Development Of Flexible Batteries Using Nano-Carbons And Polymers, Zhiqian Wang

Dissertations

Flexible electronics such as wearable equipment, displays, cell phones and smart cards require flexible power sources like batteries. In this thesis, the development of flexible batteries and supercapacitors are presented. Different types of flexible batteries including zinc carbon batteries, primary alkaline batteries, secondary alkaline batteries and zinc air cells are presented, These were designed, fabricated and improved using polymers and nano-carbons like carbon nanotubes (CNTs). CNTs are found to be effective as conductive additives compared to the traditional graphite. Purification is important to remove impurities that lead to side reactions/ corrosions. However, further treatment like carboxylation lead to higher electric …
