HUNTINGDON, UK / AGILITYPR.NEWS / October 06, 2020 / Goodfellow is pleased to announce 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, etc. 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*

LiCoO₂    Lithium Cobalt Oxide                     

As one of the most common oxide cathode materials for traditional Li-ion batteries, LiCoO₂ (LCO) is also under consideration for use in all solid-state batteries.       

LiMn₂O₄       Lithium Manganese Oxide       

The spinel lithium manganese oxide (LiMn₂O₄ or LMO) is an exceptional cathode material for aqueous and organic lithium-ion batteries due to its low cost, environmental friendliness and suitable potential capabilities.

LiNi_0.5Mn_1.5O₄   Lithium Nickel Manganese Oxide (LNMO)              

Lithium nickel manganese oxides are 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*

Li₄Ti₅O₁₂   Lithium Titanium Oxide

LTO (Li₄Ti₅O₁₂) has 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*

Li₇La₃Zr₂O₁₂      Lithium Lanthanum Zirconium Oxide (LLZO)          

Solid-state electrolyte lithium lanthanum zirconium oxide garnet (LLZO) has attracted a great deal of attention due to its high room temperature conductivity of lithium ions and stability against lithium metal electrodes.

Li₄SiO₄   Lithium Orthosilicate                            

This is a solid-state electrolyte for lithium-ion batteries and specifically for the production of solid-state thin film batteries (TFB).
