abstract = {Fast charging is one of the key requirements for
next-generation lithium-ion batteries, however, lithium-ion
diffusion rates of typical electrode materials are limited.
Nanosizing of active electrode material is a common strategy
to increase the effective lithium-ion diffusion transport
rate, but it also decreases the volumetric energy/power
density and stability of the battery. In this work, nickel
niobate NiNb2O6 is demonstrated for the first time as a new
intrinsic high-rate anode material for lithium-ion batteries
without the requirement of realizing nano-architectures. The
NiNb2O6 host crystal structure exhibits only a single type
of channel for lithium-ion intercalation and can be fully
lithiated with a capacity of about 244 mAh g−1 at low
current densities. Interestingly, a high diffusion
coefficient of 10−12 cm2 s−1 at 300 K enables fast
(dis)charging at high current densities resulting in high
capacities of 140 and 50 mAh g−1 for 10 and 100C
respectively. The minimal volume change during lithiation is
the origin of the stable reversible lithiation process in
NiNb2O6 and leads to $81\%$ capacity retention after
20 000 cycles at 100C. Finally, full cell systems against
LiFePO4 and Li[Ni0.8Co0.1Mn0.1]O2 (NCM811) cathodes
demonstrate the promising energy storage performance of
nickel niobate anodes in practical battery devices.},
