Energy Storage @ PNNL—Gaining Insight into Lithium-Ion Battery Degradation
Webinar presented by PNNL materials scientist Qian Huang
11 a.m. (PT), Thursday, November 3, 2022
| Battery degradation/reliability, which is directly related to its lifetime and safety performance, depends not only on chemistry, but also on complex physical-chemical processes under diverse operating conditions. Motivated by PNNL's reliability investigation on lithium-ion batteries (LIBs) for stationary application, this presentation will shed light on the mechanism of LIB degradation using a calorimetric approach. In particular, a methodology for in-situ heat measurement of commercial LIBs under grid services is being developed in order to disclose the relationship between thermal characteristics and the degradation/reliability of LIBs and to reinforce the development of the LIB state-of-health model. |
