Vivo pioneered graphite lamination reconstruction technology, which brought greater energy density through the reconstruction of negative graphite. Compared with the traditional pole piece cold pressing technology, the super pole piece cold pressing technology can compact the pole piece to a greater extent, reduce the rebound thickness of the pole piece and effectively improve the energy density. Micron-scale laser array etching technology establishes new ion channels through negative electrode surface treatment, which improves the transmission, storage and transmission efficiency of electrolyte and improves the charging performance.
