A novel solution combustion synthesis of nanoscale spinel-structured Co3O4 powder was proposed in this work. The obtained material was composed of loosely arranged nanoparticles whose average diameter was about 36 nm. The as-prepared cobalt oxide powder was also tested as the anode material for Li-ion batteries and revealed specific capacities of 1060 and 533 mAh·g−1 after 100 cycles at charge–discharge current densities of 100 and 500 mA·g−1, respectively. Moreover, electrochemical measurements indicate that even though the synthesized nanomaterial possesses a low active surface area, it exhibits a relatively high specific capacity measured at 100 mA·g−1 after 100 cycles and a quite good rate capability at current densities between 50 and 5000 mA·g−1.

Combustion Reactivity

A mesoporous mesh Co3O4/C composite was synthesized by using a combustion synthesis (SCS) method with mixed fuel solution. The combustion reactivity can be controlled through adjusting the fuel composition. During combustion reaction, with the release of gas and the growth of Co3O4 particles, residual carbon and Co3O4 formed porous network that significantly improved the rate performance of the Co3O4/C composite. After 200 cycles, the Co3O4/C composite delivered reversible discharge/charge specific capacity of 1120/1025, 965/930, 889/837, and 772/706 mAh g-1 at current densities of 1 C, 2 C, 3 C, and 5 C, respectively. This work provides a guide for the synthesis of anode materials by using SCS with low energy consumption.

Silicon has been investigated as promising anode materials in lithium-ion batteries due to its high theoretical specific capacity. Nonetheless, high-capacity Si nanoparticles succumb to limited electrical conductivity, drastic volume change, and harsh aggregation upon cycling. In this paper, a unique multicoated composite is fabricated through innovative, simple, atmospheric pressure, and cost-effective atmospheric pressure aerosol-assisted vapor deposition (APAAVD). The fabrication method is reported for the first time with a well-distributed graphene nanoplatelets/nano-silicon composite layer through the processing with an organic solvent. The plane of the layers facilitates high rate capability, whereas the voids between the layers buffer volume expansion of silicon for good cycling performance. The multicoated composite anode (10 wt.% Si) presents a specific capacity of ~500 mAh g-1 at 0.17 A/g and capacity retention of 85.8 % after 500 discharge/charge cycles. The facile method preserves the combined advantages of atmospheric pressure chemical vapor deposition and aerosol-assisted chemical vapor deposition, offering an encouraging research arena for initial laboratory tests in rechargeable Li-ion batteries. Besides, two approaches for the presentation of cyclic discharge/charge patterns are proposed with generalized algorithms through linear algebra.

The present paper focuses on a nanostructured SnCo alloy electrochemically prepared by template method in view of its use as anode material alternative to graphite in lithium-ion batteries. The fabrication of SnCo nanowire arrays was carried out by potentiostatic co-deposition of the two metals by using nanostructured anodic alumina membranes as template. Electrochemical tests on lithiation-delithiation of these SnCo electrodes in conventional organic electrolyte (EC:DMC LiPF6) at 30°C showed that their specific capacity was stable for about the first 12 cycles at a value near to the theoretical one for Li22Sn5 and, hence, progressively decayed.
