent support." 

When it comes to the most indispensable functions of Yuelu High-tech Zone for enterprises engaged in the long-term development of cutting-edge technologies, Wu Xiongwei mentioned that the first is the strong support from the leadership. Within just three or four years of the company's establishment, it has obtained the qualification of a national key small and medium-sized enterprise and the title of provincial and ministerial-level platform. The second is that the park has provided a high-level talent program in response to the company's needs for rapid development. The third is the support for intellectual property protection, with the new structure of the blade stack of Yinfen New Energy having applied for both national and international patents. 

Based on the unique inherent safety advantages of all-vanadium liquid flow batteries, and leveraging the complete scientific and technological innovation and talent system of Yuelu High-tech Zone, Yinfeng New Energy is accelerating the promotion of the safest batteries to the market.
