摘要： Flexible lithium-ion batteries include patterned electrode assemblies configured to partition bending stresses when the lithium-ion battery is flexed by localizing high bending stresses. The patterned electrode assemblies can include a patterned current collector and active material or patterned active material formed on a current collector that is not patterned.

摘要： Aspects of the disclosure describe an energy storage device comprising a cathode, an anode, a separator, and an electrolyte. The anode comprises a support structure and an electrode layer disposed on the support structure. The electrode layer comprises 40-80% silicon, 15-40% graphite, 5-15% carbon black, 0-15% carboxymethyl cellulose (CMC), 0-5% styrene-butadiene rubber (SBR), and 5-20% poly(acrylic acid). The separator is disposed between the anode and cathode to prevent internal shorting of the energy storage device. The electrolyte allows movement of ions between the anode and cathode.

摘要： A method of manufacturing a three-dimensional electrochemical lithium battery includes forming a first electrode on an underlying layer comprising aerosolizing a first ink formulation comprising a slurry including nanoparticles or microparticles of a first active material and a binder, and depositing the slurry onto the underlying layer to form a first electrode layer. A permeable separator layer is formed on the first electrode by aerosolizing a polymer precursor solution, exposing the aerosolized polymer precursor solution to a first activating radiation source to form partially cured polymer spheres in the aerosolized stream, focusing and directing the aerosolized stream onto a substrate to form the permeable separator layer of the partially cured polymer spheres, and exposing the partially cured polymer spheres on the substrate to a second activating radiation source to fully cure the partially cured polymer spheres. A second electrode is formed on the permeable separator layer by aerosolizing a second ink formulation comprising a slurry including nanoparticles or microparticles of a second active material and a binder, and depositing the slurry onto the permeable separator layer.
