Lithium-ion batteries are widely used in laptop computers, cell phones, and electric vehicles. Using liquid electrolytes requires the use of additional materials and poses inherent fire hazard. All-solid-state lithium-ion batteries utilize solid electrolytes and are much safer and efficient, but much more expensive to produce. This project made an effort to develop a low-cost method for fabricating all-solid-state lithium-ion batteries. LiCoO2 cathodes were prepared using high temperature sintering. LiLaTiO3 solid electrolyte was prepared using sol-gel reaction and was deposited on LiCoO2 cathode disk via spin-coating. The effectiveness methodology was tested by evaluating the condition cathode-solid electrolyte system and testing an all-solid-state battery.
