“…Several studies have pointed to challenges with PEMFC durability due to degradation in the membrane and catalyst layer during long-term operation [27][28][29] . Battery EVs, on the other hand, generally suffer from limited driving ranges, and whilst larger batteries allow for longer driving ranges, they also cause more production-phase impacts and add weight to the vehicle, thereby increasing electricity consumption during EV operation 30 . As many excellent reviews already cover the contribution of nanomaterials to overcoming technological and commercialization challenges of LIBs and PEMFCs [31][32][33][34][35][36] , this review rather screens the environmental effects arising from the use of nanomaterials in these devices.…”

“…The precipitation method employs heavy chemical usage pre-and post-synthesis for purifying the product and accompanying wastewater generation from centrifugation or other separation techniques 29 . Sol-gel offers control over purity, composition, homogeneity and temperature, but it also requires large amount of organic solvents and reagents 30 and has low yield 29 . Metal organic CVD is a high cost route 30 that has a low precursor utilization efficiency of only 1 to 20% and at least 50% of the precursor gases becomes waste 29 .…”

“…Synthesis material losses were evaluated based on synthesis protocols available in the literature, as well as synthesis reviews describing environmentally significant aspects [27][28][29][30] . Because bottom-up methods allow for the customized design of reactions and processes at the molecular level and thereby minimizing unwanted waste, it is generally believed that top-down techniques are more wasteproducing than bottom-up techniques 29 .…”

Electric vehicles (EVs) powered by lithium ion batteries (LIBs) or proton exchange membrane hydrogen fuel cells (PEMFCs) offer important potential climate change mitigation effects when combined with clean energy sources. The development of novel nanomaterials may bring about the next wave of technical improvements for LIBs and PEMFCs. If the next generation of EVs is to lead to not only reduced emissions during use but also environmentally sustainable production chains, the research on nanomaterials for LIBs and PEMFCs should be guided by a lifecycle perspective. In this Review, we describe an environmental lifecycle screening framework tailored to assess nanomaterials for electromobility. By applying this framework, we offer an early evaluation of the most promising nanomaterials for LIBs and PEMFCs and their potential contributions to the environmental sustainability of EV lifecycles. Potential environmental trade-offs and gaps in nanomaterials research are identified to provide guidance for future nanomaterial developments for electromobility.

Although transition metal oxide electrodes have large lithium storage capacity, they often suffer from low rate capability, poor cycling stability, and unclear additional capacity. In this paper, CoO nanowire clusters (NWCs) composed of ultra-small nanoparticles (≈10 nm) directly grown on copper current collector are fabricated and evaluated as an anode of binder-free lithium-ion batteries, which exhibits an ultra-high capacity and good rate capability. At a rate of 1 C (716 mA g −1 ), a reversible capacity as high as 1516.2 mA h g −1 is obtained, and even when the current density is increased to 5 C, a capacity of 1330.5 mA h g −1 could still be maintained. Importantly, the origins of the additional capacity are investigated in detail, with the results suggesting that pseudocapacitive charge and the higher-oxidation-state products are jointly responsible for the large additional capacity. In addition, nanoreactors for the CoO nanowires are fabricated by coating the CoO nanowires with amorphous silica shells. This hierarchical core-shell CoO@SiO 2 NWC electrode achieves an improved cycling stability without degrading the high capacity and good rate capability compared to the uncoated CoO NWCs electrode.

Exploring Critical Factors Affecting Strain Distribution in 1D Silicon‐Based Nanostructures for Lithium‐Ion Battery Anodes

et al. 2018

Despite the advantage of high capacity, the practical use of the silicon anode is still hindered by large volume expansion during the severe pulverization lithiation process, which results in electrical contact loss and rapid capacity fading. Here, a combined electrochemical and computational study on the factor for accommodating volume expansion of silicon-based anodes is shown. 1D silicon-based nanostructures with different internal spaces to explore the effect of spatial ratio of voids and their distribution degree inside the fibers on structural stability are designed. Notably, lotus-root-type silicon nanowires with locally distributed void spaces can improve capacity retention and structural integrity with minimum silicon pulverization during lithium insertion and extraction. The findings of this study indicate that the distribution of buffer spaces, electrochemical surface area, as well as Li diffusion property significantly influence cycle performance and rate capability of the battery, which can be extended to other silicon-based anodes to overcome large volume expansion.
