Recently, SVOLT announced that its second-generation short-knife fast-charging lithium iron battery cells have been delivered in large quantities at two production bases in Shangrao and Yancheng, and is expected to achieve the delivery target of 100,000 sets within this year. For the first time, this cell adopts the flying stack thermal composite technology, combined with the self-developed third-generation lithium iron phosphate cathode material, to achieve an energy density of up to 188Wh/kg under 2.2C fast charging performance, and the peak value can reach more than 3C, shortening the charging time to 15 minutes.
In the production of the second generation of short knife cells, SVOLT has applied the industry's highest efficiency lamination 3.0 process - flying stacking. This technology solves the long-standing problems of low lamination efficiency and low product yield, and brings significant advantages to the production of short knife cells. The fly-stacking process not only improves the stacking efficiency, but also reduces the internal resistance of the cell, improves the fast charging performance, and ensures the energy density, cycle life and fast charging capacity of the cell.
Material innovation: third-generation lithium iron phosphate cathode materials and high-performance small-particle graphite anodes In terms of material innovation, SVOLT has made iterative innovations in the cathode, anode, electrolyte and separator of the second-generation short-knife cell. In particular, the application of the self-developed third-generation lithium iron phosphate cathode and high-performance small-particle graphite anode, as well as the asymmetrical separator design and the use of new adhesives, have significantly improved the performance of the battery cell.
SVOLT's second-generation short-knife batteries are also produced by the third-generation battery cell production line, which gathers SVOLT's innovative achievements in various fields such as equipment development and intelligent integration. The wide coating technology applied in the production line, the AGV automatic loading and unloading system, and the advanced fly-stacking process all ensure the high quality and manufacturing efficiency of the battery cells.
With the large-scale shipment of short-knife fast-charging cells and the large-scale market demand for high-quality short-knife fast-charging cells, the installed capacity of SVOLT is expected to further increase. According to the latest data, in the first half of this year alone, SVOLT has delivered a total of 53,000 sets of battery packs overseas.
Through continuous technological innovation and material innovation, SVOLT is leading new breakthroughs in fast charging technology. The large-scale delivery of the second-generation short-knife fast-charging lithium iron battery cells marks that the company has made important progress in the field of fast charging technology and injected new vitality into the development of the new energy vehicle industry.
