1、To prevent the active substance from falling off: Tubular plate is in the positive plate on the conductive skeleton set with woven fibre tube, the tube into the active substance. This structure can effectively bind the active substance in the tube, even in the battery charging and discharging process, the plate is subjected to the stress of chemical reaction, the active substance is not easy to fall off, thus greatly improving the stability and service life of the plate.

2、Good corrosion resistance: Tubular plate positive plate skeleton is usually formed by multi-alloy die-casting, the alloy organisation of the grain is small and dense. This special alloy material has good corrosion resistance, which can resist the erosion of sulfuric acid and other substances in the electrolyte, reduce the corrosion loss of the plate, and extend the overall life of the battery.

3、Long cycle life: Due to the tubular plate can effectively prevent the active substance off and has good corrosion resistance, so that the battery in a number of charging and discharging cycle process, the plate can maintain good performance, reduce the plate damage caused by the battery capacity decline and other issues, so the battery cycle life can be extended.

4、Improve high-current discharge capacity: Although the high-current discharge performance of tubular plates is generally slightly worse than that of ordinary plates, the overall high-current discharge capacity can still meet the needs of many application scenarios when the negative plate is properly matched. For example, in some lead-acid battery applications, the negative electrode plate adopts a paste-coated electrode plate and is designed as a radial structure, which can improve the utilisation rate of active substances and high-current discharge capacity, and in conjunction with the tube-type positive electrode plate, the battery can also have a better performance when discharging at high currents.

5、Improve active substance utilisation: The active substance inside the fibre tube has a relatively large contact area with the electrolyte, so that the active substance can participate more fully in the chemical reaction during the charging and discharging process, which improves the utilisation rate of the active substance and enables the battery to output a higher capacity and enhance the performance of the battery.

6、 Good consistency: Tubular plate production process is relatively stable, can better control the quality and performance of the plate, so that the same batch of production of the battery plate between the consistency of good. In the battery pack, the performance difference of each single cell is smaller, which is conducive to improving the overall performance and service life of the battery pack, and reducing problems such as premature failure of the battery pack due to the difference of single cells.
