Tohoku University Technology: Oxide ceramics – carbon composite and its manufacturing process: T15-104
Manufacturing Li4Ti5O12-carbon composite by using microwave at low cost!
Ceramics – carbon composite having multi-function is developed in the recent years. However, the composite is heated at high temperature for a long time during the manufacturing process so the particles are sintering between them and the Li4Ti5O12 nano particles able to generate high power cannot be obtained. Moreover, the synthesis method is complex and uses expensive raw materials so the manufacturing cost is high. This invention can provide oxide ceramics – carbon composite and its manufacturing process with reduced cost. This invention manufacturing process is to mix raw material of oxide ceramics made by LiO2 and TiO2 with carbon and fire with microwave in order to create Li4Ti5O12 carbon composite. As result, Li4Ti5O12 crystalline particle which is an oxide ceramics having particle diameter lower than 250nm; and oxide ceramics – carbon composite having above mentionned carbon bond on the crystal plane (111) and (200) of the oxide ceramics – carbon composite were obtained.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
