Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1525. 72 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9931-0. Lithium-ion battery (LIB) technology is currently the most promising candidate for power sources in applications such as portable...

Degradation mechanisms such as lithium plating, growth of the passivated surface film layer on the electrodes and loss of both recyclable lithium ions and electrode material adversely affect the longevity of the lithium ion battery. The anode electrode is very vulnerable to these degradation mechanisms. In this paper, the most common aging mechanisms occurring at the anode during the operation ...

The electrolyte infiltration is a critical step in the Lithium-ion battery (LIB) cell manufacturing process, impacting for instance solid interphase heterogeneity and ageing. rate effectivity are tied to porous mesostructure dimensions of electrodes separator, which mainly dictated by electrochemical performance requirements. We propose here use architectures with layers varying pore network pr...

To meet the load voltage and power requirements for various specific needs, a typical lithium–ion battery (LIB) pack consists of different parallel series combinations individual cells in modules, which can go as high tens connections each module, reaching hundreds even thousands at (HV) levels. The inhomogeneity among modules results imbalances during operation reduces overall system efficienc...

A sustainable, heat-resistant and flame-retardant cellulose-based composite nonwoven has been successfully fabricated and explored its potential application for promising separator of high-performance lithium ion battery. It was demonstrated that this flame-retardant cellulose-based composite separator possessed good flame retardancy, superior heat tolerance and proper mechanical strength. As c...

It is estimated that over 90% of people own a mobile phone. Although rare, lithium-ion battery explosions can cause varying degrees of thermal burn injury. Recently, selective enzymatic debridement has gained importance in the management of burn patients, thanks to its simplicity, minimum invasiveness and safety. In this work, we describe a case of a burn injury caused by the explosion of a lit...

Abstract The estimation of state health (SOH) a lithium-ion battery (LIB) is great significance to system safety and economic development. This paper proposes SOH method based on the SSA-Elman model for first time. To improve correlation rates between features capacity, combining median absolute deviation filtering Savitzky–Golay proposed process data. Based aging characteristics LIB, five with...

Sulfide-based all-solid-state lithium-ion batteries (LIBs) are promising replacements for conventional liquid electrolyte LIBs. However, their degradation mechanisms and analysis methods poorly understood. Herein, the mechanism of an argyrodite-type sulfide-based prototype LIB cell is reported. Furthermore, method using charge/discharge cycle tests at 100°C followed by disassembly cells before ...

In this paper, a model based condition monitoring technique is developed for lithium-ion battery condition monitoring. Here a number of lithium-ion batteries are cycled using two separate over discharge test regimes and the resulting shift in battery parameters is recorded. The battery models are constructed using the equivalent circuit methodology. The condition monitoring setup consists of a ...

Life cycle assessment studies of large-scale lithium-ion battery (LIB) production reveal a shift-of-burden to the upstream phase cell production. Thus, it is important understand how environmental impacts differ based on source and grade extracted metals. As lithium highly relevant several current next-generation chemistries, we reviewed effect varying grades in different sources (brine spodume...
