Abstract
1336601 Storage battery separators ELECTRIC POWER STORAGE Ltd 19 Jan 1971 [20 Jan 1970 7 Oct 1970] 2643/70 and 47703/70 Heading H1B [Also in Division B2] An electrode 10 for a lead-acid battery is formed with a porous separator envelope 31 of sintered plastics material closed at its bottom and side edges but open at the top to permit gas venting. Vertical ribs 33 on the inner surface of the envelope form passages 32 which facilitate gas venting and access of electrolyte to the electrode. In one method of forming the separator envelope on the electrode the latter, shown in chain-line in Fig. 1, is held between two metal combs 12, 13, each having nine prongs coated with P.T.F.E., the upper ends 25 of the combs being mounted on plates 17, 18 biased by springs surrounding bolts 19, 20 so that the combs pivot bosses 22, 23, 24 to grip the electrode. The pasted electrode mounted between the combs is heated to 240 C. and lowered into a fluidized bed of P.V.C. powder to the level 25 and held there for a predetermined time to obtain the desired coating thickness of P.V.C. On removal from the bed the assembly is heated at 240 C. to sinter the P.V.C. and the combs 12, 13 are withdrawn to leave the electrode 10 surrounded by the P.V.C. envelope 31. In a modification, flat fibrous separator pads are placed on the electrode surfaces before the envelope is formed thereon. In another method of forming the separator envelope, the combs 12, 13 are replaced by thin plates having vertical grooves, the plates being placed against the electrode surfaces so that the grooves face outwardly.
