Hydrophobic silica colloid electrolyte holds promise for safer lithium-oxygen batteries
(PHYSorg.com Chemistry)

Traditional lithium-ion (Li-ion) batteries cannot satisfy increasing demand for large-scale electricity consumption. Rechargeable aprotic lithium-oxygen (Li-O2) batteries have become potential candidates due to their ultrahigh theoretical energy density, which is about 10 times that of Li-ion batteries. Lithium metal as an anode is one of the key factors in obtaining such high specific capacity.
