Abstract:
      With the rapid development of electric vehicle industry, the safety and fast charging of lithium ion batteries have attracted more and more attention. Graphite, as commercial anode material for lithium-ion batteries, has a great potential safety hazard of internal short-circuit caused by the lithium plating due to the low intercalationSpotential (~0 V), and is not suitable for fast charging batteries. LiEuTiO4 with a layered perovskite structure has intercalationSpotential of about 0.8 V and actual capacity of over 200 mAh/g, which can avoid the occurrence of lithium plating and will keep high energy density and rate performance, thus hopefully become the ideal anode for safe fast-charging power battery for electric vehicles. In this paper, the current research status of LiEuTiO4 is summarized, including molecular structure, lithium-storage mechanism, preparation method and problems to be solved, etc.
