Накратко на български

Натриево-йонните батерии с аноди от биоотпадъци се анализират чрез рентгенови техники, за да се види как се образува защитният слой (SEI) върху тях в реално време. Това помага за създаването на по-евтини и устойчиви алтернативи на литиево-йонните батерии за съхранение на енергия.

opeRando chEmical spAce- and time-resoLved quantification of Solid Electrolyte Interphase in hard carbon anode for sustainable sodium-ion batteries

Problem/Issue Being Addressed: REALSEI aims to pioneer real-time visualization of the Solid Electrolyte Interphase (SEI) formation on hard carbon anodes in sodium-ion batteries, a process largely unexplored at the local electrochemical level. Importance for Society: The urgency of our work is evident in the need to limit global warming to 2.7°C by 2100, requiring a tripling of global grid energy storage capacity by 2050. A transformative breakthrough is imperative, and that lies in the development of a low-cost, sustainable alternative to lithium-ion batteries. The 'Beyond-Lithium' batteries, specifically sodium-ion-based systems, hold immense promise. Bio-waste mesoporous hard carbon (BHC) emerges as a leading candidate—an abundant, low-cost, and recyclable anode material. BHC's adoption in beyond-lithium batteries could usher in the next generation of sustainable energy storage solutions. Overall Objectives: REALSEI's primary mission is to establish a comprehensive operando time- and space-resolved characterization methodology. This transition from bulk to surface analytical characterization relies on high-resolution X-ray techniques, both lab-based and synchrotron-based. The ultimate goal is the real-time visualization and quantification of SEI species on hard carbon. The project unfolds in three main objectives: • O1: Optimization of HC materials synthesis and characterization. • O2: Evaluation of HC electrode performance in sodium-ion batteries. • O3: Visualization of operando SEI growth using High Resolution X-ray Spectrometry and protocol validation. These objectives have been successfully met within the project timeline.

Цел на проекта

The goal of REALSEI is to visualize for the first time in real-time the Solid Electrolyte Interphase formation at the hard-carbon (HC) anode in a Na-ion battery (NIB). Local electrochemical processes occurring at the solid-liquid interface of Na-ion batteries are currently largely unexplored. To keep global warming around 2.7°C by 2100, the installed global grid energy storage capacity needs to be tripled by 2050. A technological breakthrough is required to meet this challenge: we need a low cost and sustainable alternative to Li-ion batteries. Thanks to recent advances, the so-called ‘beyond-lithium’ batteries (BLB) such as K+ and Na+ based systems could be an everyday reality. Bio-waste mesoporous hard carbon (BHC) is one of the most promising anode materials as a universal ion host for BLBs. The use of BHC as a low-cost and recycled solution in BLBs might provide the breakthrough required and give rise to the next generation of batteries. However, uncontrolled SEI formation limits the large-scale application of BHC in BLBs, in particular for Na-ion batteries (NIBs), the most mature and promising. For NIBs, the SEI is still an unresolved issue that limits its long-term stability. REALSEI wants to establish a comprehensive operando time- and space- resolved characterization methodology to transit from bulk (transmission mode) to surface analytical characterization (grazing incidence mode) based on lab and synchrotron high-resolution X-ray techniques which will results for the first time in a comprehensive visualization and quantification of the species forming the SEI in real-time on HC. REALSEI will apply principles of physics and electrochemistry and its results will have substantial scientific, technological, and societal impact.
