Summary:Scalable, Three-dimensional, Anisotropic Wood-Carbon Directly from Trees for Advanced Batteries (Flow, Biodegradable, Li metal) Chaoji Chen, Ying Zhang, Amy Gong, Wei Luo, Chao Jia, Liangbing Hu Department of Materials Science and Engineering, University of Maryland College Park As the demand for advanced energy storage techniques and devices grows, the energy storage market is seeking for higher performance, longer lifetime, better safety and environmental friendliness. The competitions for higher performance are mainly focused on developing new materials, whereas there has been limited works that are dedicated to the electrode structure design and engineering. In this talk, I will discuss our effort on the development of three-dimensional (3D) anisotropic carbon having long, well aligned channels derived directly from wood (Figure 1). I will discuss the following topics: • Wood carbon library from different types of wood (hardwood, softwood); • Engineered wood based carbon to tune the porosity, density and tortuosity; • Wood carbon for bio-degradable batteries;1 • Wood carbon for Li metal batteries using the guiding channels; • Wood carbon for flow batteries.
