Oxide Spinels

Lithium manganese oxide spinels are attractive materials for lithium-ion battery cathodes due to their capability for high voltage application paired with a three-dimensional conductive pathway that can allow for improved lithium insertion and deinsertion kinetics. However, this material suffers from limited cyclability as a result of the energy barriers for removing lithium from the octahedral sites and capacity fading as a result of manganese dissociation. This work incorporates a multiple doping strategy for selecting capacity distribution across various voltage regimes. The resulting electrochemical cells are able to produce useful capacity at 5.2 V, 4.7 V, 4.1 V, and 2.75 V. Additionally, materials synthesized in a laboratory setting and via large scale production via licensing with no cobalt content has resulted in capacities exceeding 200 mAh/g. These materials achieve 75% capacity retention at 3C vs. C/10 discharge down to 2.75 V.

Main Components

A novel finding, that the calcined weathered stones (denoted as CWS) can be employed as the anode materials for lithium ion batteries (LIBs), is reported for the first time in this work. Under the air conditions, the weathered stones were respectively calcined at 400ºC (sample a), 600ºC (sample b) and 800ºC (sample c) for 2 h, with an intention to examine the influence of the calcination temperature on the physicochemical properties of the resultant materials. XRD results indicated that the main components of all the final products were SiO2. And the SEM images demonstrated that all the as-prepared samples were irregular and larger particles with no evident crystal structure. The results of the electrochemical measurements revealed that the initial discharge capacity of sample b was about 104 mAh g-1 at the current density of 100 mA g-1, which was remarkably larger than that of the employed pure SiO2 (50 mAh g-1). Interestingly, after 20 cycles, the discharge capacity of sample b was still maintained as high as 70 mAh g-1, along with a capacity retention rate of about 70%. Although the discharge capacity reported here was lower as compared to the currently reported anode materials, this novel finding was very meaningful to the large scale production of anode materials, mainly due to the rather lower cost and abundant resources as well as the simple preparation process.

Average Size

Particle size effects on the electrochemical performance of the CuO particles toward lithium are essential. In this work, a low-cost, large-scale production but simple approach has been developed to fabricate CuO nanoparticles with an average size in ~ 130 nm through thermolysis of Cu ( OH )2 precursors. As anode materials for lithium ion batteries (LIBs), the CuO nanoparticles deliver a high reversible capacity of 540 mAh g-1 over 100 cycles at 0.5 C. It also exhibits a rate capacity of 405 mAh g-1 at 2 C. These results suggest that the facile synthetic method of producing the CuO nanoparticles can enhance cycle performance, superior to that of some different sizes of the CuO nanoparticles and many reported CuO -based anodes.
