报告摘要:
Commercial Li-ion batteries use graphite and metal oxides as negative and positive electrodes through Li intercalation reaction. The capacity is limited by the reaction nature: intercalation. The quantity of Li-ion can be intercalated in one compound without destroying the structure is limited. In contrary, conversion reactions are one way to step forward larger capacities at the anode.Beside solid-state storage of hydrogen with metallic or complex hydrides, electrochemical storage is one of the most advanced commercial applications developed so far, for hydrides with well-known alkaline Ni-Metal Hydrides (Ni-MH) batteries. Recently, a breakthrough was realized by demonstrating that metal or complex hydrides can be also used for lithium-ion batteries either as negative electrode or solid electrolytes. We here give some examples to use metallic or complex hydrides as negative electrode and solid electrolyte, development of half- and full-cells using the combination of solid hydride-based electrolytes and metal hydride anodes that pave the way to future hydride-based efficient electrochemical storage systems.
