| 논문초록 | To date, various approaches have been reported for replacing rigid components of typical batteries with elastic materials. Little attention, however, is paid to stretchable separator membranes that can not only prevent internal short circuit but also provide an ionic conducting pathway between electrodes under physical deformation. Herein, a poly(styrene-b-butadiene-b-styrene) block copolymer-based stretchable separator membrane was fabricated by the nonsolvent-induced phase separation (NIPS). The various mechanical properties and porous structures can be obtained by using different polymer concentration and tuning the affinity among major components of NIPS. The stretchable separator membrane exhibited a high stretchability of around 270% strain and porous structure having porosity of 61%. Thus, its potential application as stretchable separator membrane for deformable energy devices was demonstrated by applying to organic/aqueous electrolyte based rechargeable lithium-ion batteries. |
