Agenda & Speakers:
1:00 pm Introduction and Welcome
1:05 pm Selection of Battery Chemistry and Charging Algorithm for IOT Devices, Naoki Matsumura, Intel Corp.
IOT devices expect batteries to have long battery life and cycle life because they may be used in areas where battery replacement is not easy. This session talks about the importance of impedance for longer battery life and methods to extend battery cycle life through battery charging algorithm. These are expected to reduce the cost of ownership as it enables less battery replacement.
Bio: Naoki Matsumura is a senior battery technologist at Intel Corporation, responsible for technical assessment of new battery technologies, charging algorithms and battery sourcing for consumer electronics, drones and Internet of Things. Prior to that, Naoki held battery research/development roles at Panasonic. Naoki earned his MS in Energy Science from Kyoto University and holds many patents.
1:40 pm Lithium-ion Battery and Beyond Lithium-ion Battery for Transportation/Grid Storage Applications, Gao Liu, Lawrence Berkeley National Laboratory
The rapid developments of lithium-ion battery technology in the past decade or so has ushered the electric vesicles into the mass market. Bay area EV company Tesla has played a catalytic role in this process. This talk will cover both the scientific developments as well as technology road map of lithium-ion battery, which enables the electric drive and reaches out to even broader grid energy storage applications. The talk will also discuss the futures of energy storage beyond the current lithium-ion chemistry, which is currently undertaken in the speaker’s lab.
Bio: Dr. Gao Liu is the Group Leader of the Applied Energy Materials Group in the Energy Storage and Distributed Resources Division at Lawrence Berkeley National Laboratory, specialized in materials and energy storage R&D. Dr. Liu has led research projects for the U.S. Department of Energy and industry. He has over 100 peer-reviewed publications and over 20 patents and patent applications. He has received numerous awards from his work on electrochemical energy storage materials and systems. The most recent awards include R&D100 Award in 2013 for the conductive polymer for lithium-ion battery application, and FMC Scientific Achievement Award in 2014 for the understanding fundamentals of prelithiation, and R&D 100 Award in 2015 for the high capacity lithium-ion anode design.
2:15 pm Triboelectric Nanogenerator for Next Generation Mechanical Energy Harvesting, Myeong-Lok Seol, NASA Ames Research Center
Demand for mobile power source is increasing with the growth of wireless sensor network, mobile healthcare devices, and internet-of-things (IoT). Most of the small electronic components use battery as the sole power source, but all batteries have a limited lifetime and require costly recharging and replacement. Mechanical energy harvesting is a technique that converts ambient mechanical energy sources, such as vibration, wind, and motion, into useful electrical energy. Triboelectric nanogenerator (TENG) is a recently developed mechanical energy harvester that is based on triboelectricity. Triboelectricity has been generally considered a harmful phenomenon because it often causes breakdown of electronic circuits and natural fires. However, in terms of energy harvesting, the strong power is an advantage when properly controlled and collected. In this seminar, the background and basic principles of TENG will be explained first. Next, analysis results on the effects of Mars environment on TENG performance will be introduced. In addition, all-printed TENG will be introduced that can be autonomously manufactured in space.
Bio: Myeong-Lok Seol is a research scientist at NASA Ames Research Center. His research interests include energy harvesting and nanotechnology-enabled electronic devices. Currently, he is developing triboelectric nanogenerator for space applications and all-printed energy harvesters. He received the B.S.degree in 2010 and the Ph.D. degree in 2016 from Korea Advanced Institute of Science and Technology (KAIST), Korea. He has published 55 international journal articles, has presented 7 international conference, and has received 8 patents.
