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.}, cin = {IEK-12}, ddc = {600}, cid = {I:(DE-Juel1)IEK-12-20141217}, pnm = {1221 - Fundamentals and Materials (POF4-122) / LiBEST2 - Lithium-Batterie-Konzepte mit hoher Energiedichte, Leistung und Sicherheit (13XP0304A)}, pid = {G:(DE-HGF)POF4-1221 / G:(BMBF)13XP0304A}, typ = {PUB:(DE-HGF)16}, pubmed = {38606845}, UT = {WOS:001203989600001}, doi = {10.1021/acsami.3c19386}, url = {https://juser.fz-juelich.de/record/1025926}, }
