Abstract

PURPOSE:To improve quality stability, acid-resistance, and life of battery by press- sticking two sheets of separator paper with a special reinforcing mixture applied inbetween. CONSTITUTION:The separator 9 is composed by applying an inorganic layer 10 of dried mixture of acid-proof synthetic resin (MMA emulsion) and acid-proof inorganic powder (white carbon) between sheets of separator paper 1, 1. Manufacture of this separator 9 is performed as follows. Sheets of separator paper 1, 1 which is manufactured from a mixture of synthetic pulp, synthetic fibre, inorganic powder, etc., are supplied from rotatable reels. Aqueous solution 5, a mixture of MMA emulsion, etc., in a mixing vessel 3 is fed to roll-coaters 2 and applied to one side of each sheet of paper 1, 1. The composite is then press-rolled by a set of press- rollers 2, conveyed to and dry-hardened by a dry-hardening furnace 7, and finally cut into sizes 8.
