Thin, Flexible and Loaded Li-ion Batteries Based on CNT Tissues Serving as Current Collectors

Electrochemical systems are being thought as the solution for the vast demand for high energy density in both portable and stationary devices. Such systems hold a great promise, while pressure on researchers grows as the need for more “juice” in mobile device (from small hand held electronic to large mobile systems as EV) dramatically increase as technology is rapidly evolving.

In this talk, we will describe a possible transition from copper and aluminum current collectors into carbon nano tube (CNT) tissues. Such transition may substantially reduce the overall weight of the battery, and at the same time would allow more volume in the cells to be subsequently loaded with the active electrode materials. We will describe the processes needed for implementing CNT tissues in Li-ion batteries, as well as overcoming the massive irreversible capacity associated with the buildup of the solid electrolyte interphase (SEI) onto both the graphite and the CNT surfaces. Copper electroplating onto the CNT fabric predominately at top surface of the tissue will be discussed as well.
