Can high capacity conversion anodes be used for Li-ion batteries?

High capacity conversion anodes for Li-ion batteries are thoroughly reviewed. The invention of alloying is crucial for high capacity conversion anodes. The reversible capacity can be increased by applying nano- and hybrid-architectures. Theoretical studies on mechanisms of the conversion reactions have been reviewed.

Is ZRS 2 a promising anode material for Li-ion batteries?

ZrS 2 has been shown as a promising anode material in Li-ion batteries by both experimental and theoretical studies due to its higher carrier mobility and current density at room temperature compared to MoS 2 in applications of low power devices (j), (k), (l), (m).

Does morphology affect reversible capacity of Li-ion batteries?

Kharbachi et al. [486a] studied the morphology effects in MgH 2 anode for Li-ion batteries and found a general trend of the increase of the reversible capacity as a function of particle size. However, failure mechanism was reaction-rate dependent and compatibility of the complex SEI formation regarding the highly dispersive LiH matrix.

What are conversion/alloy active materials?

Conversion/alloy active materials offer high specific capacities and often also fast lithium-ion diffusion and reaction kinetics, which are required for high C-rates and application in high-energy and high-power devices such as battery electric vehicles.

What are conversion-alloy active materials used for?

Otherwise, conversion-alloy active materials are used as a seed layer or interlayer for a homogeneous Li deposition or to mitigate the formation and growth of the SEI, respectively.

Are conversion-type transition-metal compounds suitable for Next-Generation libs?

Conversion-type transition-metal compounds are attractive anodes for next-generation LIBs because of their diverse compositions and high theoretical specific capacities. Here, we provide an overview of the recent development of some representative conversion-type anode materials (CTAMs) in LIBs.
