Li doping is an effective route to promote such LGG process of Cu2ZnSn(S,Se)4 (CZTSSe) as it can provide liquid Li-Se phase facilitating the growth of large-grain CZTSSe. However, the detailed function of the added Li in grain growth has rarely been investigated in both CZTS and CZTSSe, as the reported in situ, and pre-deposition doping strategies usually suffer from substantial Li losses during the spin-coating process and/or the high-temperature sulfurization process. Herein, by monitoring the temperature-dependent Li loss during the sulfurization process, we demonstrate that a small proportion of the added Li can remain at the CZTS film from the early sulfurization stage and provide Li-S flux to promote the LGG process. An encouraging efficiency of 10.53%, with a remarkably high short-circuit current density of 22.6 mA/cm2 and open-circuit voltage of 0.744 V, is achieved by a significantly enlarged grain size of 3 μm with Li addition. This work could enhance the knowledge of employing Li-S as flux for growing large-grain chalcogenide absorbers for high performance devices with better carrier transport.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.31","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140310308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing novel anode materials with high specific capacities is one of the most effective ways to increase the energy density of LiBs. Herein, a series of Cu and Co binary-transition metal glycerolates (labeled as CuxCoy/G) were prepared as the anodes for LiBs. It was observed that CuxCoy/G exhibited a distinctive yolk-shell architecture, which significantly differed from the solid spherical structure of Cu/G and Co/G counterparts. X-ray powder diffraction and Scanning electron microscope studies suggested that Cu element existed as Cu2+1O in CuxCoy/G, and the Co element was in the form of amorphous glycerolates. Electrochemical studies showed that Cu0.4Co1/G delivered a high capacity over 1000 mAh g−1 at the first discharge, and it exhibited the most stable cycling performance over 200 cycles. Mechanism study suggested both Cu and Co elements contributed to lithium storage capacities in CuxCoy/G at the initial discharging process. Experimental results revealed that Co exhibited reversible capacity while Cu element was reduced to metallic Cu which contributed to the electronic conductivity, rendering Cu0.4Co1/G exhibited a better long-term cycling stability than Co/G. This work explored a new type of anode material with high specific capacity for LiBs, paving the way to high energy density LiBs.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.30","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140250599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among several SSEs, Li7La3Zr2O12 (LLZO) has attracted attention due to its high Li+ ion conductivity (∼10−3 S cm−1 at room temperature for Ga-doped LLZO) and good stability in ambient air. However, the challenges of Li penetration and the chemical instability against Li are the primary obstacles to its practical application. This study investigates the effects of the grain size and electronic conductivity of Ga-doped LLZO on the critical current density (CCD). Using samples with similar interfacial impedances between Ga-doped LLZO and Li, we demonstrate that a decrease in the grain size of Ga-doped LLZO lowers the electronic conductivity, leading to a higher CCD. Furthermore, although a previous study suggests that Ga-doped LLZO might be unsuitable for direct contact with Li, the chemical stability against Li is enhanced in a more compact pellet prepared at a higher cold-pressing pressure. These results underscore the significance of the sintering conditions and pellet pressing pressure in the synthesis of Ga-doped LLZO since they ultimately affect the electrochemical and chemical stabilities of the Ga-doped LLZO solid electrolyte with a Li-metal anode.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.24","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139777946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of CO2RR studies are focused on pure CO2 as feed, while in real CO2 waste streams, such as flue gas or biogas, CO2 concentration does not exceed 40%. Therefore, the economic feasibility of CO2RR and its carbon footprint are greatly limited by the CO2 purification steps before electrolysis ($70–100 per ton of CO2 for CO2/N2 separation). In recent years, studies have exhibited the importance of this matter by integrating CO2 capture and electroreduction in a single unit. Mostly, CO2 capture solutions as electrolytes have been under attention, and promising results have been achieved to significantly improve the overall economy of CO2RR. The focus on CO2 capture-electroreduction integration can go beyond the solution/electrolyte-based CO2 capture (e.g., amine solutions and ionic liquids) and other processes such as solid adsorption and membrane-based processes, as more efficient options, can be potentially integrated with CO2 electroreduction in the gas-diffusion electrode design.
