数十年续航的核电池Nuclear Batteries That Last For Decades
➀ 研究人员正在开发一种核电池，这种电池可以持续数十年甚至上千年无需充电，为锂离子电池提供了一个有前景的替代方案。
➁ 该技术使用碳-14，这是一种碳的放射性同位素，其发射的贝塔粒子可以通过薄材料安全屏蔽。
➂ 通过采用基于二氧化钛的半导体并用钌基染料敏化，研究人员将能量转换效率显著提高，从0.48%提升至2.86%。
➀ Researchers are developing nuclear batteries that could last for decades or even millennia without recharging, offering a promising alternative to lithium-ion batteries.
➁ The technology uses carbon-14, a radioactive isotope of carbon, which emits beta particles that can be safely shielded with thin materials.
➂ By enhancing the energy conversion efficiency through a titanium dioxide-based semiconductor sensitized with a ruthenium-based dye, the researchers achieved a significant increase in efficiency from 0.48% to 2.86%.
