“…Additionally, the reversible specific capacity of NLTO-NF at 0.1, 0.2, 0.5, 1.0, 2.0, 3.0, and 4.0 A g –1 reaches 265, 219, 183, 157, 135, 124, and 118 mAh g –1 , respectively (Figure c). Compared with other perovskite-type or Ti-based materials (Figure e and Table S2), − ,− the NLTO-NF anode exhibits appreciable reversible specific capacity and superior rate performance. Such admirable rate capability profits from the excellent conductive N-doped carbon skeleton and unique multichannel structure, which highly promote the electron transportation and migration of Li + .…”

High-capacity" graphite and "zero-strain" spinel Li 4 Ti 5 O 12 (LTO) occupy the majority market of anode materials for Li + storage in commercial applications. Nevertheless, their intrinsic drawbacks including the unsafe potential of graphite and unsatisfactory capacity of LTO limit the further development of lithium-ion batteries (LIBs), which is unable to satisfy the ever-increasing demands. Here, a novel Na 0.35 La 0.55 TiO 3 perovskite embedded in multichannel carbon fibers (NLTO-NF) is rationally designed and synthesized through an electrospinning method. It not only has the advantages of a respectable specific capacity of 265 mAh g −1 at 0.1 A g −1 and superb rate capability, but it also possesses the zero-strain characteristic. Impressively, an ultralong cycling life with 96.3% capacity retention after 9000 cycles at 2 A g −1 is achieved in the half cell, and 90.3% of capacity retention ratio is obtained after even 2500 cycles at 1 A g −1 in the coupled LiFePO 4 /NLTO-NF full cell. This study introduces a new member with excellent performance to the zero-strain materials family for next-generation LIBs.

Introducing large-radius elements in layered perovskite for low-voltage lithium storage

Abstract: A layered perovskite oxide, LiSmTO4, has been designed as an anode for high-performance lithium-ion batteries, delivering low-voltage lithium storage. The doping of large-radius Sm suppress the tilts and facilitate lithium ion mobility.
