Lithium Titanate (LTO) Tapes

Anode Electrode Sheets

Lithium Titanate / lithium titanium oxide (Li4Ti5O12, also referred to as LTO) is an electrode material with exceptional electrochemical stability. It is 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 rate.

NEI’s NANOMYTE® BE-10E is a cast electrode tape of our ultrafine LTO and BE-10CE is a cast electrode tape of our carbon-coated LTO, capable of high rates. Standard electrode sheets are 5 inches x 10 inches (127 mm x 254 mm) and cast either single-sided or double-sided on 10 µm thick copper foil current collectors. NEI also offers custom tailored solutions for customers with unique specification requirements. Our tapes can also 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.

Both of our LTO materials are also available in powder form.
