Crafting Safe, Long-Cyclable Lithium Metal Batteries for High TemperaturesTBMG-5213912/01/2024
Existing commercial battery technologies, which use liquid electrolytes and carbonaceous anodes, have certain drawbacks such as safety concerns, limited lifespan, and inadequate power density particularly at high temperatures. This has prompted researchers to search for solid electrolytes that are safe and compatible with lithium metal anodes, which are known for their high theoretical specific power capacity.

Effect of Busbar Design on the Thermal Performance of Battery Packs2024-26-013501/16/2024
Li-ion batteries face challenges which is not usually present with other chemistries is cell balancing. If a high imbalance occurs within a parallel circuit, possibly because of the poor cell -grading or due to temperature localization, the other cells will charge the unbalanced cell and it may be possible that the imbalance never completely fades away and the other cells also end up unbalanced, One of the key solutions to maintaining cell balance is to ensure that all cells within a battery pack are kept at a uniform temperature. This requires careful thermal management, which can be achieved through a combination of conduction and convection circuits. In this paper, a 1D-3D simulation study has been performed on a 12 V 4s4p pack by varying the thickness of HV busbars and temperature localization effects and temperature uniformity has been observed. The holder has 16 cells with a 4*4 grid pattern, each cell has a diameter of 18 mm and a length of 65mm. The cells are connected in

SAE TOMORROW TODAY: Autonomous Mining Critical to Global Demand for Minerals1337112/12/2022
With the exponential rise in EV adoption comes a surge in global demand for minerals like graphite, lithium, nickel and cobalt. To keep pace, more mines around the world are needed to get up and running quickly. Enter SafeAI, a company accelerating the world's transition to autonomous mining and construction. By retrofitting heavy duty vehicles and site operations with autonomous technology, SafeAI enables safer, more productive, and more cost-efficient worksites. In terms of supporting the EV supply chain, SafeAI's autonomously operating assets can significantly expedite the development of a mine, which typically takes up to 10 years. Enabled by autonomy, each vehicle can add approximately 1,000 additional hours of productivity per year. We sat down with Bibhrajit Halder, Founder & CEO of SafeAI, to discuss the global state of mining, the move to zero-emission vehicles, and the future of autonomous mining and construction in an era of massive industry adoption.

Product Analysis - Permissible Variations from Specified Chemical Analysis of a Heat or Cast of SteelJ409_202107 (Current)07/15/2021
Supplementary to the heat or cast analysis, a product analysis may be made on steel in the semifinished or finished form. For definitions and methods of sampling steel for product chemical analysis, refer to SAE J408. A product analysis is a chemical analysis of the semifinished or finished steel to determine conformance to the specification requirements. The range of the specified chemical composition is normally expanded to take into account deviations associated with analytical reproducibility and the heterogeneity of the steel. Individual determinations may vary from the specified heat or cast analysis ranges or limits to the extent shown in Tables 1 through 5. The several determinations of any element in a heat or cast may not vary both above and below the specified range except for lead. Tables 1 through 5 provide permissible limits for various steel forms and composition types. For rephosphorized and resulfurized steels, the product analysis tolerance limits are not applicable

Lithium Metal Battery Allows Cold ChargingTBMG-3836301/01/2021
Lithium metal batteries are the next generation of battery after the lithium-ion battery. They use a lithium anode and have higher energy density but have problems with dendritic growth, low efficiency, and low cycle life. To solve these problems, researchers developed a self-assembling monolayer that is electrochemically active so that it can decompose into its proper components and protect the surface of the lithium anode.

Coating Extends Lithium Metal Battery LifeTBMG-3638204/01/2020
The rechargeable lithium metal battery has been plagued by short life expectancy and occasional fires. To combat these problems, a new coating significantly extends the battery’s life. To deal with the combustion issue, the coating greatly limits the tiny needlelike structures — or dendrites — that pierce the separator between the battery’s positive and negative sides. In addition to ruining the battery, dendrites can create a short circuit within the battery’s flammable liquid. Lithium-ion batteries occasionally have the same problem but dendrites have been a non-starter for lithium metal rechargeable batteries to date. Dendrites also have prevented lithium metal batteries from being used in what may be the next generation of electric vehicles.

Superconductivity in a Nickel Oxide MaterialTBMG-3568912/01/2019
Scientists have made the first nickel oxide material that shows clear signs of superconductivity — the ability to transmit electrical current with no loss. Also known as a nickelate, it's the first unconventional superconductor that is very similar to copper oxides, or cuprates, which indicated that superconductors could someday operate at near-room-temperature and revolutionize electronic devices, power transmission, and other technologies. Those similarities may show that nickelates could also superconduct at relatively high temperatures.

Diagnose Lithium BatteriesTBMG-3458706/01/2019
Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To better analyze the causes of malfunctions and premature failure of such batteries, researchers have developed a technique that visualizes the distribution of active lithium on the anode and differentiates between dendrites and “dead” lithium. The technique makes use of a fluorescent dye.
