Industrialisierung der neuen Generation von Lithium-Ionen-Lithium-Ionen-Batterieausrüstung

Recently, the "New Energy Vehicles" Key Special Management Office of the High Technology Research and Development Center of the Ministry of Science and Technology (hereinafter referred to as the "Special Office") organized an expert group to conduct a mid-term inspection on the "Industrialized Technology Development of the New Generation Lithium Ion Power Cell" project led by Ningde Times New Energy Technology Co., Ltd. in Ningde, Fujian Province. More than 40 people attended the meeting, including leaders of Fujian Provincial Science and Technology Department, project leaders and representatives of participating units, project leaders and key members, project responsible experts, mid-term inspection expert team and relevant personnel of the special office.

This mid-term inspection adopts a combination of meeting review and on-site verification to review the project. The project leader made a detailed report on "project objectives and scheme design, progress, key technology innovation and achievements, project organization, implementation and management, and plans for the next stage". The expert group positively affirmed the project progress and on-site inspection results, and further refined the project innovation points Clear opinions and constructive suggestions were put forward on the industrialization and application of the achievements of high specific energy and high safety lithium ion power battery.(Lithium - Ion Battery Equipment)

With the goal of developing a new generation of lithium-ion power battery, the project uses high nickel positive electrode and silicon carbon negative electrode to develop lithium-ion battery samples with specific energy ≥ 304Wh/kg. The sample capacity is 65.9Ah, and the capacity retention rate is 97% after 580 cycles of 1C/1C at room temperature. The application integration and verification of safety technology in battery cells have been carried out, and safety tests such as short circuit, hot box, extrusion and overcharge have been passed; The research on battery failure mode and mechanism model and life prediction technology has been carried out. The evaluation time of product reliability has been shortened by 60%, and the verification cost has been reduced by 50%. New methods and technical support have been provided for the design verification of batteries. The project is progressing smoothly, and the mid-term goal is expected to be achieved.
