Abstract
Official abstract text for this publication.
Provided is a positive electrode grid for lead acid batteries, and a lead acid battery including the grid. The grid includes a lead alloy containing calcium and tin. The lead alloy has a calcium content of 0.10 mass % or less, and a tin content of 2.3 mass % or less, and a lattice constant of 4.9470 Å or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A positive electrode grid for lead acid batteries, comprising a lead alloy containing calcium and tin, the lead alloy having a calcium content of 0.10 mass % or less, the lead alloy having a tin content of 2.3 mass % or less, the lead alloy having a lattice constant of 4.9470 Å or less. 2. The positive electrode grid for lead acid batteries of claim 1 , wherein the tin content in the lead alloy exceeds 1.6 mass %. 3. The positive electrode grid for lead acid batteries of claim 1 , wherein the lead alloy has a Vickers hardness of 8 or more. 4. A lead acid battery, comprising a positive electrode plate, a negative electrode plate, a separator interposed between the positive electrode plate and the negative electrode plate, and an electrolyte including an aqueous sulfuric acid solution, wherein the positive electrode plate comprises the positive electrode grid of claim 1 .
