      abstract     = {To address the issue that a single coating agent cannot
                      simultaneously enhance Li+-ion transport and electronic
                      conductivity of Ni-rich cathode materials with surface
                      modification, in the present study, we first successfully
                      synthesized a LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode material
                      by a Taylor-flow reactor followed by surface coating with
                      Li-BTJ and dispersion of vapor-grown carbon fibers treated
                      with polydopamine (PDA-VGCF) filler in the composite slurry.
                      The Li-BTJ hybrid oligomer coating can suppress side
                      reactions and enhance ionic conductivity, and the PDA-VGCFs
                      filler can increase electronic conductivity. As a result of
                      the synergistic effect of the dual conducting agents, the
                      cells based on the modified NCM811 electrodes deliver
                      superior cycling stability and rate capability, as compared
                      to the bare NCM811 electrode. The CR2032 coin-type cells
                      with the NCM811@Li-BTJ + PDA-VGCF electrode retain a
                      discharge specific capacity of $∼92.2\%$ at 1C after 200
                      cycles between 2.8 and 4.3 V (vs Li/Li+), while bare NCM811
                      retains only $84.0\%.$ Moreover, the NCM811@Li-BTJ +
                      PDA-VGCF electrode-based cells reduced the total heat (Qt)
                      by ca. $7.0\%$ at 35 °C over the bare electrode.
                      Remarkably, the Li-BTJ hybrid oligomer coating on the
                      surface of the NCM811 active particles acts as an artificial
                      cathode electrolyte interphase (ACEI) layer, mitigating
                      irreversible surface phase transformation of the layered
                      NCM811 cathode and facilitating Li+ ion transport.
                      Meanwhile, the fiber-shaped PDA-VGCF filler significantly
                      reduced microcrack propagation during cycling and promoted
                      the electronic conductance of the NCM811-based electrode.
                      Generally, enlightened with the current experimental
                      findings, the concerted ion and electron conductive agents
                      significantly enhanced the Ni-rich cathode-based cell
                      performance, which is a promising strategy to apply to other
                      Ni-rich cathode materials for lithium-ion batteries.},
