LEAD ACID STORAGE BATTERY

摘要

PROBLEM TO BE SOLVED: To improve cycle life by having good adhesion property between a grid and an active material and good connecting property between active material particles even when used in idling stop or under an over-charge control condition and suppressing sulfation in a negative electrode. SOLUTION: The lead acid storage battery contains at least one kind selected from bismuth, antimony and calcium in a positive electrode substrate surface composed of lead-calcium based alloy and/or in positive electrode active material. At the same time, at least one kind selected from aluminum ion, selenium ion and titanium ion is contained in the electrolyte. COPYRIGHT: (C)2009,JPO&INPIT
