The growing demand for sustainable energy solutions has underscored the importance of critical minerals in shaping the future of energy storage. It is essential to implement initiatives that diversify supply chains, invest in recycling technologies, create alternative materials, and improve mining methods. The all-solid-state lithium-ion battery (aSSLIBs) using critical minerals aims to address energy storage limitations, supply chain risks, environmental concerns, climate change, and energy security. Unlike conventional liquid electrolyte-based LIBs, which suffer from thermal instability, flammability, leakage, and limited electrochemical windows. aSSLIBs, however, eliminate these risks by utilising solid electrolytes (SEs), which exhibit better ionic conductivities, reduced safety hazards, and improved electrochemical performance. We aim to utilise critical minerals in aSSLIBs and provide recommendations and roadmaps to address key performance parameters such as ionic conductivity, energy density, and cycling stability. Numerous research efforts have been conducted to develop suitable solid-state electrolytes, and considerable progress has been made, particularly for garnet-type SEs. Nonetheless, the garnet-type SE still faces several critical challenges. The work focuses on the ionic conductivity of garnet electrolytes as well as the interfaces between electrodes and SEs and cathode active materials. a concise explanation of the garnet structure, the synthesis techniques for bulk, thin-film, and composite garnet SEs is presented. The goal of this study is to provide a basic understanding of the latest developments in the energy storage sector, which may help realise useful garnet-based aSSLBs. Furthermore, future advancements and alternative approaches to addressing these challenges will be discussed to enhance the understanding of garnet electrolytes cathode active materials utilising critical minerals and promote their practical application in solid-state batteries.
