چکیده

In the quest to increase battery performance, nanostructuring electrodes gives access architectures with electrical conductivity and solid-state diffusion regimes not accessible traditional based on aggregated spherical microparticles, while often also contributing cyclability of otherwise unstable active materials. This work describes where material current collector are formed as a single nanostructured composite network, consisting macroscopic fabrics carbon nanotube fibers covered conformal MoS2 grown preferentially aligned over graphitic layers, without metallic or any conductive polymeric additives. The fabric CNTF/MoS2 retain high toughness show out-of-plane 1.2 S/m, above threshold avoid transport-limited performance (1 S/m), control nanocomposite LIB (0.1 S/m) produced from dispersed nanocarbons. Cycled against Li, they specific capacity 0.7 Ah/g along appreciable rate capability cycling stability in low (108% retention after 50 cycles at 0.1 A/g) well density (89 % 250 1 A/g). flexible, tensile up J/g, two orders magnitude higher than conventional regular material, full-electrode state art different densities.

Solution-grown silicon nanowires for lithium-ion battery anodes.

Composite electrodes composed of silicon nanowires synthesized using the supercritical fluid-liquid-solid (SFLS) method mixed with amorphous carbon or carbon nanotubes were evaluated as Li-ion battery anodes. Carbon coating of the silicon nanowires using the pyrolysis of sugar was found to be crucial for making good electronic contact to the material. Using multiwalled carbon nanotubes as the c...

Growth of conformal graphene cages on micrometre-sized silicon particles as stable battery anodes

Nanostructuring has been shown to be fruitful in addressing the problems of high-capacity Si anodes. However, issues with the high cost and poor Coulombic e ciencies of nanostructured Si still need to be resolved. Si microparticles are a low-cost alternative but, unlike Si nanoparticles, su er from unavoidable particle fracture during electrochemical cycling, thus making stable cycling in a rea...

Mesoporous CNT@TiO2-C Nanocable with Extremely Durable High Rate Capability for Lithium-Ion Battery Anodes

A well-designed nanostructure CNT@TiO2-C with fine anatase TiO2 particle (< 8 nm), good electronic conducting network (inner CNT core and outer carbon layer), and mesoporous structure was prepared by a simple and green one-pot hydrothermal reaction. The utilization of glucose in the hydrothermal process not only solves the interfacial incompatibility between CNTs and titanate sol and controls t...

Toward efficient binders for Li-ion battery Si-based anodes: polyacrylic acid.

Si-based Li-ion battery anodes offer specific capacity an order of magnitude beyond that of conventional graphite. However, the formation of stable Si anodes is a challenge because of significant volume changes occurring during their electrochemical alloying and dealloying with Li. Binder selection and optimization may allow significant improvements in the stability of Si-based anodes. Most stu...
