Energy storage mechanism of antimony-based materials

Can antimony materials be used in commercial production?

The composite modification means can realize more considerable electrochemical performance enhancement [5, 58]. Therefore, choosing pure antimony material may be one of the first choices for commercial production. In the sequel, we present applications of Sb-based anode materials and their derivatives and discuss their practical feasibility.

Is antimony sulfide a good anode material?

Owing to its high theoretical specific capacity, effective working voltage, and abundant raw materials, antimony sulfide (Sb 2 S 3) was regarded as one promising anode material for electrochemical energy conversion and storage, especially regarding alkali-ion (Li +, Na +, and K +) batteries.

What is the theoretical capacity of antimony selenides?

The theoretical capacity of sodium storage contributed by the resulting material of the above two-step reaction is 670 mA∙h/g (1 mol Sb 2 Se 3 -9 mol Na +) [7, 17, 18, 20]. Evidently, the theoretical capacity of antimony selenides is less than that of antimony sulfides and oxides and it is equivalent to that of metal Sb.

Can antimony be commercialized?

Considerations are made in terms of the economics of the material and the fact that it can be commercialized. Pure antimony material, although energy density and power density are not as good as other materials. Its simple synthesis process can bring some economic benefits.

Why is antimony important in sodium ion batteries?

You have full access to this open access article The development of sodium-ion (SIBs) and potassium-ion batteries (PIBs) has increased rapidly because of the abundant resources and cost-effectiveness of Na and K. Antimony (Sb) plays an important role in SIBs and PIBs because of its high theoretical capacity, proper working voltage, and low cost.

What is antimony sulfide (Sb2S3)?

Owing to its high theoretical specific capacity, effective working voltage, and abundant raw materials, antimony sulfide (Sb2S3) was regarded as one promising anode material for electrochemical ene...
