Abstract
Due to its remarkable theoretical energy density and capacity density, the Al-air battery is regarded as the most competitive potential candidate for next-generation energy storage systems. However, attributed to its enormous liquid electrolyte storage and transportation infrastructure, the conventional Al-air battery is not appropriate for miniature applications. To get around the issue of pumps providing a continuous electrolyte flow for AABs, we created a microfluidic Al-air battery. Without pumps, the special capillary action in the paper tubes could carry electrolytes constantly and automatically. This battery produced a remarkable output of 16.74mW/cm2 and an open circuit potential (OCP) of more than 1.6V using an alkaline electrolyte. The energy density and capacity density of this battery were 350.96mWh/g at 20mA/cm2 and 963.31mAh/g, respectively. As a result, we suggested a commendable plan for compact and basic Al-air cells as reliable power sources.
