Scalable Solvent-Based Fabrication of Thermo-Responsive Polymer Nanocomposites for Battery Safety Regulation

چکیده

Improving lithium-ion battery (LIB) safety remains a challenging task when compared with the tremendous progress made in their performance recent years. Embedding thermo-responsive polymer switching materials (TRPS) into LIB cells has been proved to be promising strategy provide consistent thermal abuse protections at coin-cell level. However, it is unrealistic achieve large-scale applications without further demonstration high-capacity pouch cells. Here, we employed tungsten carbide as novel conductive filler, and successfully overcame intrinsic processing difficulty of polyethylene matrix scalable solvent-based method obtain ultra-thin, uniform, highly TRPS. Moreover, by integrating TRPS directly electrodes, no extra fabrication facilities or processes are required for making As result, multi-layer electrochemical protection function were fabricated using industry-relevant manufacturing techniques, which brings one step real application scenarios.

Stimuli-responsive mechanically adaptive polymer nanocomposites.

A new series of biomimetic stimuli-responsive nanocomposites, which change their mechanical properties upon exposure to physiological conditions, was prepared and investigated. The materials were produced by introducing percolating networks of cellulose nanofibers or "whiskers" derived from tunicates into poly(vinyl acetate) (PVAc), poly(butyl methacrylate) (PBMA), and blends of these polymers,...

Scalable fabrication of immunosensors based on carbon nanotube polymer composites.

In this work we present the fabrication and characterization of immunosensors based on polystyrene (PS)-multiwalled carbon nanotube (MWCNT) composites. The electrochemical properties of the sensors have been investigated and show that the surface area is increased upon addition of the MWCNT-PS layer. Furthermore, a plasma activation process is used to partially remove the PS and expose the MWCN...

A scalable fabrication process of polymer microneedles

While polymer microneedles may easily be fabricated by casting a solution in a mold, either centrifugation or vacuumizing is needed to pull the viscous polymer solution into the microholes of the mold. We report a novel process to fabricate polymer microneedles with a one-sided vacuum using a ceramic mold that is breathable but water impermeable. A polymer solution containing polyvinyl alcohol ...
