SEPARATOR FOR NON-AQUEOUS BATTERIES, NON-AQUEOUS BATTERY USING SAME, AND PRODUCTION METHOD FOR SEPARATOR FOR NON-AQUEOUS BATTERIES |
摘要 |
Provided is a separator for non-aqueous batteries not only having shutdown property but also achieving both higher output and short-circuit resistance. The separator comprising a laminate comprising: a low melting-point polymer fiber layer (A) having a melting point of 100 to 200 °C, the low melting-point polymer fiber layer (A) comprising nanofibers having a fiber diameter of 1000 nm or smaller and formed from the low melting-point polymer; and a heat-resistant polymer fiber layer (B) positioned on the low melting-point polymer fiber layer (A) and comprising a high melting-point polymer having a melting point over 200 °C or a heat infusible polymer, the heat-resistant polymer fiber layer (B) comprising a mixture of nanofibers having a fiber diameter of 1000 nm or smaller and non-nanofibers having a fiber diameter over 1000 nm and both formed from heat-resistant polymer. |
