All earlier lead-acid batteries were made with antimony alloy lead grids. Their perceived disadvantages: (1) Relatively high water consumption; (2) High price of antimony. Calcium alloy was introduced to overcome disadvantages (1) and (2). However, calcium alloy has its own inherent disadvantages. That insulating layer is one of them.

Lead - Antimony alloys have high corrosion resistance in most enviroments. They form a protective, impermeable film even faster than pure lead and in some cases even faster than chemical lead. It is found that except in the presence of florine compunds, 6% antimonial lead is more resistant to corrosion than is soft lead. 6% Antimony, 92% Lead this is by far the most popular with target shooters.
