In this paper, a new reaction-diffusion model, coupling the reversible electrochemical reaction, Lithium (Li) diffusion, and bending, is proposed to investigate the curvature, neutral axis movement, and stress in bilayer electrode. Bending curvature and stress, for the first time, are analytically and numerically investigated relate to both the diffusion and the reversible electrochemical reaction. The results reveal that the reversible electrochemical reaction retards the lithiation process, leading to the slowing down of diffusion process.

Polymer–metal–polymer composite films are widely used in packaging, building, and cooling, and more recently as envelopes for pouch lithium-ion batteries (LIBs). The influences of heat seal temperature and dwell time on the heat seal strength (HSS) of five different multilayer films were investigated by T-peel testing. The failure modes were observed and analyzed by digital optical microscopy. Heat-sealing temperature and dwell time interacted and simultaneously influenced the HSS. Temperature was confirmed as the primary factor while dwell time was secondary.

Temperature-dependent
modulus of glass fiber/epoxy composite laminates were studied at temperatures
ranging from room temperature up to 120℃. The storage modulus, loss
modulus, loss factor, and glass transition temperature of two layer-up composite
laminates were investigated by dynamic mechanic analysis (DMA). Static flexural
modulus was also measured by control force mode in DMA. A new and simple temperature-dependent
model both for the dynamic storage modulus and static flexural modulus was developed.
