(US5871862-A)      A paste for a lead-acid electrochemical cell comprises at least one lead-containing composition, a paste vehicle and a paste additive of polyvinylsulphonic acid or its salts.    Also claimed are: (i) a lead-acid cell as above comprising a housing containing a positive current collector (30) on which is a positive paste (54) as claimed above and a negative current collector (40) and negative paste (60) and a cell in which the paste additive is claimed in the negative paste. (ii) a plate structure having the paste above. (iii) a method for forming the plate structure comprising applying the paste to the collector. (iv) a method of forming the lead-acid cell above in which the paste additive is used in either the positive or negative collector.    USE -   As lead-acid electrochemical cells for vehicles, with start-light-ignition functions    ADVANTAGE -   Charge capacity is increased, internal stability improved and cycle life extended. Paste application and adherence is improved.
