AsianScientist (Apr. 26, 2017) – In a study published in Chem, researchers from China have developed a way to capture atmospheric nitrogen and store energy in a battery at the same time. As the most abundant gas in Earth''s atmosphere, nitrogen is an attractive option as a source of renewable energy.
example, such a zinc-nitrogen hybrid flow battery (Zn N battery, ZNB) has an ideal theoretical energy density of 871 Wh L 1 at the solubility limit of KNO 3 in the water (38 g/ 100 mL, 25 °C), which is much higher than that of the lead battery, vanadium redox battery, Zn Br 2 battery, Zn MnO 2, and many others (see Figure 1b). Besides, in ...
