Brightening up every child's future through affordable renewable energyZhilin Wang, Singapore Finalist, 16-18
My project is about creating a rechargeable zinc air battery to replace expensive Li-Ion batteries currently used to store renewable energy. I discovered that an aerogel made of graphene and carbon nanotubes can improve activities of oxygen redox reactions, lowering energy loss and improving battery efficiency. Through studying various perimeters to optimize catalytic activity, I seek to make zinc air batteries more practical affordable methods to store locally generated renewable energy in developing countries. This will hopefully provide access to reliable lighting and the tools of education for more.
