Abstract
Electrolyte-infiltrated composite electrode includes an electrolyte component consisting of a polymer matrix with ceramic nanoparticles embedded in the matrix to form a networking structure of electrolyte. Suitable ceramic nanoparticles have the basic formula LiLaZrO(LLZO) and its derivatives such as AlLiLaZrTaNbOwhere x ranges from 0 to 0.85, y ranges from 0 to 0.50 and z ranges from 0 to 0.75, wherein at least one of x, y and z is not equal to 0. The networking structure of the electrolyte establishes an effective lithium-ion transport pathway in the electrode and strengthens the contact between electrode layer and solid-state electrolyte resulting in higher lithium-ion electrochemical cell's cycling stability and longer battery life. Sold-state electrolytes incorporating the ceramic particles demonstrate improved performance. Large dimensional electrolyte-infiltrated composite electrode sheets can be used in all solid-state lithium electrochemical pouch cells which can be assembled into battery packs.
