The increasing global population, and ever-growing energy demand calls for game-changing research strategy for electrochemical energy storage. Substantial progress in battery technology is essential if we are to succeed in an energy transition towards a more carbon-neutral society. Rechargeable aluminum batteries have recently reached great attention due to its excellent safety, natural abundance of aluminum and as well as its high theoretical capacity. The highly natural reactivity of Al2S3 with moisture and oxygen faces challenges in high quality battery applications. To control target Al2S3 material preparation we demonstrate a molecular approach by single molecular synthesis. By introducing a chelating thiol-containing ligand to suitable aluminum sources the reactivity and stability of as-prepared molecular precursors [Al2(SC2H4N(Me)C2H4S)3] and [AlH(SC2H4N(Me)C2H4S)] can be controlled. Fully characterized single molecular precursors enable a direct and sustainable material preparation by preformed Al-S bonds in thermal decomposition experiments.
