and PS matrix with 2 wt% antioxidant were mixed in a Hakke miniaturized internal mixer rheomix 600 at a roll speed of 60 rpm for 12 min at 190 C.
SDK has therefore decided to increase its production capacities for SCMG and VGCF
, which contribute toward increasing the capacity and extending the life of LIBs.

SDK has succeeded in the development of SCMG on the strength of its lithium-ion battery evaluation technology developed jointly with customers through R&D of VGCF
. Also, SDK's proprietary high-temperature graphitizing technology, accumulated over many years in the graphite electrode business, has contributed to the success.
To prepare PI/VGCF nanocomposite films with different VGCF
concentrations, a desired quantity of the VGCF
was added to NMP.
Two types of CNFs used in this work were VGCF
and vapor-grown carbon nanofibers (VGNF) produced by the CCVD method.
In the second half of the year, the Company started expanding its production capacity of VGCF
vapor-grown carbon nanofiber, which is used as additives in lithium-ion batteries.
The best reinforcing effect is obtained with xGnP-1 that increases the modulus ~900% at a loading of 20 vol% followed by carbon black (at low loadings), PAN-based carbon fibers, VGCF
and xGnP-15 and the nanoclay.
Demand for VGCF
carbon nanofiber is increasing for use in lithium-ion batteries (LIBs) for PCs.
The entanglements of the VGCF
bundle open up and the nanofibers are wetted by the matrix.
Demand for VGCF
is continuing to grow rapidly, mainly for use as additives in lithium-ion batteries.
In past, researchers have used VGCF
with epoxy matrices to improve the electrical and mechanical properties of the composites [35,36].
