Abstract
Flexible aluminum-air batteries have great prospects in wearable devices and various engineering applications. However, it is still a huge challenge for flexible aluminum-air batteries to operate stable under severe cold conditions. The key to solving this problem is to develop freeze-resistant electrolytes with high mechanical performance. Therefore, a novel PVA/BC-EG gel electrolyte for flexible aluminum-air battery was prepared in this study. The crystallization resistance and abundant hydrogen bonds of the PVA/BC-EG electrolytes endow them with freeze-resistant and high mechanical performance. The conductivity and elongation of the electrolytes can reach 21.383 mS/cm and 441.529% even at -20 ℃. The flexible aluminum-air batteries assembled with the PVA/BC-EG electrolytes can still maintain excellent electrochemical characteristics after fatigue-stretching 2000 times under subzero conditions.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
