Superiorities of lead-calcium alloys for storage battery construction

Recent investigations, conducted at the Bell Telephone Laboratories and elsewhere, have demonstrated that the lead-antimony alloys almost universally employed in storage cell construction are far from ideal for the purpose from the elect rochemical standpoint. It has been shown that in the course of normal operation of the present type cell, antimony is leached out of the positive electrode, passes through the solution and deposits on the negative. where it promotes “localaction” and self-discharge. Also, it has been demonst rated that stibine is generated in perce ptible amounts by the present type battery on over-charge.
