The problem of storage, and release of thermal energy is an important challenge in various industrial fields. Several systems for thermal energy storage exist like phase change materials (PCM) and thermochemical storage [1]. The first system usually addresses short term storage (day ... En savoir plus

Stresses Due to Intercalation of Non-Spherical Lithium Storage Particles

R. Purkayastha[1], R. McMeeking[2]
[1]Cambridge University, Cambridge, UK
[2]University of California, Santa Barbara, CA, USA

Due to computational considerations most models of lithium storage particles in batteries incorporate spherical particles. However most storage particles used in battery electrodes tend to be irregular in shape with sharp edges and extended aspect ratios. The change of the relative ... En savoir plus

The increasing demand for large battery packs, driven by the expanding markets for electric vehicles (EVs) and grid-scale energy storage system, necessitates the development rapid battery pack development pipelines such as simulation. We present an integrated multiscale simulation ... En savoir plus

Reliability and Temperature Testing of PVDF-based Piezoelectric Energy harvesters.

Chandana Ravikumar¹, Vytautas Markevicius¹
¹Kaunas University of Technology, Lithuania (Europe)

During usage, storage, and transportation, electronic products often become affected by a few unwanted adverse effects of the surrounding environment that compromise their working performance, reliability, and device life. There is evidence that environmental effects cause 52% of such ... En savoir plus
