Developing and developing next-generation battery technology is an important development strategy for Penghui Energy. Sodium ion batteries have the core characteristics of abundant resources and higher cost, and are one of the important technological forces for the next generation of new energy. Penghui Energy started the research and development of sodium ion battery technology in 2019, continuously tackling core difficulties, and launched the first generation of sodium ion batteries in 2023. Recently, Penghui Energy's research on the new generation of sodium ion batteries has achieved key research results in both polyanion systems and layered oxide systems.
Compared to the first generation of polyanion technology, Penghui Energy's new generation polyanion system products have improved their capacity and voltage platform by developing new positive electrode materials, increasing cell energy density by 21%, and increasing capacity by 20Ah at the same size! At the same time, in terms of cycle life, it can achieve over 10000 cycles at 80% SOH; In terms of cost, compared to the first generation, it has decreased by 30%. The ultimate quality price ratio helps to enhance the competitiveness of large-scale industrialization of sodium ion batteries and further promote market applications.
At present, Penghui Energy's polyanion system sodium ion battery has various models of products such as square aluminum shell 150Ah and 180Ah. The company has successfully implemented the sodium ion battery industrial and commercial energy storage system project and is operating stably. At the same time, it has received multiple potential orders from customers in the energy storage field.
In terms of low temperature, Penghui Energy has overcome the technical difficulties of low-temperature sodium precipitation and effectively reduced concentration polarization in low-temperature environments. It has successfully achieved 100% deep discharge (DOD) charging in the temperature range of -20 ℃~50 ℃, and its cycle stability performance has reached a new level.
In terms of safety, through the integrated innovative design of new thermal runaway inhibitors, positive and negative electrode binders, and in-situ polymeric electrolyte technology, Penghui Energy has significantly improved battery safety without affecting electrochemical performance. It has been tested through needle puncture and thermal runaway testing, without fire or explosion! In terms of energy density, Penghui Energy's layered oxide system sodium ion battery can reach 150Wh/kg, suitable for start stop power supply, light power and other fields, and has received interested orders from well-known customers.
Penghui Energy's sodium ion battery products are covered in various packaging forms such as cylindrical and square aluminum shells, meeting a wider temperature range and ensuring higher safety, providing users with a more efficient, safe, and stable battery experience.
The rise of sodium ion batteries is a new breakthrough in battery technology and opens up new imaginative space for the sustainable development of the battery industry in the future. As a company driven by technological innovation, Penghui Energy will continue to cultivate its battery technology soil for 24 years in the new year, further strengthen technological innovation, and use safe, reliable, and innovative high-quality battery products to help the world move towards a green, low-carbon, and beautiful future!
