This research studies the definition, invention, history, development, and future of rechargeable battery technology, as well as the environmental impacts they have had on the world. Key stages in the development of rechargeable batteries are noted, from the invention of the “Voltaic Pile” by Alessandro Volta in the 1790s through to modern developments such as lithium-ion and lithium-polymer batteries. Developing technologies, such as lithium sulphur batteries are assessed in comparison to current batteries as to whether they are viable and what the obstacles are in terms of their development. Modern rechargeable battery technology is assessed in terms of environmental impact to determine whether they are actually a viable solution to disposable batteries and fossil fuels or whether they cause more harm to the environment.
