Li-air, rechargeable, solid-state batteries using graphene and boron nitride aerogel matrices.*

The recent explosion of research on Li-Air batteries has provided new insights into developing more efficient air cathodes. Graphene and boron nitride aerogel matrix is anticipated to be an ideal candidate to produce a high throughput air-breathing system. We developed a Li-Air battery model that accounts for efficient O$_{\mathrm{2}}$ throughput. These unique aerogel matrices exhibit the ability to orient the O$_{\mathrm{2}}$ passing through and keep out H$_{\mathrm{2}}$O, CO$_{\mathrm{2}}$, and N$_{\mathrm{2}}$. Thus, the solid-state cells demonstrate a long cycle life, thermal stability, and high rechargeable characteristics. These cells also show an explicit discharge capacity with a constant discharge current density of 0.1mA/cm$^{\mathrm{2}}$.
