“…From the groundbreaking research of nanowires for reducing the mechanical stress of Si anodes to the polysulfide trapping capabilities of porous carbon with nanosized pores for S cathode, it appears that the spark for many of these initially abandoned chemistries began specifically with nanotechnology. It seems that nanomaterials will play an instrumental role in battery science both practically and academically . Interestingly, the improvement of the commercial Li‐based batteries has not been as spectacular when compared to the volume of literature published regarding nanomaterials and LIBs.…”

Over the past 30 years, significant commercial and academic progress has been made on Li-based battery technologies. From the early Li-metal anode iterations to the current commercial Li-ion batteries (LIBs), the story of the Li-based battery is full of breakthroughs and back tracing steps. This review will discuss the main roles of material science in the development of LIBs. As LIB research progresses and the materials of interest change, different emphases on the different subdisciplines of material science are placed. Early works on LIBs focus more on solid state physics whereas near the end of the 20th century, researchers began to focus more on the morphological aspects (surface coating, porosity, size, and shape) of electrode materials. While it is easy to point out which specific cathode and anode materials are currently good candidates for the next-generation of batteries, it is difficult to explain exactly why those are chosen. In this review, for the reader a complete developmental story of LIB should be clearly drawn, along with an explanation of the reasons responsible for the various technological shifts. The review will end with a statement of caution for the current modern battery research along with a brief discussion on beyond lithium-ion battery chemistries.

In light of the increased emphasis on lightweighting of vehicular components and continued use of high‐performance aluminum alloys in the aerospace industry, designing alternatives to carcinogenic chromium‐based corrosion control systems has emerged as an urgent imperative. The high activity of aluminum and the heterogeneous surface structure of Al alloys renders effective corrosion inhibition a formidable challenge. Here, the effective corrosion protection of AA7075 alloys by Mg/polyetherimide nanocomposite coatings prepared by dispersing solution‐grown Mg nanocrystals within a polyamic acid matrix followed by imidization on the substrate are demonstrated. The active nanocrystal filler and nanocomposite are characterized using powder X‐ray diffraction (XRD), Fourier transform infrared spectroscopy, and cross‐sectional electron microscopy. Electrochemical impedance spectroscopy (EIS) and open circuit potential (OCP) responses of coatings are evaluated over the course of 100 days of exposure to a 3.5 wt% aqueous solution of NaCl. These results suggest that the nanocomposite coatings endow efficacious cathodic and barrier protection to the underlying alloy substrate. The Mg/PEI nanocomposite coatings endow immediate cathodic protection to AA7075 substrates upon salt water immersion with rapid mobilization of the active filler. The nanocomposites represent a vital addition to the sparse set of chrome‐free options for corrosion protection of lightweight alloys.

“…The strong impetus for reducing fuel consumption along with increasingly stringent global emissions standards have spurred a worldwide push towards lightweighting of vehicles. [1][2][3][4][5] Lightweighting of vehicular components is most often targeted through (a) the replacement of steel by magnesium and aluminum alloys, engineered polymers, or carbon fiber composites or (b) through the design of porous monolithic forms (increasingly accessible from additive manufacturing methods) that provide load-bearing capabilities and mechanical resilience comparable to fully dense fabricated parts but with much greater economy of material consumption. 6,7 In contrast to vehicular transportation, the use of light-weight metal alloys is much more prevalent in other sectors where they are designed to meet demanding structural specifications.…”
