Sichuan Changhong Battery Co., Ltd. has introduced the full set of sintered electrode production line and technology imported from VARTA Germany. The positive and negative electrodes sintered by VARTA technology have the characteristics of high mechanical strength, good consistency, good performance of fast charge, small floating current, high cleanliness, and so on. Changhong sintered electrodes are the core parts of dedicated sintered type nickel cadmium batteries for aviation, ship and locomotives, as well as the core parts of super capacitor for electric cars.
