At the 25th China International High-Tech Achievements Fair, a newly developed lithium-ion battery is undergoing the ultimate test of extreme temperatures, ranging from a scorching 80°C to a freezing -70°C.
Capable of withstanding heat, enduring ice and snow, charging rapidly, and featuring low costs, this super-powerful lithium battery was researched and developed over a span of 10 years by the Advanced Energy Storage Technology Center at the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences. It is China's first battery core product with a wide temperature range, low cost, and long lifespan, and it is expected to reshape the future landscape of the new energy industry upon its release.
Due to limitations in battery materials, traditional lithium-ion batteries operate within a temperature range of 0°C to 40°C, with a significant decline in discharge performance below 0°C. To address this, the research team dedicated nearly a decade to developing a new type of lithium-ion battery technology that is both freeze-resistant and heat-resistant, simultaneously ensuring performance in low and high temperatures. The core members of the research team explained that by innovating the battery's negative electrode materials and electrolyte system, they directly expanded the battery's operational temperature range, with the lowest working temperature reaching -70°C and the highest working temperature reaching 80°C, achieving a broad temperature application range for severe cold and hot conditions.
After years of technical breakthroughs, the new wide-temperature-range battery technology has matured and entered the market promotion stage. The team has established extensive and in-depth collaborations with leading companies in electric bicycles, new energy vehicles, and the energy sector. Batch battery performance evaluations have met usage requirements. Test results indicate that using aluminum-based II manganese lithium core products developed for low-speed electric vehicles, the discharge capacity retention rate still exceeds 60% at -50°C. Similarly, lithium iron phosphate core products developed for new energy vehicles can efficiently charge at -30°C, with a charging capacity exceeding 91% of the initial capacity.
According to team members, this new lithium-ion battery technology has achieved large-scale production of battery core products for various applications, including energy storage and power. In June of this year, it was applied and demonstrated in distributed energy storage projects in northeastern China and other regions.
