Challenges in the Development of High-Energy Lithium-ion Batteries
The School of Mechanical and Materials Engineering is hosting a seminar presented by Jianming Zheng, Staff Scientist, Pacific Northwest National Laboratory.
Abstract:
Lithium-ion batteries (LIBs) are the state-of-the-art energy storage systems dominating the consumer electronic devices and electric vehicles (EVs) markets. With the state-of-the-art LIBs deployed in automobile industry, the driving range of EVs is still far behind those of conventional vehicles using internal combustion engines. Therefore, there is an urgent need to overcome current limitation of LIBs in energy and power density, to prolong the driving range and shorten the recharging time. In this presentation, I will share with our recent results on the development of high-energy-density LIBs, lithium sulfur batteries and lithium metal batteries, focusing on the materials development and the stabilization of electrode interface.
