Abstract

High-quality Li4Ti5O12/N-doped carbon (LTO/N-C) nanotube arrays on a conductive substrate are fabricated via a new ALD-assisted method for lithium ion battery applications. The designed LTO/N-C nanotube arrays show very impressive high-rate capacity (153 mA h g−1 at 5C) and stable capacity: 98% retention after 6000 cycles at 40C.
