AI Customer ServiceHydrogen peroxide of 30% was used in Zn-H 2 O 2 batteries. All battery tests were conducted by Neware battery system. Activated carbon and Co/N-CNS samples were used as low-rate and high-rate catalysts for H 2 O 2 decomposition, respectively.
The leaching yield of Mg and Zn leveled off after 15 min and reached 7 and 25%, respectively. Thus, under the tested conditions in the presence of hydrogen peroxide, it is possible to efficiently leach valuable metals from spent lithium-ion batteries with very high leaching yields even after short leaching times.
Metal-air batteries have high capacities and power densities, but performance is limited in the absence of oxygen. Hydrogen peroxide not only has oxygen storage capacity of ∼1,600 times that of air but is also in some ways more convenient for storage and transportation than high-pressure cylinders.
Our findings hold promise for all metal–peroxide batteries with high theoretical energy densities (e.g., Mg–H 2 O 2, Al–H 2 O 2, and Fe–H 2 O 2). This research was partially supported by the Israel Innovation Authority “KAMIN” grant No 82461. It also received partial funding from the JNF Canada Inc. award.
However, their performance is vastly hampered by the sluggish kinetics of oxygen redox reactions at the air electrode. Herein, a rechargeable metal–hydrogen peroxide battery is introduced that is air-free and uses onsite generated and reduced hydrogen peroxide (H 2 O 2) as an oxygen source for charging and discharging.
Here, we propose a new alkaline ZAB design based on in situ formation and oxidation of hydrogen peroxide (HO 2− in alkaline solution) on an air electrode (Scheme 1), henceforth referred to as a Zn–peroxide battery (ZPB).
