Abstract: Rechargeable lthium-ian btteries (LIBs) are important electrochemical energy storage devices fox consumer lectronicsand emerging eletricalhybrid vehicles. However, onc of the fomidable callenges is to develop ultrafast changing LIBS with therate capability an least one order of magnitude higher than that of the cumently commercialized LIBs In this allk I will present outrecent developtment of ulrtfaet changing LIBs by the rtinal design of maerials First of al I will discus the prutocol 10 rtivallyyrow elongated titanate nanotubes with length up W tens of micronelers by a siming hydroshemal method. The mechanscal force-driven stiming proess sychronously improving the difusion and surfice reaction rate of itamate nanoenystal growth in sohutionphase is the reason for kenghening the titanate manotubes vin an onented atachment mechanism This protool to synthesizeelongated nanostnuctures can be extended to other nanostnuctured systems, opening up new opportunitics for manufacturing advancedfunctional materiak for highb-performance cnergy storage devices. Then, we wil show how a robust theedimensional ntworkarchitcture with anti-agregatian property is fomed for long-time eyeting through the assembly of continuous one-dimensionalTiOtanotubes which provides direet and rapid inekectrto tanspont pathways and adequate decroue-eletrolyle contact and shortlithium in difusicon distance comparing with oather manosinucturs. Fmally, the future trends and perspectives for the ultrafastrechargeible LIBS are discussed. Comtimued mapid progress in this area is ssential and urgent t endow I IBs with ulinafast chargingcapabilty to meet huge demands in the near future
