Bendable, flexible and self-supported anode materials with excellent electrochemical properties have highly attractive for the high performance lithium-ion batteries (LIBs).
To improve the plasma ablation resistance of carbon/carbon composites, SiBCN and ZrB 2 fillers were introduced in this study by dipping and winding combined with reactive hot pressing. And SiBCN fillers were obtained by the in situ reaction of C and SiBON at a lower hot pressing temperature to avoid carbon fiber damage caused by the filler at higher temperatures. In addition, flake graphite and carbon black were selected as in situ reaction carbon sources for the synthesis of composites, denoted as C f /CGZ and C f /CBZ, respectively. The results showed that the C f /CGZ composites had higher flexural strength and fracture toughness than C f /CBZ composites by the pull-out of flake graphite. In addition, after being exposed to a plasma flame of 6.68 MW/m 2 for 300 s, the C f /CGZ composite showed better ablation resistance with mass and linear ablation rates of 0.39 mg/s and -0.19 μm/s, respectively, which were 22.00 % and 64.81 % lower than the C f /CBZ composite. This was due to the presence of flake graphite which increased the thermal conductivity of C f /CGZ composites and reduced the surface temperature and temperature gradient during ablation. The surface of C f /CGZ composites formed a dense Zr O 2 /SiO 2 oxide layer and exhibited higher reliability compared to C f /CBZ composites.
