VGCF 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.
Figure 2 shows p as a function of VGCF volume content Up) for the composites at room temperature, p Drops dramatically more than 10 orders of magnitude with increasing [phi] from 3 to 8 vol%.
4, 5, and 7) showed significant aggregation of VGCF
To prepare PI/VGCF
nanocomposite films with different VGCF
concentrations, a desired quantity of the VGCF
was added to NMP.
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
Two types of CNFs used in this work were VGCF
and vapor-grown carbon nanofibers (VGNF) produced by the CCVD method.
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.
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.
Demand for VGCF
is continuing to grow rapidly, mainly for use as additives in lithium-ion batteries.
