Zhongxinhang: The industry's first OS high-manganese iron lithium battery, supporting the cruising range of the vehicle up to 700 kilometers

IT House August 29 news, according to the official news of China Innovation Aviation, on August 28, Xie Qiu, Vice President of China Innovation Aviation, delivered a speech on "OS High Manganese Iron Lithium Battery" at the 2022 World New Energy Vehicle Conference (WNEVC). Keynote speech and announced the industry's first OS high manganese iron lithium battery. Xie Qiu said that the battery platform technology of the OS was released at the World New Energy Vehicle Conference in Hainan last year. After more than a year of hard work, the pilot test has been completed, and the reliability test of the relevant supporting models is currently being carried out. The OS battery uses the first performance principle to reconstruct the structure and process manufacturing technology of the battery cell. It is the fourth packaging form after the cylinder, soft pack, and square. It has higher energy density and higher manufacturing efficiency. , and higher space utilization. The first-generation lithium iron phosphate battery pack using OS technology has an energy density of 152Wh/kg, which should be the highest value in the industry so far. At the same time, the overall energy density retention rate has reached 77%, supporting a vehicle cruising range of more than 600 kilometers. . The prerequisite for all this is that the height of the battery pack is only about 110 mm. If the height of the battery pack is set to a height of 135 mm, which is more common in the industry, the cruising range of the whole vehicle can exceed 700 kilometers. Xie Qiu said, "Based on the understanding of battery user experience, combined with related material technology and structural technology, we have developed a high-manganese iron lithium battery for OS. It has the following characteristics: first, better safety, we used TPP2 .0, the industry's first thermoelectric separation technology, which ensures the robustness of system safety. Second, it greatly reduces the amount of precious metals, including nickel, cobalt and lithium, helping users to achieve the same mileage. Under the condition of lower purchase cost. Third, the height of the battery pack is reduced by 7%, the ground clearance is higher, and the probability of bumping is reduced. Fourth, the energy density of the phosphate battery pack reaches 180Wh/kg, and the energy density The retention rate has exceeded 80%; fifth, support the vehicle to reach 700 kilometers. Sixth, it can be repaired and dismantled. Seventh, in terms of energy replenishment experience, we can refill and replace it.” IT Home learned that, According to the July 2022 power battery monthly data released by the China Automotive Power Battery Industry Innovation Alliance, in July, my country's power battery installed capacity was 24.2GWh, a year-on-year increase of 114.2% and a month-on-month decrease of 10.5%. Among them, CATL ranked first with 47.19%, Fudi Battery (BYD), China Chuanghang, Guoxuan Hi-Tech and Xinwangda accounted for 25.23%, 6.07%, 4.70% and 3.11% respectively. Rank 2-5.
