In this work the coupled electrochemical-thermal model for a lithium-ion battery (LIB) based on porous electrode theory has been extended with contributions coming from exothermic side reactions based on an Arrhenius law to model abuse mechanisms, which could lead to a thermal runaway. ... 詳細を見る
The earlier work in our group has established that natural convection plays a dominant role in SLRFB. We used it to run a battery in which interestingly, the contents are agitated for brief spells when no current flows through it. The present work focuses on electrode configurations ... 詳細を見る
