Abstract Extensive efforts have been undertaken to develop and optimize newmaterials for lithium-ion batteries to address power and energy demands of mobile electronics and electric

cost, safety concerns, and deficiencies in energy density and calendar life. Advanced materialsprocessing techniques can contribute solutions to such issues. From that perspective, this work summarizes the materials-processing techniques used to fabricate the cathodes, anodes, and separatorsused in lithium-ion batteries.

2. Processing for Electrolytes

An electrolyte for lithium-ion batteries should be able to dissolve and dissociate into the solvent system, and the Li ions should be able to diffuse in the system with high mobility. Conventional electrolytes consist of lithium salts dissolved in organic solvents[5]. Propylene
