Despite carbonaceous materials are widely employed as commercial negative electrodes for lithium ion battery, an urge requirement for new electrode materials that meet the needs of high energy density, long cycle life, low cost and safety is still underway. A number of cobalt-based compounds (Co(OH)2, Co3O4, CoN, CoS, CoP, NiCo2O4, etc.) have been developed over the past years as promising anode materials...
Alkaline zinc manganese dioxide (Zn–MnO2) batteries are widely used in everyday life. Recycling of waste alkaline Zn–MnO2 batteries has always been a hot environmental concern. In this study, a simple and cost-effective process for synthesizing Mn3O4/carbon nanotube (CNT) nanocomposites from recycled alkaline Zn–MnO2 batteries is presented. Manganese oxide was recovered from spent Zn–MnO2 battery...
