Our battery materials are produced through a scalable and economical solid state synthesis process, which is adaptable to different materials compositions and particle morphologies. NEI supplies its Li-ion battery cathode & anode materials as both powders and cast electrode tapes. Our standard tape is cast on 5″ x 10″ aluminum (or copper) foil and coated on one side, with an 80% active material loading but can be customized to accommodate different active material loadings, coating thickness, binder type (aqueous/non-aqueous), and binder content, as well as choice of current collector.
NEI also offers cast electrodes of LCO, NCA, & LMNO that have been coated with an oxide using Atomic Layer Deposition (PICOSHIELD® ALD from PneumatiCoat Technologies). ALD surface coatings, which are only a few nanometers thick, offer a myriad of improved benefits to lithium-ion batteries. These “artificial SEI” layers provide critical protection at the electrode and electrolyte interface, delivering extended lifetime (reduced transition metal dissolution, reduced electrolyte decomposition) and better safety (reduced gassing, overvoltage protection, higher thermal runaway temperature and better abuse tolerance).
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.
NANOMYTE® ALD-BE20E (LiCoO2) is a cast electrode prepared with Lithium Cobalt Oxide that has been coated with an oxide using Atomic Layer Deposition. ALD surface coatings, which are only a few nanometers thick, offer a myriad of improved benefits to lithium-ion batteries.
Lithium manganese oxide (LiMn2O4) is a cathode material with a spinel structure, which allows the material to be discharged at high rates. LMO-based batteries are most suited for use in high rate applications.
Lithium nickel cobalt aluminum oxide (LiNi0.8Co0.15Al0.05O2) is a cathode material that provides higher capacity than LiCoO2 when both are charged to 4.2 / 4.3V. NCA-based batteries are most suited for use in moderate rate applications that require high energy density.
Lithium manganese nickel oxide / spinel (LiMn1.5Ni0.5O4) is a cathode material that can be charged at high voltage (5V). Due to the high potential, the material has a higher energy density compared to lithium cobalt oxide and lithium iron phosphate. LMNO-based batteries can be used in high rate applications.
