For glass-ceramics, how to realize the collaborative optimization of BDS and permittivity is the key to improve the energy storage density. In this work, ZrO₂ is introduced into BPKNAS glass-ceramics as nucleating agent to promote crystal development of glass-ceramics and then achieve high permittivity. When 1.5 mol% ZrO₂ is added, the glass-ceramics have the highest permittivity (∼128.59) and meanwhile possess high BDS (1948.90 kV/cm) due to the dense microstructure. Therefore, BPKNAS-1.5ZrO₂ glass-ceramics has the highest theoretical energy storage density (21.62 J/cm³). Moreover, the permittivity variation of BPKNAS-1.5ZrO₂ glass-ceramics is less than 6 % in the wide temperature range from −80 to 300 °C, showing excellent temperature stability. In addition, BPKNAS-1.5ZrO₂ glass-ceramics possesses ultrahigh power density, which reaches up to 382.40 MW/cm³ in overdamped circuit. The above evidence shows that BPKNAS-1.5ZrO₂ glass-ceramics with ultrahigh energy storage density and power density is very competitive in the field of energy storage applications.

对于微晶玻璃，如何实现北斗与介电常数的协同优化是提高储能密度的关键。本工作将ZrO ₂作为成核剂引入BPKNAS微晶玻璃中，促进微晶玻璃的晶体发育，进而实现高介电常数。当添加1.5 mol% ZrO ₂时，微晶玻璃具有最高的介电常数（~128.59），同时由于微结构致密而具有高BDS（1948.90 kV/cm）。因此，BPKNAS-1.5ZrO ₂微晶玻璃具有最高的理论储能密度（21.62 J/cm ³）。此外，BPKNAS-1.5ZrO _{2的介电常数变化}微晶玻璃在 -80 至 300 °C 的宽温度范围内低于 6%，显示出出色的温度稳定性。此外，BPKNAS-1.5ZrO ₂微晶玻璃具有超高的功率密度，在过阻尼电路中可达382.40 MW/cm ³。上述证据表明，具有超高储能密度和功率密度的BPKNAS-1.5ZrO _{2微晶玻璃在储能应用领域具有很强的竞争力。}
