 Abstract

Due to the ascending of energy consumption and the development of renewable energy technologies, energy storage techniques has become a significant solution to match the increasing electricity generation. Among all the energy storage systems, the rechargeable battery is one of the most widely used technologies in industry and daily life.
Recently, rresearchers have been focusing on Li-S batteries for their high specific capacity (1675 mAh/g) and energy density (2600 Wh/kg). However, the polysulfides dissolution problem in the cell induces a fast capacity degradation issue which impedes Li-S battery to be brought into realistic commercial market.
In this thesis, attempts will be made to improve Li-S batteries by the incorporation of high specific surface area materials in the sulfur electrode to enhance adsorption of polysulfides as to prevent active material loss. Furthermore, the working principle of the lithium sulfur battery will be investigated through in-situ Neutron Depth Profiling.
