The discovery of lithium-selenium (Li2Se) dates back to the early 1970s, when researchers at the University of California, Berkeley, first synthesized the compound. Since then, Li2Se has been studied extensively for its potential use in batteries, fuel cells, and other energy storage devices.
Typical Use #
Li2Se is a promising material for use in rechargeable batteries, due to its high energy density and low cost. It is also used in fuel cells, where it can be used to store and release energy. Li2Se has been used in a variety of applications, including electric vehicles, portable electronics, and energy storage systems.
Li2Se is typically designed as a solid-state material, with a layered structure consisting of alternating layers of lithium and selenium. This layered structure allows for efficient charge transfer between the two elements, resulting in a high energy density. Li2Se can also be designed as a liquid-state material, with a solution of lithium and selenium in a solvent. This liquid-state design has the advantage of allowing for easier manufacturing and more efficient charge transfer.
Li2Se has a high energy density, with a theoretical capacity of up to 1,000 mAh/g. It also has a high power density, with a maximum discharge rate of up to 10C. Li2Se is also relatively stable, with a low self-discharge rate and a long cycle life.
Li2Se is a relatively safe material, with no known toxicity or environmental hazards. However, it is important to note that Li2Se is highly reactive, and must be handled with care. It is also important to note that Li2Se is flammable, and should be stored and handled in a safe manner.
Li2Se can be manufactured using a variety of methods, including electrochemical deposition, chemical vapor deposition, and sputtering. These methods allow for the production of Li2Se in a variety of shapes and sizes, making it suitable for a wide range of applications.
Li2Se is relatively inexpensive, with a cost of around $2-$3 per gram. This makes it an attractive option for many applications, particularly those that require high energy density and low cost.
