"Three Major Extreme Energy Cell Technologies" Created by Zhongli New Energy
It has always been widely believed in the industry that high energy density and ultrafast charging are difficult to balance at the same time. Based on the LISA3-2-1 R&D strategy, Zhengli New Energy has created an industry-leading Zhengli Extreme Energy technology battery cell system, and has launched a 46 size large cylindrical battery cell that can achieve 4C fast charging at a maximum of 300Wh/kg; Based on this large cylindrical battery cell, the highest 170kWh "Zhengli Qilong" battery system in the new energy passenger vehicle industry has been released.
The rapid development of the new energy vehicle market has put forward higher requirements for battery safety, energy, lifespan, and charging speed. Large cylindrical batteries are increasingly favored in the mid to high end passenger car market due to their relatively small individual energy, high safety, good compatibility with extreme chemical systems, low manufacturing costs, and ease of standardization.
In order to maximize the performance and safety of battery cells, reduce costs, Zhengli New Energy relies on the polar energy technology battery system, and has independently created three core technologies in the industry: polar energy ring, polar energy cover, and polar energy state. It has launched the largest 46 cylindrical battery cells in the industry, with a single capacity of 49.5 Ah, meeting the requirements of ultra safety, ultra-high energy density, ultra long lifespan, and fast charging performance.
Extreme Energy Ring: The traditional 4680 cylindrical battery cell adopts opposite side design for the positive and negative poles, resulting in a long electron transmission path and high internal resistance. Zhengli Xinneng has independently created the same side outlet ear technology, which can significantly shorten the electronic transmission path and reduce the Ohmic resistance. Compared to full pole ear technology, the same side outlet ear design can shorten the electronic path of large cylindrical cells by 80%, reduce Ohmic impedance by 30%, and increase volume utilization by 3%.
Extreme cover: Zhengli Xinneng has upgraded the traditional fluororubber sealing ring design to etching nano injection molding technology, which can reduce costs by 10% compared to traditional top cover integration technology; PPS forms a nanoscale anchor bolt structure and chemical bonding with the top cover and pole surface, and the helium gas tightness is 100 times higher than that of traditional sealing rings.

Polar state: refers to the technology of dual semi-solid battery cells. Zhengli Xinneng has developed solid-state electrolyte surface modification technology and solid-state electrolyte composite separator technology for ultra-high nickel cathode materials. Thanks to this, the initial failure temperature of the large cylindrical battery cell increased by 10 ° C, and the maximum failure temperature decreased by 150 ° C. In terms of power performance improvement, the low-temperature power at minus 20 ° C has increased by 20%.
In terms of patents, as of now, Zhengli Extreme Energy Cell Technology has 291 patent layouts, including 25 nano injection molding, 64 high nickel+silicon carbon, 16 semi-solid state technologies, 125 cylindrical cell technologies, and 61 cylindrical battery pack technologies.
