24.07.2020We developed an effective 2D materials synthesis method: Polymer "tape"-assisted ball-milling method, which very suitable for fabricating low-cost, large-capacity, and high-rate electrodes. Simply, bulk Bi, polyvinylidene fluoride (PVDF) and N-methyl-2-pyrrolidone (NMP) with a mass ratio of 5:10:90 are mixed for ball-milling.

Abstract In this paper, high-purity and fine (W0.2V0.2Ta0.2Nb0.2Ti0.2)B2 (HEB) powders were obtained via a simple high-energy ball milling-assisted boro/carbothermal reduction method at 1600C. Results showed that the heating temperature and B source contents played a key role in the synthesis of purity of single-phase HEB powders.
