Abstract:
A lead acid electric storage battery uses conventional lead-acid secondary battery chemistry. The battery may be a sealed battery, an unsealed battery or a conventional multi-cell battery. The battery has a set of positive battery grids (plates) which are constructed with a body portion o stamped f thin titanium metal having a thickness preferably in the range 0.1 mm to 0.9 mm and most preferably 3 mm to 4 mm. The titanium is coated, on all sides, with titanium sub-oxide, a conductive ceramic. Typically the battery would have over 250 grids in a 12 inch long battery case.

Claim (Index 4):
A lead-acid battery comprising a plurality of positive and negative battery grids with separators therebetween; (a) at least some of said positive grids being lead-free titanium grids; (b) said titanium grids having a stamped metal body portion and said grids having a thickness of less than 0.9 mm and not being a foil; (c) each of said titanium grids forming a plane having an imaginary line perpendicular thereto, said battery (d) said grids having a protective coating selected from the group consisting of titanium suboxide Magneli phase having the general formula Ti.sub.x O.sub.y, wherein the ratio of y to x is less than 2.selected from the group consisting of Ti.sub.4 O.sub.7, Ti.sub.5 O.sub.9, Ti.sub.6 O.sub.11, Ti.sub.7 O.sub.13, Ti.sub.8 O.sub.15 and Ti.sub.9 O.sub.7. (e) and a coating of lead on said titanium subdioxide coating.
