Electrochemical Performance of Porous Carbon/Tin Composite Anodes for SodiumIon and LithiumIon Batteries
The electrochemical performance of mesoporous carbon (C)/tin (Sn) anodes in Na-ion and Li-ion batteries is systematically investigated. The mesoporous C/Sn anodes in a Na-ion battery shows similar cycling stability but lower capacity and poorer rate capability than that in a Li-ion battery. The desodiation potentials of Sn anodes are approximately 0.21 V lower than delithiation potentials. The ...
متن کاملHollow Nanostructured Anode Materials for Li-Ion Batteries
Hollow nanostructured anode materials lie at the heart of research relating to Li-ion batteries, which require high capacity, high rate capability, and high safety. The higher capacity and higher rate capability for hollow nanostructured anode materials than that for the bulk counterparts can be attributed to their higher surface area, shorter path length for Li(+) transport, and more freedom f...
متن کاملPorous 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 کاملSponge-like porous carbon/tin composite anode materials for lithium ion batteries
A novel sponge-like porous C/Sn composite is synthesized by dispersing SnO2 nanoparticles into a softtemplate polymer matrix followed by carbonization. The mesoporous C/Sn anodes can deliver a capacity as high as 1300mAh g 1 after 450 charge/discharge cycles, and provide a capacity of 180mAh g 1 even at 4000 mA g 1 charge/discharge current density. An extra reversible capacity over the theoreti...
متن کاملAnode for Sodium-Ion Batteries
DOI: 10.1002/aenm.201500174 The continuous pulverization of alloy anodes during repeated sodiation/desodiation cycles is the major reason for the faster capacity decay. However, if these elements can form a compound (such as Sn 4 P 3 ) after each Na extraction, the pulverization of these elements can be partially repaired and the accumulation of pulverization can be terminated. Therefore, we ca...
