Silicon Single Walled Carbon Nanotube-Embedded Pitch-Based Carbon Spheres Prepared by a Spray Process with Modified Antisolvent Precipitation for Lithium Ion Batteries
The pitch-derived soft carbon and SWCNTs provided an excellent conductivity, and the porous structure of the composite accommodated the stress produced by the Si expansion.
High areal capacity battery electrodes enabled by segregated nanotube networks
High thickness and specific capacity leads to areal capacities of up to 45 and 30 mAh cm−2 for anodes and cathodes, respectively. Combining optimized composite anodes and cathodes yields full cells with state-of-the-art areal capacities (29 mAh cm−2) and specific/volumetric energies (480 Wh kg−1 and 1,600 Wh l−1).
Optimization of Graphite–SiO blend electrodes for lithium-ion batteries: Stable cycling enabled by single-walled carbon nanotube conductive additive
The use of SWCNT conductive additive enables graphite-free SiO electrodes with 74% higher volumetric energy and superior full-cell cycling compared to graphite electrodes.
Rational design of a high-energy NCA cathode for Li-ion batteries
Replacing Denka black with SWCNT allows to reduce the carbon content to 0.2 wt% to further increase the energy density, and 2 wt% of PVDF was shown to benefit the cycling stability due to the mitigated PVDF-induced side reactions from its direct contact with NCA particles.
