Many studies have evaluated CO2 emission from batteries. However, the impact of Li-ion battery (LiB) degradation on emissions material through operation phases has not been sufficiently examined. This study aims to clarify dominant phase and general industrial LiBs repetitive cycle applications. We developed a model common LiB composition calculated by LCA method using IDEA database. Our simpli...
All-solid-state lithium ion batteries (LIB) are currently the most promising technology for next generation electrochemical energy storage. Many efforts have been devoted in past years to improve performance and safety of these devices. Nevertheless, issues regarding chemical mechanical stability different components still hinder substantial improvements. Pulsed laser deposition (PLD) has prove...
A precise interpretation of lithium-ion battery (LIB) heat generation is indispensable to the advancement and accomplishment thermal management systems for different applications LIB, including electric vehicles. The internal resistance a lithium titanate oxide (LTO)-based LIB was determined at state charge (SOC) levels current rates understand relationship between generation. Random pulse disc...
We present observations of the dwarf novae GW Lib, V844 Her, and DI UMa. Radial velocities of Hα yield orbital periods of 0.05332± 0.00002 d (= 76.78 m) for GW Lib and and 0.054643± 0.000007 d (= 78.69 m) for V844 Her. Recently, the orbital period of DI UMa was found to be only 0.054564± 0.000002 d (= 78.57 m) by Fried et al. (1999), so these are the three shortest orbital periods among dwarf n...
BACKGROUND The successful implementation of decision aids in clinical practice initially depends on how clinicians perceive them. Relatively little is known about the acceptance of decision aids by physicians and factors influencing the implementation of decision aids from their point of view. Our electronic library of decision aids (arriba-lib) is to be used within the encounter and has a modu...
میکروکاواک های نیمرسانا می توانند بستر مناسبی را برای ایجاد و مشاهده ی پدیده های غیرخطی اپتیکی نظیر تشکیل طرح های نوری و سالیتون های کاواک فراهم کنند که اهمیت مطالعه ی دینامیک معادلات ماکسول-بلاخ را در رژیم غیرخطی دوچندان می کند. بررسی دینامیک غیرخطی معادلات ماکسول- بلاخ برای توصیف لیزرزایی درکاواک های نیمرسانا بسیار حائز اهمیت می باشد چرا که در این سیستم معادلات، مقیاس های زمانی فمتوثانیه توجی...
Lithium (Li)-ion batteries (LIB) have governed the current worldwide rechargeable battery market due to their outstanding energy and power capability. In particular, the LIB’s role in enabling electric vehicles (EVs) has been highlighted to replace the current oil-driven vehicles in order to reduce the usage of oil resources and generation of CO 2 gases. Unlike Li, sodium is one of the more abu...
A stable Si-based anode with a high initial coulombic efficiency (ICE) for lithium-ion batteries (LIB) is critical for energy storage. In the present paper, a new scalable method is adopted in combination with giant nitrogen-doped graphene and micron-size electrode materials. We first synthesize a new type of freestanding LIB anode composed of micron-sized Si (mSi) particles wrapped by giant ni...
Today, lithium-ion batteries (LIBs) are ubiquitous in mobile phones, laptops, and other portable devices. The research community strives to further improve the LIB to increase electric driving distance and efficiency of both hybrid electric vehicles (HEVs) and fully electric vehicles (EVs). Conventional LIBs need to be strictly temperature controlled, most often cooled, to ca. 30°C, to ensure a...
Motion systems are important parts of technical products. Those are often composed using mechanisms and gears. However, the worldwide existing knowledge about mechanisms in theory and practice is mostly scattered and only fragmentarily accessible for users like students, engineers and scientists. It does not comply with today’s requirements concerning a rapid information retrieval. This paper p...
