“…[1] In particular, nanopainting with carbon has recently been found effective for improving cyclability, where carbon functions as a physical buffering layer for the large volume change (cushion effect). [7,9,14,[21][22][23] For example, the recent commercial SONY tin-based anode has been characterized by Whittingham and coworkers to be basically composed of amorphous SnCo nanoparticles coated with graphitic carbon. [24] Despite the physical appeal of these procedures, our recent studies show that either design strategy alone leads to only limited improvement in cyclability of SnO 2 -based anode materials.…”

A proof‐of‐concept structural design is demonstrated for high‐capacity lithium‐ion batteries anode materials by multistep synthesis of coaxial SnO2@carbon hollow nanospheres. This material integrates two beneficial features: hollow structure and carbon nanopainting. When evaluated for reversible lithium storage, these functional materials manifest excellent cycling performance and rate capabilities.

“…In addition to the utilization of conductive carbonaceous materials to combine with Si, core/shell structure with Si core were utilized for the formation of stable SEI via pyrolysis of organic precursors [33][34][35][36]. For example, Si nanoparticles were coated with carbon by the hydrothermal carbonization of glucose to obtain Si@SiO x /C nanocomposite [34].…”

Silicon-based nanomaterials for lithium-ion batteries

Silicon-based nanomaterials have been of scientific and commercial interest in lithium-ion batteries due to the low cost, low toxicity, and high specific capacity with an order of magnitude beyond that of conventional graphite. The poor capacity retention, caused by pulverization of Si during cycling, triggers researchers and engineers to explore better battery materials. This review summarizes recent work in improving Si-based anode materials via different approaches from diverse Si nanostructures, Si/metal nanocomposites, to Si/C nanocomposites, and also offers perspectives of the Si-based anode materials. Lithium ion batteries (LIBs) as attractive energy storage devices have become ubiquitous power sources for mobile electronics. Increasing power and energy requirements for applications such as electric and hybrid electric vehicles, have spurred intense interest in developing high capacity electrode materials to surpass the capacities of electrode materials used in current LIBs [17]. To achieve the requirements, much research work has been performed on new anode materials with high specific capacities. Silicon has attracted increasing attention as a potential high-capacity anode material because of numerous appealing features such as high theoretical specific capacity of 4212 mAh g -1 , higher safety and stability than graphite (lithiated silicon is more stable in typical electrolytes than lithiated graphite). Si anode materials, however, suffer from some drawbacks involving the drastic volume change (larger than 300%) during the alloying/de-alloying reactions with Li [8], the intrinsic low electrical conductivity, and the unstable solid electrolyte interphase (SEI) formed in the common electrolyte of LiPF 6 . These limitations still challenge the investigation and development on identification of higher capacity for the next generation LIBs. Various advances in Si morphology have been achieved in the past years, demonstrating that nanostructured Si-based materials particularly offer superior properties in LIBs.In this review, we address the recent developments in optimizing Si-based materials via diverse Si nanostructures, Si/metal nanocomposites, and Si/C nanocomposites. In addition, we offer some perspectives for the design of better Si nanomaterials.

We report the synthesis of porous LiFePO 4 /NiP composite nanospheres and their application in rechargeable lithium-ion batteries. A simple one-step spraying technique was developed to prepare LiFePO 4 /NiP composite nanospheres with an electrical conductivity 10 3 10 4 times that of bulk particles of LiFePO 4 . Electrochemical measurements show that LiFePO 4 nanospheres with a uniform loading of 0.86 wt% 1.50 wt% NiP exhibit high discharge capacity, good cycling reversibility, and low apparent activation energies. The superior electrode performance of the as-prepared composite nanospheres results from the greatly enhanced electrical conductivity and porous structure of the materials.
