Anode Materials for Lithium-ion Batteries

Anode materials are the negative electrode in lithium-ion batteries and are paired with cathode materials in a lithium-ion cell. The anode materials in lithium-ion cells act as the host where they reversibly allow lithium-ion intercalation / deintercallation during charge / discharge cycles. General criteria for selection of suitable intercalation-based anode materials include (i) low first cycle irreversible loss, (ii) high coulombic efficiency, (iii) fast lithium-ion diffusion into and out of the anode, (iv) high ionic and electronic conductivity, (v) minimum structural changes upon charge and discharge, (vi) high specific capacity (mAh/g), and (vii) the ability to form and maintain a stable SEI (Solid Electrolyte Interface) layer upon cycling.

NEI’s anode materials are available for purchase as both powders and cast electrode tapes. In addition to our standard anode materials below, NEI can also custom produce anode materials based on your requirements.

NANOMYTE® Anode Powders

Our battery materials are produced through a scalable and economical solid state synthesis process, which is adaptable to different materials compositions and particle morphologies. In addition to supplying the standard cathode compositions listed below, we can custom produce any lithium battery material composition of your choice – oxide, sulfide, and carbon coated.

Lithium Titanium Oxide (LTO) powder »

Lithium titanate (Li4Ti5O12) is an electrode material with exceptional electrochemical stability, often used as the anode in lithium-ion batteries for applications that require high rate, long cycle life, and high efficiency. LTO-based batteries are considered safer and have a wider operating temperature range.

Custom Anode Materials »

NEI specializes in developing new compositions and particle morphologies (including nanoscale particle engineering) and has been a long trusted source for customized cathode and anode materials used in lithium-ion batteries.

NANOMYTE® Anode Electrode Sheets

NEI’s standard electrode sheets are offered in economical, ready-to-ship packages of 2, 5, and 10 sheets (per material). Our standard anode tapes are cast on 5 inch x 10 inch sheets of copper foil, single-side coated with a 90% active material loading (~2 mAh/cm2 capacity). For an additional fee, NEI can also customize tape specifications to accommodate different active material loadings, coating thickness, binder type (aqueous/non-aqueous), and binder content, as well as choice of current collector. If ordered with a cathode, loading will be matched with an anode/cathode capacity ratio of 1.2 (unless specified otherwise). Request your quote today!
