Product Description
Performance Advantages
Driven by global carbon neutrality goals, sodium-ion batteries have emerged as a prominent player in the energy storage sector due to their abundant resources, low cost, and exceptional safety. Sodium, with a crustal abundance of 2.75% (far exceeding lithium’s 0.0065%), is widely distributed globally, effectively mitigating risks associated with overdependence on lithium resources. Key advantages include a cost approximately half that of lithium-ion batteries, a cycle life of up to 3,000 cycles (compared to 300 cycles for lead-acid batteries), and stable operation in extreme temperatures ranging from -40°C to 80°C, making them ideal for energy storage in frigid regions and winter electric vehicle charging. Additionally, sodium-ion batteries utilize aluminum foil for both cathode and anode current collectors, further reducing material costs. Haosheng New Energy’s achievements include collaborative innovation with Southwest University through a joint sodium-ion battery materials laboratory, extensive industry validation via sample testing with leading companies like Vision Technology, Lishen New Energy, and Guoxuan High-Tech, three generations of technological breakthroughs in cathode materials (with the latest polyanionic system achieving advanced performance), and accelerated industrialization with an annual production capacity of 20,000 tons of sodium-ion battery materials across a 183-acre facility.
