Title:
Life cycle assessment of lithium-based batteries: Review of sustainability dimensions
Lithium-based batteries are essential because of their increasing importance across several industries, particularly when it comes to electric vehicles and renewable energy storage. Sustainable batteries throughout their entire life cycle represent a key enabling technology for the zero pollution objectives of the European Green Deal. The EU’s (European Union) new regulatory framework for batteries is setting sustainability requirements along the whole battery, including value chains. For a comprehensive assessment of battery technologies, it is necessary to include a life cycle thinking approach into consideration from the beginning. This review offers a comprehensive study of Environmental Life Cycle Assessment (E-LCA), Life Cycle Costing (LCC), Social Life Cycle Assessment (S-LCA), and Life Cycle Sustainability Assessment (LCSA) methodologies in the context of lithium-based batteries. Notably, the study distinguishes itself by integrating not only environmental considerations but also social and economic dimensions, encapsulating the holistic concept of sustainability. Challenges unique to each assessment method are outlined, including data availability (with 35 % of the reviewed studies having openly accessible inventory data), methodological inconsistencies, uncertainty around future costs and social impacts. Difficulties such as data uncertainty, challenges in cost comparison, and the lack of standardized measures are underscored. The research identifies critical future directions for LCA, including the need for better data quality, adaptation to new technologies, and alignment with Sustainable Development Goals (SDGs). Future research directions are suggested -including the standardization of methodologies, and fostering interdisciplinary collaboration. Overcoming these challenges holds the potential to advance sustainable practices in the battery industry and contribute to a cleaner energy future. |

Title:
Composite materials for supercapacitor electrodes utilizing polypyrrole nanotubes, reduced graphene oxides and metal–organic framework
Polypyrrole (PPy) is favoured in energy storage for its high pseudo-capacitive performance, notably as poly-pyrrole nanotubes (PPyNTs) due to their easy synthesis, cost-effectiveness and electrochemical solid properties. Metal–organic frameworks (MOFs) have also gained attention for enhancing supercapacitors (SCs). In this study, we fabricated aerogel composites with PPyNTs, MOFs and reduced graphene oxide (rGO) as SC electrode materials. Varying concentrations of PPyNTs and rGO were explored, with MOFs added to assess their impact. Electrochemical tests revealed that the composite with PPyNTs and Zn-MOF achieved the highest specific capa-citance of approximately 270 F/g at 0.5 A/g. |

Title:
Insight into the Li-Storage Property of Surface-Modified Ti2Nb10O29 Anode Material for High-Rate Application
Ti-based anode materials are considered to be an alternative to graphite anodes to accomplish high-rate application requirements. Ti2Nb10O29 (TNO15) has attracted much attention due to its high lithium storage capacity through the utilization of multiple redox couples and a suitable operating voltage window of 1.0 to 2.0 V vs Li/Li+. However, poor intrinsic electronic conductivity has limited the futuristic applicability of this material to the battery anode. In this work, we report the modification of TNO15 by introducing oxygen vacancies and using few-layered carbon and copper coatings on the surface to improve its Li+ storage property. With the support of the galvanostatic intermittent titration technique (GITT), we found that the diffusion coefficient of carbon/copper coated TNO15 is 2 orders of magnitude higher than that of the uncoated sample. Here, highly conductive copper metal on the surface of the carbon-coated oxygen-vacancy-incorporated TNO15 increases the overall electronic and ionic conductivity. The prepared TNO15-800-C-Cu-700 half-cell shows a significant rate capability of 92% when there is a 10-fold increase in the current density. In addition, the interconnected TNO15 nanoparticles create a porous microsphere structure, which enables better Li-ion transportation during charge/discharge process, and experiences an enhancement after the carbon and copper coating on the surface of the primary TNO15 nanocrystallites. |

Title:
Vacuum-Filtered MXene/Carbon Nanotube Composite Films for Li-Ion Capacitors
MXene has garnered significant attention for its applications in electrochemical energy storage devices, such as supercapacitors and Li-ion capacitors, owing to its high electrical conductivity and relatively high capacitance/capacity in both aqueous and organic electrolytes. Utilizing its two-dimensional (2D) structure, this study prepared vacuum-filtered MXene/carbon nanotube (MXene/CNT) composite films for Li-ion capacitors. The incorporation of CNTs plays a critical role in mitigating the restacking of MXene flakes and enhancing the structural integrity of the films. The MXene/CNT films were first characterized by using various physicochemical methods and evaluated in electrochemical half-cells. A Li-ion capacitor was subsequently fabricated by using the MXene/CNT-12% film as the negative electrode and mesoporous carbon as the positive electrode. The fabricated Li-ion capacitor demonstrates a specific capacitance of 26 F g–1, an energy density of 40.2 Wh kg–1, and a power density of 375 W kg–1 at a current density of 0.5 A g–1. However, the electrochemical performance of the device is still limited by the layer-by-layer architecture of the MXene-based films, which hinders the efficient transport of electrolyte ions vertically through the layers. |
