Beschreibung
Zusammenfassung:	PURPOSE:To increase drop impact strength and tensile strength and to increase liquid absorbing amount by using a specific inorganic material as the base material of a composite material of a separator for a satellite-use battery, and adding polytetrafluoroethylene as a binder and carboxymethylcellulose or polyolefin latex as an additive to the inorganic material. CONSTITUTION:An inorganic material such as potassium titanate, zirconia, and silicon carbide is used as the base material of a composite material of a separator for a satellite-use battery. Polytetrafluoroethylene (PTFE) is used as a binder and carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), or polyolefin latex is used as an additive. The drop impact strength and tensile strength of the composite material are increased, liquid absorbing amount is increased, weight is decreased, and bubble pressure is increased.
