Multi-cell storage devices (e.g. lithium-ion batteries (LIBs)) stand as
one of the most important components which are widely used in
battery energy storage technology for renewable energy power system, hybrid electric vehicles and portable electronic devices due
to its high energy density and low manufacturing cost. In recent
years, there has been an explosion of developing new and multifunctional nanomaterials with particular interest to electrode nanomaterials (nano-MnO2, nano-LiMn2O4, etc.). In such case, size-dependent
mechanical-diffusion responses analysis of multilayered composite
nanostructure under non-uniform concentration in-service environment will become significantly important. To address the problem, a
multilayered composite nanoplates account for diffusion impedance
and elastic wave impedance at the interface is considered in this
research. Governing equations involving with size-dependent characteristic lengths and material constant ratio of each two adjacent
layers are formulated, and then, a semi-analytical approach via the
Laplace transformation is applied. Then, the obtained solutions are
applied to bilayered composite nanoplates, and the influences of
size effects and material constants ratio on structural responses are
emphatically discussed to provide guidelines on and new insights
into the optimal design and management of mechanical responses
and vibration control of nano-sized multi-cell storage devices under
non-uniform concentration environment, especially for the nanocoating. |
