چکیده
Alloying materials (e.g., Si, Ge, Sn, Sb, and so on) are promising anode for next-generation lithium-ion batteries (LIBs) sodium-ion (SIBs) due to their high capacity, suitable working voltage, earth abundance, environmental friendliness, non-toxicity. Although some important breakthroughs have been reported recently these materials, dramatic volume change during alloying/dealloying causes severe pulverization, leading poor cycling stability safety risks. the nanoengineering of alloys can mitigate volumetric expansion extent, there remain other drawbacks, such as low initial Columbic efficiency energy density. Porous microscale comprised nanoparticles nanopores inherit micro- nanoproperties, that lithiation/sodiation be better accommodated by porous structure consequently release stress improve stability. Herein, recent progress alloying-type LIBs SIBs is reviewed summarizing Li Na storage mechanisms, challenges associated with different common fabrication methods, relationship between electrochemical properties in SIBs. Finally, prospects discussed provide guidance future research commercial development
