Rapid population and economic growth, excessive use of fossil fuels, and climate change have contributed to a serious turn towards environmental management and sustainability. The agricultural sector is a big contributor to (lignocellulosic) waste, which accumulates in landfills and ultimately gets burned, polluting the environment. In response to the current climate-change crisis, policymakers and researchers are, respectively, encouraging and seeking ways of creating value-added products from generated waste.

- A Ni-based metal-organic framework (Ni-MOF) was synthesized using a microwave-assisted method and transformed into carbon with high surface area through carbonization and acid treatment, resulting in AT-Ni/MOFDC.
- Characterization techniques showed that AT-Ni/MOFDC had smaller nanoparticle sizes and structural defects, leading to improved battery performance, with a specific capacity of 199 mAh/g compared to 92 mAh/g for its precursor.
- The study demonstrates the hybrid energy storage capabilities of AT-Ni/MOFDC in a battery-type device, achieving high energy and power densities, as well as excellent cycling stability, paving the way for advanced energy storage technologies.
