Paper, 'On a new electrical storage battery' by Henry Sutton Sutton writes that 'no system of electric supply can be con­sidered as perfect until some means is used to so store the force generated that it may be drawn off equally and regularly, and this whether the generator be on or off [...] All the present systems on storing electricity depend on certain chemical changes produced by electrolysis.' He relays the results of a series of investigations into a new electrical storage battery which consists of ' a porous pot containing dilute hydric sulphate and a sheet of lead, in an outer vessel containing a sheet of lead in solution of acetate of lead, the plate in the porous pot being made the positive electrode'.
