Benign-by-design sustainable batteries

Conventional battery technologies require temperature-controlled calcination process to produce active materials, N-methyl-2-pyrrolidone-assisted slurry coating process to make electrodes and utilizes heavy metal foil current collectors, which give rise to cost, material-and energy consumption and environmental issues.

In this regard, this project aims to develop the very first, lightweight, freestanding, metal-free current collector, cellulose-based paper electrodes, using an unconventional, ultrafast (one minute), energy-efficient pyrolysis method and sustainable materials.

This project will develop a benign-by-design principal for the realization of sustainable batteries that combines improved energy efficiencies, maximizes the use of renewable natural resources with economic and environmental soundness, which opens new horizons to develop a resource and energy efficient, sustainable society.
