High conductivity pristine copper particles and carbon coated Li 2 ZnTi 3 O 8 composite (Li 2 ZnTi 3 O 8 /C@Cu) is prepared by one-step sol-gel method followed by high temperature pyrolysis. Amorphous carbon coating layer reveals a thickness of 2.0-8.0 nm on the outer surface of Li 2 ZnTi 3 O 8 active grains, which improves the electronic conductivity and charge transfer rate of primary and secondary particles. Moreover, copper particles between particles could enhance the electronic transmission at large current densities and decrease diffusion resistance. As a result, Li 2 ZnTi 3 O 8 /C@Cu composite shows lower electrochemical polarization and quicker kinetic behavior compared to Li 2 ZnTi 3 O 8 /C. Cycled at 1000 mA g-1 , 2000 mA g-1 , and 3000 mA g-1 , Li 2 ZnTi 3 O 8 /C@Cu can deliver a reversible capacity of 124.4 mAh g-1 , 90.8 mAh g-1 , and 79.1 mAh g-1 after 1000 cycles, which is much higher than the values of 70.7 mAh g-1 , 75.5 mAh g-1 , and 52.1 mAh g-1 obtained by Li 2 ZnTi 3 O 8 /C. In addition to higher specific capacity, electrode polarization and cycle stability have been improved after adding copper particles. The improved electrochemical properties of Li 2 ZnTi 3 O 8 /C@Cu composite are attributed to the combination of copper additive and carbon layer.

“…Carbonaceous materials possess good electronic conductivity and high-rate capability and can preserve the structural integrity of active materials, thereby giving enhanced cyclability and rate capacity of the resulting hybrid composites. A variety of modifications of ZFO with carbonaceous materials have been exploited: surface carbon coating [31], graphene as substrate with active nanomaterials decorating [102,103], growing, or anchoring on surfaces [25,55], embedding in carbon matrix [34] or graphene nanosheets-wrapped active material particles [32] until the use of sacrificial templates [104][105][106][107][108][109][110] (Figure 8).…”

ZnFe2O4, a Green and High-Capacity Anode Material for Lithium-Ion Batteries: A Review

Ferrites, a broad class of ceramic oxides, possess intriguing physico-chemical properties, mainly due to their unique structural features, that, during these last 50–60 years, made them the materials of choice for many different applications. They are, indeed, applied as inductors, high-frequency materials, for electric field suppression, as catalysts and sensors, in nanomedicine for magneto-fluid hyperthermia and magnetic resonance imaging, and, more recently, in electrochemistry. In particular, ZnFe2O4 and its solid solutions are drawing scientists’ attention for the application as anode materials for lithium-ion batteries (LIBs). The main reasons are found in the low cost, abundance, and environmental friendliness of both Zn and Fe precursors, high surface-to-volume ratio, relatively short path for Li-ion diffusion, low working voltage of about 1.5 V for lithium extraction, and the high theoretical specific capacity (1072 mA h g−1). However, some drawbacks are represented by fast capacity fading and poor rate capability, resulting from a low electronic conductivity, severe agglomeration, and large volume change during lithiation/delithiation processes. In this review, the main synthesis methods of spinels will be briefly discussed before presenting the most recent and promising electrochemical results on ZnFe2O4 obtained with peculiar morphologies/architectures or as composites, which represent the focus of this review.
