Investigation of electrolytic tin-nickel alloys as anode materials for lithium-ion batteries

Abstract

Electrolytic deposits of tin-nickel alloys as anodes for lithium ion batteries were investigated by potentiodynamic and galvanostatic cycling methods in solutions of ethylene carbonate, dimethyl carbonate, and LiClO 4 (1 mol/L). It has been shown that the deposits of tin-nickel alloys obtained from alkaline tar trate-trilonate electrolytes in the first cycles are characterized by a high specific capacity of up to 700 mA h/g, which decreases to 500 mA h/g during the cycling. The tin-nickel alloys obtained are able to ensure high charge-discharge current densities without mechanical destruction.

Functional electrolytic coatings of tin-nickel alloys for integrated circuits

“…One of the simplest, well controllable, and most efficient methods for obtaining coatings of alloys such as tin-nickel alloys, is electrodeposition from aqueous solutions of complex compounds [1,2]. This is due to a number of advantages, which are inherent to electrolytes based on metal complexes.…”

“…In modern electroplating technology, polyligand electrolytes [1] such as ammonium-fluoride, citrate, tartrate-trilonate and pyrophosphate-tartrate-glucinate electrolytes, are widely used to deposit tin-nickel alloys. The combination of properly chosen ligands for polyligand electrolytes allows controlling the rate of the electrode process, or stages of it, and hence the structure and properties of the deposited coatings [2,3].…”
