Porous Si anode materials for lithium rechargeable batteries
Si anode materials for lithium rechargeable batteries have received much attention due to their high capacity. The Si itself can alloy with lithium up to Li4.4Si, corresponding to 4212 mAh/ g (4.4Li + Si 4 Li4.4Si). However, the large volume expansion of over 300% due to the formation of various LixSiy phases generates enormous mechanical stress within the ionic character material, which become...
متن کاملStructural modulation of lithium metal-electrolyte interface with three-dimensional metallic interlayer for high-performance lithium metal batteries
The use of lithium (Li) metal anodes has been reconsidered because of the necessity for a higher energy density in secondary batteries. However, Li metal anodes suffer from 'dead' Li formation and surface deactivation which consequently form a porous layer of redundant Li aggregates. In this work, a fibrous metal felt (FMF) as a three-dimensional conductive interlayer was introduced between the...
متن کاملA nanoporous metal recuperated MnO2 anode for lithium ion batteries.
Lithium-ion batteries (LIBs) have been intensively studied to meet the increased demands for the high energy density of portable electronics and electric vehicles. The low specific capacity of the conventional graphite based anodes is one of the key factors that limit the capacity of LIBs. Transition metal oxides, such as NiO, MnO2 and Fe3O4, are known to be promising anode materials that are e...
متن کاملFunctional membrane separators for next-generation high-energy rechargeable batteries
Themembrane separator is a key component in a liquid-electrolyte battery for electrically separating the cathode and the anode, meanwhile ensuring ionic transport between them. Besides these basic requirements, endowing the separator with specific beneficial functions is now being paid great attention because it provides an important alternative approach for the development of batteries, partic...
متن کاملBulk antimony sulfide with excellent cycle stability as next-generation anode for lithium-ion batteries
Nanomaterials as anode for lithium-ion batteries (LIB) have gained widespread interest in the research community. However, scaling up and processibility are bottlenecks to further commercialization of these materials. Here, we report that bulk antimony sulfide with a size of 10-20 μm exhibits a high capacity and stable cycling of 800 mAh g(-1). Mechanical and chemical stabilities of the electro...
