6 new products for use in Li-ion batteries

Goodfellow is has just 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, 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.

LiNi0.5Mn1.5O4: Lithium Nickel Manganese Oxide (LNMO)
Lithium nickel manganese oxides are promising because they are nontoxic while having high thermal stability. They are currently attracting attention as alternative cathode electrode materials to the commercial LiCoO2 electrode.

Anode materials*

Li4Ti5O12: Lithium Titanium Oxide
LTO (Li4Ti5O12) has been highlighted as an 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).

Other products available from Goodfellow that can be used in lithium batteries

Li3PO4: Lithium Phosphate
This thin-film solid electrolyte material known as LiPON is used in thin-film lithium batteries (TFB).

Copper foils (as current collectors), nickel foils, cobalt foils, aluminum foils (battery slurry).

Graphite: For negative electrodes.

Silicone elastomer in any form.

PVDF films: Used as binders, depending on the battery.

*Available as sputtering targets, or in powder form upon request.
