The increased use of portable electronic devices and electric vehicles has dramatically increased the demand for electrochemical energy storage devices with high energy and power densities. Graphite has been the most widely used anode material for Li-ion batteries for years. However, due to its low theoretical capacity (372 mAh/g), there have been significant efforts to develop new materials with enhanced energy densities to replace graphite. Graphene, a one-atom-thick hexagonal carbon array, has shown numerous advantages including superior electrical/thermal conductivity and high surface area. Therefore, it is a promising candidate as an anode material for high-power, high-energy density Li-ion batteries. This research program is designed for undergraduate students to learn about advanced graphene battery technologies. Through the research tasks, the undergraduate student will not learn only basic concepts of Li-ion battery system and energy storage mechanisms, but will also obtain experience of hand-on experiments for preparation of graphene-based electrodes and their performance tests toward the Li-ion battery.
