A winding battery with asymmetric
hybrid meshed pole plates, same-direction electrodes and dual-membrane
safety valve comprises a battery shell and a
battery cell and is characterized in that the
battery cell forms a cylindrical body by winding a positive pole plate, a negative pole plate and a separator by a
battery cell winding shaft, wherein the separator is arranged between the positive pole plate and the negative pole plate, a
positive current collection disc and a negative current collection disc are respectively arranged at tops of two ends of the battery
cell, a tab is arranged at a top end of one side, near to the
positive current collection disc, of the positive pole plate and is equal to the positive pole plate in length, a spiral groove is formed in the current collection disc, a negative terminal is led to a positive terminal direction of the battery by an
electrode terminal protection sleeve, the
electrode terminal protection sleeve is arranged on a side surface of the battery shell, the negative pole plate is the
hybrid meshed
electrode, a high-strength conductive
fiber mesh is used as a bottom plate, and
metal oxide coating layers such as
ruthenium oxide, which are arranged in a dot way, and a negative active substance are arranged on the bottom plate. The winding has the advantages that by a special end-surface current collection structure and the
hybrid meshed electrodes, the
current conduction capability is effectively improved; and meanwhile, the battery has characteristic of a
supercapacitor, the dual-membrane
safety valve is
safer, and the performance of the battery is better.
