Technical consultants Ryan is an award-winning engineer and business leader with more than 20 years’ experience in the High-Performance, Heavy-Duty and Off-Highway Automotive markets. Prominent in the development of Power Electronics, Electric Motors and Drives (PEMD) for these demanding applications, he has successfully founded, scaled and exited three businesses in the electric vehicle space. He is currently CEO of eTech49 Limited, an advisory business specialising in disruptive hardware technology in PEMD. In addition, he is Chairman of EV North, an industry group representing the booming EV industry in the north of England, a board member of the North East LEP and an adviser to a number of corporations. Danson Joseph has had a varied career in the electrical power industry, having worked in areas ranging from systems engineering of photovoltaic power plants to developing the battery packs for Jaguar Land Rover’s I-Pace SUV. With a PhD in electrical machines from the University of Witwatersrand in South Africa, Danson has focused on developing battery systems for automotive use. After completing the I-Pace project he formed Danecca, a battery development company with a focus on prototyping and small-scale production work, as well as testing and verifying cells and packs destined for mass production. Dr Nabeel Shirazee graduated from Leicester University in 1990, where he studied electrical and electronic engineering. An MSc in magnetic engineering followed at Cardiff University, where he continued his studies, earning a PhD and developing a permanent magnetic lifting system that has been patented by the university. His interest in magnetics led to a patented magnetic levitation system that was awarded the World’s No 1 Invention prize at INPEX in the USA. In 1999, he founded Electronica, a magnetics research and design consultancy. Since then, he has been involved in various projects, including the design of an actuator motor for a British aerospace company. He has also licensed the levitation technology in France. Ryan Maughan Danson Joseph Dr Nabeel Shirazee formed a continuous heat transfer path. This ice-template method is simple, environmentally friendly and cost-effective for large-scale production. The structure of the h-BN aerogel varied a lot according to the amount of h-BN, with a 20 wt% loading leading to a condensed layered structure with shorter distances between layers compared with a 10 wt% h-BN loading. At a loading of 30%, the parallel layer structure changes to a honeycomb structure that is less effective at thermal management. “We found that the h-BN constructed by the ice-template method with varying temperature gradients showed structural differences in different directions,” said Prof Zhang. “Generally, structure determines performance, and different structures in different directions mean a greater spread of performance. By creating a composite with paraffin wax [h-BN/PW], we could achieve excellent anti-leakage performance and ultra-fast heat dissipation performance in lithium- ion batteries.” The composite with a 20 wt% loading of h-BN can guarantee a highly ordered network, and exhibited high thermal conductivity of 1.86 W/m/K – four times that of randomly dispersed h-BN involved PW and nearly eight times greater than that of bare PW. The optimal thermal conductive composites demonstrated ultra-fast heat dissipation as well as leakage resistance for lithium-ion batteries. The heat generated by the batteries can be effectively transferred under the working state and the surface temperature kept 6.9 C lower with a continuous charge- discharge rate of 2 to 5 C compared with that of the bare one, which illustrated considerable potential for industrial thermal management.
