Y uegang Zhang is determined to make a better battery. The physicist and materials scientist started his career developing new ways to manufacture and use carbon nanotubes. In 2008, while at Lawrence Berkeley National Laboratory, he found himself drawn to perfecting a promisingbut challengingbattery technology based on lithium–sulfur chemistry. He tested a variety of carbon nanomaterials to m...

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...

Abstract Growth in the Li-ion battery market continues to accelerate, driven primarily by increasing need for economic energy storage electric vehicles. Electrode manufacture slurry casting is first main step cell production but much of manufacturing optimisation based on trial and error, know-how individual expertise. Advancing science that underpins electrode critical adding value chain. Over...
