To the average person, lithium-ion technology, at least until the last year or so, was represented by the black-box-like batteries in high-end consumer devices such as laptop computers. Mobile phone batteries use similar chemistry, although in that case the batteries are often lithium-polymer types that are frequently described as if they constitute an entirely different technology. The mystiqu...

Nowadays, lithium-ion battery is the focus of research in the new energy industry, and SOC (State of Charge) is one of the key studies in the study of lithium-ion battery, the estimation and calculation of SOC is directly related to the efficiency and safety of the use of lithium-ion battery, a good SOC estimation and calculation method can make the work of lithium-ion battery more secure, and ...

Pham, Huan Le M.S.M.E., Purdue University, December 2013. Health Diagnosis of Lithium-ion Battery Cell Using Vibration-based Test and Analysis. Major Professor: Dr. Douglas E. Adams, School of Mechanical Engineering. With their superior advantages of high capacity and low percentage of self-discharge, lithium-ion batteries, which are most commonly used as power sources for hand-held electronic ...

Polymer composite electrolytes (PCEs), i.e., materials combining the disciplines of polymer chemistry, inorganic and electrochemistry, have received tremendous attention within academia industry for lithium-based battery applications. While PCEs often comprise 3D micro- or nanoparticles, this review thoroughly summarizes prospects 2D layered inorganic, organic, hybrid nanomaterials as active (i...

Suppressing dendrite formation at lithium metal anodes during cycling is critical for the implementation of future lithium metal-based battery technology. Here we report that it can be achieved via the facile process of immersing the electrodes in ionic liquid electrolytes for a period of time before battery assembly. This creates a durable and lithium ion-permeable solid-electrolyte interphase...

Lithium battery is a reliable source for mobile, computers and electric vehicles. However, the internal chemical reaction of lithium battery is complex and susceptible to external influences, such that the traditional model-driven approach cannot model it accurately. In this paper, based on the data-driven approach, an expectation maximization algorithm is proposed to model a class of lithium b...

Lithium-based battery technology offers performance advantages over traditional battery technologies at the cost of increased monitoring and controls overhead. Multiple-cell Lead-Acid battery packs can be equalized by a controlled overcharge, eliminating the need to periodically adjust individual cells to match the rest of the pack. Lithium-based based batteries cannot be equalized by an overch...
