Abstract: Lithium based batteries plays an irreplaceable role in today's information age. The most widely used batteries nowadays are the solid lithium ion batteries(LIB), which can be found in portable devices like laptop, hand phone, calculator, and cameras and so on. However, one big disadvantage for LIB is the long charging time and restricted output power. One alternative to overcome the disadvantage is the lithium solvated electron solution battery. For the lithium solvated electron solution battery, the electrodes are composed of liquid solutions, and they can be replaced immediately after discharging process. Such design allow for rapid replenishing of the battery stack and high energy storage capacity. In the battery, the anode is composed of lithium solvated electrons solution (Li-SES) . The Li-SES is prepared by dissolving metallic lithium in a solution of poly-aromatic hydrocarbon (such as biphenyl and naphthalene) in tetrahydrofuran (THF). And the cathode is composed of other carbon containing structures dissolved in solvent. During the discharging process, the lithium in anode will escape from the anode and recombine with the carbon structures in cathode. In this thesis, all the carbon containing structures are planar polycyclic aromatic hydrocarbons. We want to investigate the interaction mechanism between lithium and hydrocarbons.
