14, Guangzhou Penghui Energy Technology Co., Ltd. and Qingdao North Bank Holding Group signed a cooperation agreement on the demonstration project of 5MW/10 MWh sodium-ion energy storage power station, which is located in the large data center of Qingdao North Bank Holding Co., Ltd. and realized the large-scale application of sodium-ion core in the northern energy storage power station for the first time. It marks that Penghui Energy Sodium Ion Core has been formally introduced into the market and entered the stage of large-scale commercial application, which is of symbolic significance to the industrialization of sodium electricity.
5MW/10 MWh Sodium Ion Energy Storage Power Station Demonstration Project Signing Site
The 5MW/10 MWh sodium ion energy storage power station project is located in the big data center of Qingdao North Bank Holdings, which is the first integrated application of sodium ion batteries in the new energy storage and the new infrastructure of the big data center. This project will effectively improve the energy efficiency level of Qingdao North Bank Big Data Center, enable the construction of green data center, and support Qingdao's high-quality development driven by digitalization.
In the critical period of energy transformation, promoting the research and development of sodium-ion energy storage technology is of great driving significance to China's future energy structure reform. Compared with the regional distribution of lithium, sodium is abundant in China and its cost is lower. Sodium-ion compounds have strong accessibility, sodium-ion batteries have relatively stable electrochemical properties and safety, better safety, wider working temperature range, higher rate performance, and high adaptability to large storage scenarios. Therefore, Penghui Energy believes that power storage will be a long-term market for sodium power.
Three years ago, Penghui Energy laid out the technology in the field of sodium-ion battery research, and now the company has made remarkable achievements in the fields of sodium-ion material system construction, supply chain cooperation, product system research and development. In 2022, it has completed the batch trial production and sample delivery test of small cylinder, large cylinder and square battery core, applied for a number of sodium related invention patents, and published a number of research papers in Top journals.
In the layout of sodium ion products, Penghui Energy adopts the strategy of layered oxide and polyanion system, and achieves a number of technological innovations and breakthroughs. For the layered oxide system, a high-voltage system is developed to increase the energy density to 150 Wh/kg, with a cycle life of more than 3000 weeks; in the polyanion system, a highly stable system is constructed through material innovation, with a cycle life of more than 6000 weeks, which revolutionizes the core pain point of low energy density and cycle life of sodium electricity. In the demonstration project of 5MW/10 MWh sodium-ion energy storage power station of
Qingdao North Bank Holdings Big Data Center, Penghui Energy will provide a complete sodium-ion technology solution to realize the construction and application of sodium-ion battery core in the new power load management system. The project not only effectively reduces the operating cost of the data center, but also actively participates in the regulation of the social power grid to improve the stability and reliability of the social power grid.
