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).
Rational design of a high-energy LiNi0.8Co0.15Al0.05O2 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.
