Abstract: A flexible and foldable lithium ion battery is disclosed having an operational bend radius of 180 degrees with no interruption in supply of electrical power. The lithium ion battery includes a high-elasticity separator sponge having a porosity of approximately 70% to approximately 90%. The separator is a polymer-based fiber mat having fibers with a submicron diameter. The separator sponge has a thickness in a range of approximately 5 to 50 microns, an air permeability of approximately 100 to approximately 300 s/100 ml, and a puncture resistance of approximately 350 to approximately 950 N. First and second electrodes are disposed on either side of the separator sponge and include active materials positioned on thin metal current collectors. A liquid electrolyte is absorbed by the separator sponge. The battery may be folded upon itself without loss of power.

Abstract: A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry. Non-gas evolving initiators are used for non-gas evolving in-situ polymerization of acrylate or allyl monomer-based QSE. The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.

Abstract: A pressure distribution mapping system includes a flexible M×N textile-based pressure sensor array. with first and second electrode textile layers and a piezoresistive fabric layer with a sheet resistance of at least 60 k-ohm/square positioned between the first and second electrode textile layers. Individual pressure sensors are formed by an intersection between a row electrically-conductive path and a column electrically-conductive path along with the portion of the piezoresistive layer positioned at the intersection. A measurement system measures the resistance of each pressure sensor of the pressure sensor array. The measurement system includes a reading module with first op-amps connected to each row and second op-amps connected to each column. Plural switches switch between pressure sensor-enabled and pressure sensor-disabled positions to minimize a bus line crosstalk effect during pressure sensor reading A processor scans each pressure sensor and generates a pressure distribution profile based on a measured resistance of each pressure sensor.
