Secondary Raw Materials for Sustainable Next-Generation Electrochemical Energy Conversion and Storage Systems

The year 2024 was the hottest on record, with global temperatures surpassing 1.5°C above pre-industrial levels for the first time [1]. This milestone highlights the urgent need to deploy clean energy technologies and sustainable materials to reach net-zero emissions by 2050.
A successful transition to renewables requires eco-friendly solutions for electrochemical energy conversion and storage, such as batteries, and supercapacitors [2]. Green strategies — like using secondary raw materials and bio-based resources — are key to enabling this shift.
Ore approach involves the synthesis of non-stoichiometric δ-MnO2 from manganese recovered from Brazilian mining tailings, offering a sustainable route to high-performance anode materials for next-generation batteries [3].
