[0015] Example one:
[0016] The lead-silicon concentrating battery includes several electrode groups, electrolyte and conductive network. Several electrode groups are connected in series. Each electrode group is composed of several parallel positive electrodes, several parallel negative electrodes and separators. The separators are arranged in Between the positive electrode and the negative electrode, the electrolyte is a mixture of sulfuric acid, water, stabilizers, and additives, and a silicon material that has undergone hydroxylation treatment. The mixture is then mechanically stirred and ultrasonically stirred, and then a mixture of about 500 mesh is used. Emulsion filtered by a plastic screen.
[0017] Electrode preparation: the support material and conductive network of the positive and negative reaction materials of the battery adopt a network structure composed of electrodeposited lead on the plastic surface; the positive reaction material adopts a mixture of lead, lead m...
