NOVELTY - Modified lithium tantalate modified graphene nanomaterial (I), is new. USE - The modified lithium tantalate modified graphene nanomaterial is used as lithium electrode protection component in lithium battery (claimed) for mobile device and electric automobile. ADVANTAGE - The modified lithium tantalate modified graphene nano material improves the dendritic crystal growth of lithium metal cathode the circulation process caused by poor cycle performance, compared with only using the cathode alkene, the cycle performance is improved by 104%. It provides many active sites for lithium metal conversion and deposition, reduces the occurrence of the secondary reaction of the lithium metal in the charging and discharging process, improves the stability and multiplying power performance of the electrode, and is doped with a small amount of transition metal elements. DETAILED DESCRIPTION - Modified lithium tantalate modified graphene nanomaterial of formula LiMxTa1-xO3 (I), is new, where M is transition metal elements, preferably Ni2+, Mn2+, Ag+, Zn2+ and Sr3+. x = 0-0.5. An INDEPENDENT CLAIM is included for preparing (I).
