PCT No. PCT/DE95/00112 Sec. 371 Date Apr. 22, 1996 Sec. 102(e) Date Apr. 22, 1996 PCT Filed Jan. 27, 1995 PCT Pub. No. WO95/22642 PCT Pub. Date Aug. 24, 1995A method for manufacturing a hardened lead storage battery electrode wherein fine, particulate solids, that are insoluble in lead, are incorporated into a lead matrix. The method includes the steps of incorporating solids, dissolved or suspended in an electrolyte, into a lead matrix such that shaping simultaneously occurs during the deposition of lead due to a suitable fashioning of a plurality of electrically conductive surface regions; vigorously agitating the electrolyte by introducing air through an apertured plate in the bottom of an electrolyte vessel providing an electro-chemical cell including a cathode and a Cu/Ta/Pt anode and an electrolyte solution including HBF4 and an electrolyte selected from PbO, Pb(OH)2 and PbCO3 or including a graphite anode and an electrolyte solution of Fe(BF4)2 and Fe(BF4)3. The electrolyte is prepared from a raw material selected from lead, waste material containing lead and desulfured lead storage battery electrolyte paste. The deposition is carried out at a current density of about 100 to about 2000 A/m2. |
