概括

离子电池具有储能潜力,但对环境的影响评估至关重要. 这项研究提供了现实数据,显示基于普鲁士白 (PW) 的SIB对环境的影响低于基于酸 (NVP/C) 的SIB.

科学领域:

材料科学
电化学
环境科学

背景情况:

离子电池 (SIB) 是用于大规模储能的离子电池 (LIB) 的一个有希望的替代品.
有限的生命周期评估 (LCA) 研究存在于SIB,通常依赖于理论数据.
环境热点的确定对于可持续的SIB发展至关重要.

研究的目的:

对两个新兴的SIB技术进行比较生命周期评估 (LCA).
分析酸 (NVP/C) 和普鲁士白色 (PW) 阴极活性材料 (CAM) 对环境的影响.
提供SIB环境影响分析的主要实验室数据.

主要方法:

基于初级实验室数据进行生命周期比较评估 (LCA).
专注于NVP/C和PW阴极活性材料的合成.
与基于商业NMC的LIB进行比较.

主要成果:

与基于PW的SIB相比,基于NVP/C的SIB对所有类别的环境影响显著更大.
较低的重力密度和更高的CAM合成影响导致NVP/C的足迹更大.
基于NMC的LIB的环境影响低于SIB技术,因为其能量密度更高.

结论:

与NVP/C相比,普鲁士白 (PW) 成为SIB更有利于环境的阴极材料.
进一步的研究应该集中在提高SIB组件的能量密度和合成过程,以减少环境负担.
由于能源密度较高,LIB目前仍然比SIB具有环境优势.

Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
