A battery of options

Goodfellow recently announced the addition of six chemical compounds for use in Li-ion batteries. Each of these materials offers something different in terms of the variables associated with Li-ion batteries, such as energy density, potential safety, cost, recharging time, cycle life, scalability and so on. Customers are encouraged to contact a member of the Goodfellow technical team to discuss specific application requirements.
A lithium-ion battery consists of a cathode (positive electrode), an anode (negative electrode), and an electrolyte (used as a conductor) with a charge-discharge cycle.
Cathode materials include Lithium Cobalt Oxide (LiCoO2), one of the most common oxide cathode materials for traditional Li-ion batteries, it is also under consideration for use in all solid-state batteries.
Lithium Manganese Oxide (LiMn2O4), this spinel lithium manganese oxide is an exceptional cathode material for aqueous and organic lithium-ion batteries due to its low cost, environmental friendliness and suitable potential capabilities.
Lithium Nickel Manganese Oxide (LiNi0.5Mn1.5O4) looks promising, being nontoxic while having high thermal stability. They currently are attracting attention as alternative cathode electrode materials to the commercial LiCoO2 electrode.
Anode materials such as Lithium Titanium Oxide (Li4Ti5O12) have been highlighted as anode material for next-generation lithium-ion secondary batteries due to advantages such as a high rate capability, excellent cyclic performance, and safety.
Solid electrolytes include Lithium Lanthanum Zirconium Oxide (Li7La3Zr2O12) that has attracted a great deal of attention due to its high room temperature conductivity of lithium ions and stability against lithium metal electrodes. While Lithium Orthosilicate (Li4SiO4) is a solid-state electrolyte for lithium-ion batteries and specifically for the production of solid-state thin film batteries (TFB).
For more than 50 years, Goodfellow has been a leading supplier of metals, polymers, ceramics and other materials to meet the needs of science and industry worldwide. The company specialises in supplying small quantities (a few grams to a few kilos) of metals and materials for research, prototype development and specialised manufacturing applications. Standard products can be found online at the comprehensive Goodfellow Catalogue. Custom products and materials in larger quantities are available upon request.
