Nanocomposite Electrode

Project Description

The objective of the project is to manufacture 2D/0D architectured nanocomposites for high-energy-density and high-power-density Li-ion batteries from layered deposition of graphene and nanoparticles followed by laser induced shock compression (LSC).  LSC will generate well controlled defects/strain in graphene, nanoporosity, and three-dimensional connection between 2D/0D nanomaterials to facilitate the energy output and rate performance of batteries.
