■ Potential for new Cl-cHBC LTO materials
Overview
The existing LTO anode material is suitable for cases where fast charging is required,
such as electric buses, but it has a disadvantage in that the capacity is half as small as
that of graphite, the voltage is low, and the price is high.
The organic cathode material Cl-cHBC, developed by the UNIST-KIST joint research team,
is introduced as being 1.5 times larger in capacity than the LTO material, but is also
cheaper and lighter. The research confirmed the possibility of boosting the performance
of the LFP battery.
"The developed material can be synthesized at low temperatures, so if commercialized,
it will be able to secure additional price competitiveness," the joint research team said.
"Because of its light and high output characteristics, it is expected to be applied not
only in electric vehicles but also in drones."
In this column, we will look at the technology potential of LTO materials through
this paper.
