Researchers at Colorado State University have developed a novel method for the electrodeposition of pure phase SnSB (tin antimony alloy) forming a high stability lithium-ion battery anode. The novel methods do not require binders or carbon additives, resulting in longer cycle lifetimes.

Energy storage will be of importance for the foreseeable future, with the increased demand for electric vehicles and automakers committed to turning cars into all electric vehicles. Secondary batteries play a major role in energy storage as the world slowly transitions from non-renewable sources, such as fossil fuels, to cleaner and more sustainable storage methods. Currently, graphite is commercially used as the anode for a majority of lithium-ion batteries and saturates the market, although silicon is slowly beginning to push into commercial industries.
Current battery technology can be improved by replacing current graphite anodes because these anodes have low gravimetric capacity that results from only being able to hold one lithium for every six carbon atoms. Alloy materials have been studied as a potential anode replacements for commercial graphite anodes due to their greater volumetric and gravimetric capacities when compared to graphite. Alloy anodes have two to ten times the theoretical gravimetric capacity of graphite due to their ability to react with multiple lithium per metal center.
