Abstract
Thermal characterization and diagnosis are critical for the whole-life-cycle safety of lithium-ion batteries (LIBs). However, conventional techniques are time-delayed and discontinuous due to the sealed structure and intricate mechanisms of LIB. Herein we report an innovative non-invasive approach for whole-life-cycle thermal monitoring of LIBs. For the first time, our approach combines ultrasonic measurements and heat transfer analysis to diagnose the average temperature and heat capacity accurately, with an error of 2.81%. We furthermore link ultrasonic features to specific failure stages from early incubation to the onset of thermal runaway (TR), paving a new ultrasonic way to interpret the failure modes and early-warn the TR of LIB. Using the ultrasonic features, the TR warning can be 32.47 min ahead compared with commonly-used voltage clues. The ultrasound-enabled approaches are attractive to multiple stages in battery life, including the first- and second-life thermal stability evaluation, regular monitoring, failure analysis and end-of-life early warning.
期刊介绍:
Energy & Environmental Science, a peer-reviewed scientific journal, publishes original research and review articles covering interdisciplinary topics in the (bio)chemical and (bio)physical sciences, as well as chemical engineering disciplines. Published monthly by the Royal Society of Chemistry (RSC), a not-for-profit publisher, Energy & Environmental Science is recognized as a leading journal. It boasts an impressive impact factor of 8.500 as of 2009, ranking 8th among 140 journals in the category "Chemistry, Multidisciplinary," second among 71 journals in "Energy & Fuels," second among 128 journals in "Engineering, Chemical," and first among 181 scientific journals in "Environmental Sciences."
Energy & Environmental Science publishes various types of articles, including Research Papers (original scientific work), Review Articles, Perspectives, and Minireviews (feature review-type articles of broad interest), Communications (original scientific work of an urgent nature), Opinions (personal, often speculative viewpoints or hypotheses on current topics), and Analysis Articles (in-depth examination of energy-related issues).
