All-solid-state lithium-ion batteries utilize solid electrolytes and are much safer and efficient when compared to lihtium-ion batteries tha use liquid electrolyte, but are 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. Different methods of LiCoO2 sol and LiLaTiO3 sol deposition were tested for removing surface pores from cathode disks. 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.
