NON-WOVEN MATERIAL FOR SEPARATORS OF LEAD STORAGE BATTERIES

摘要

FIELD: electric engineering. SUBSTANCE: material has two outer and intermediate fiber layers which are connected to one another. Outer layers are made from mix of heavy-shrinkage polyester fibers and viscose fibers in ratio of 80: 20 by weight. Linear density of polyester fibers is 0.33 tacks, they are keen to thermal shrinkage at 190-220 C. Linear density of viscose fibers is 0.31 tacks. Intermediate layer is made from polyester fibers which linear density is 0.17 tacks. EFFECT: decreased electric resistance, increased initial discharge voltage when storage batteries are used under low temperatures.
