Green and sustainable electrochemical energy storage (EES) devices are critical for addressing the problem of limited energy resources and environmental pollution. A series of rechargeable batteries, metal–air cells, and supercapacitors have been widely studied because of their high energy densities and considerable cycle retention. Emerging as a promising electrode material for these devices, MnO₂ has drawn great attention due to its abundance, environmental sustainability, low cost, and high activity. This review provides a systematic overview of environmentally benign MnO₂ syntheses and representative applications in various electrochemical storage devices including metal-ion batteries, Zn–air batteries, and supercapacitors. A major emphasis is placed on ameliorating the environmental impact of MnO₂ materials via green syntheses and the eco-friendly and safe properties of advanced aqueous energy storage devices with MnO₂-based electrodes. This review should provide insights into how intrinsic structure, modification of compositions or facets, and morphology influence the electrochemical performance of MnO₂ electrodes. Additionally, current challenges and future research opportunities are also discussed to facilitate further improvements in this field.
