The rejuvenation of spent batteries will not only transform the huge quantity of solid wastes into valuable resources but also promote the sustainable use of natural resources, while mitigating the environmental risks in association with landfills. Despite the significant progress made in the recovery efficiency through various recycling methods, including pyrometallurgy, hydrometallurgy and direct recycling, each of the currently-used methods is not an entirely pollution-free activity. Herein, the concept of “green” approach is proposed to encompass the “3L” criteria, which denotes Less energy consumption, Less greenhouse gas emissions, and Less operational cost. To achieve this great objective, the green potential for various recycling methods is examined in this overview. Additionally, we systematically discuss the optimal approaches for enhancing environmental friendliness while maintaining high recovery efficiency, with particular emphasis on the mild leaching and relithiation processes. Furthermore, in targeting of the main challenges of inadequate scalability, poor battery traceability, and high labor consumption, a multiple closed-loop recycling roadmap that includes regulation, artificial intelligence-assisted pretreatment, targeted recycling and other novel applications, is developed, highlighting the green-sustainable concept for the next-generation battery recycling industry.</p></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"3 ","pages":"Article 100034"},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949881323000343/pdfft?md5=f988438f2f1143e4a3d45693a4e9e785&pid=1-s2.0-S2949881323000343-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138582260","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}

However, we have to address four underlying challenges in energy transition, including (1) to achieve heat electrification, (2) to utilize decommissioned thermal power plants, (3) to meet the demand for large-scale heat storage, and (4) to puzzle out the final “10 ​%” emissions. Given the above challenges, we put forth four heat pump-assisted approaches to break the bottleneck of energy transition and facilitate effective incentive strategies for policymakers.

Although noble metal SACs offer many advantages in CO₂ reduction, their high cost and scarcity have deterred many researchers. Consequently, the focus has shifted toward low-priced transition metals, which have shown better performance than some rare metals. This comprehensive review focuses on the research advances in electrocatalysis for CO₂ reduction reaction using SACs in the past five years. The main synthesis strategies of SACs in recent years are also summarized in detail. Furthermore, based on the difference in the catalytic performance and stability of different catalysts, the review summarizes the performance of non-noble metal SACs (such as Fe, Ni, Co, Mn, Cu, Sn, and Zn) with single metal sites in CO₂ reduction reaction. The discussion of the potential mechanisms is included.

The results showed that the enhancement factor was firstly increased and then decreased with the rising nanoparticle solid content, and the extreme point appeared at 0.6 ​g/L. Based on the experimental data, a relevant empirical formula and a back propagation neural network (BPNN) model were used to estimate the enhancement factor of nanofluid and both exhibited good applicability. Additionally, an optimization model incorporating genetic algorithm, particle swarm algorithm and adaptive learning rate (C-BPNN) was also proposed to estimate the enhancement factor. Compared with the empirical formula and BPNN, C-BPNN exhibited a higher prediction accuracy (all data R² ​= ​0.9966) and a faster prediction rate. The weight analysis of key parameters (nanoparticle solid content, concentration of MEA and MDEA) showed that the relative importance of nanoparticle solid content was foremost (42.63%) in the absorption enhancement process.

Therefore, CO₂ transport and its distribution in porous biofilm are crucial for microalgae decarbonization and its energy utilization. In order to get detailed process information of CO₂ transport and its bioconversion, a mathematical model considering the microalgae growth and its material consumptions was established for substances' flow and transport processes in an immersed microalgae biofilm reactor. Modeling results showed that CO₂ concentration on the surface of biofilm reduced about 26.57% along the flow direction. Increased inlet CO₂ concentration (0.2–5.2 ​mM) significantly promoted the average specific growth rate of biofilm, which was more dramatical at a low flow rate with an enhancement about 7.38 times. Essential reason for it is a synchronous increase on total transfer flux of CO₂ (8.25 times by <span><math><mi>ϕ</mi><msub><mo>_</mo><mrow><mi>C</mi><msub><mi>O</mi><mn>2</mn></msub></mrow></msub></math></span>) and average CO₂ consumption rate (7.48 times by <span><math><mi>A</mi><mi>C</mi><mi>R</mi><msub><mo>_</mo><mrow><mi>C</mi><msub><mi>O</mi><mn>2</mn></msub></mrow></msub></math></span>) in biofilm.
