Case Study

Ultrafine Zirconium Boride Nanoparticles for Lithium-Sulfur Batteries

Wang B, et al. Energy Storage Materials, 2022, 45, 130-141.

Highly conductive ultrafine zirconium boride (ZrB2) nanoparticles can be obtained via solid phase synthesis and further used as sulfur host materials. The ZrB2/Nitrogen-doped graphene/S (ZrB2/NG/S) cathode demonstrates stable performance for 135 cycles at an ultrahigh rate of 20 C, delivering a capacity of approximately 400 mAh g-1. Besides, the ZrB2/NG/S cathode exhibits an extended cycling performance with a minimal decay rate of 0.02% per cycle over 4000 cycles at 5 C.
Preparation procedures of sulfur electrodes
· The ZrB2 was first mixed with NG in a 1:1 mass ratio in ethylene glycol and sonicated for 1 hour. The mixed solution was then transferred into a Teflon-lined stainless steel autoclave and kept at 160 °C for 12 hours. The composite materials were mixed with sulfur in a 3:7 mass ratio and ground in a mortar for 1 hour, then heated at 155 °C for 12 hours to obtain the sulfur composites.
· For the sulfur electrode, the sulfur composite was mixed with ketjen black and LA-133 in an 8:1:1 mass ratio in deionized water to form a slurry. The slurry was then coated on Al foil and dried at 60 °C for 12 hours. The electrode was punched into 10 mm pieces with a sulfur mass loading of around 1 mg cm-2.
· The coin cells were assembled with the sulfur electrode as the cathode, Celgard 2500 membranes as the separator, and 1 M LiTFSI in DOL/DME with 2 wt% LiNO3 as the electrolyte in a glove box filled with argon.

Zirconium Diboride Reinforced Aluminum Matrix Composites

Mohanavel V, et al. Materials Today: Proceedings, 2020, 21, 862-864.

Zirconium diboride (ZrB2) particle reinforced aluminum matrix composites have been widely studied. Studies have shown that the mechanical and tribological properties of the composites are enhanced after the dispersion of ZrB2 particles. In addition, ZrB2 particle matrix composites are mainly manufactured by in-situ casting methods.
Examples of ZrB2 reinforced aluminum matrix composite (AMC)
· Naveen Kumar et al. utilized a direct melt reaction process to prepare AA6351/ZrB2 AMCs and found that the wear resistance increased with a higher weight percentage of ZrB2 particles, leading to a decrease in wear rate.
· Tian et al. investigated the effect of different volume fractions of ZrB2 particles on AA2024 composites and determined that the composites with 5.4% ZrB2 content exhibited superior mechanical properties.
· Dinaharan et al. noticed the microstructural characterization of both the AA6061 unreinforced matrix alloy and its AA6061/ZrB2 composites. The dendrite arm space minimizes when the weight percentage of the particles increases in AA6061/ZrB2 AMCs.
· Mohanavel et al. studied the mechanical behavior of AA2014 and AA6063 composites with ZrB2 reinforcement, finding that the hardness and tensile strength improved as the weight fraction of ZrB2 increased. In both cases, the ZrB2 particles were evenly distributed throughout the aluminum matrix, enhancing the overall properties of the composites.
