Since the commercialization of lithium ion batteries (LIBs), layered transition metal oxides (LiMO2, where M = Co, Mn, Ni, or mixtures thereof) have been materials of choice for LIB cathodes. During cycling, the transition metals change their oxidation states, an effect that can be tracked by detecting energy shifts in the X-ray absorption near edge structure (XANES) spectrum. X-ray absorption ...

A reduced-order model ROM is developed using proper orthogonal decomposition POD for a physics-based lithium-ion battery model. The methodology to obtain the proper orthogonal modes and to analyze their optimality is included. The POD-based ROM for a lithium-ion battery is used to simulate a charge/discharge process and the behavior of a battery pack. Compared to the physics-based model, the co...

For the simulation of protocols and algorithms of mobile devices, an ideal energy source, i.e. a battery with linear charge and discharge characteristics, is often assumed. However, real batteries like lithium-ion cells show nonlinear behavior, taking Rate Capacity Effect and Recovery Effect into account. The battery model presented by Rakhmatov and Vrudhula models non-linear battery behavior a...

Traditionally it has been assumed that battery thermal management systems should be designed to maintain the temperature around room temperature. That is not always true as lithium-ion (LIB) R&D pivoting towards development of high energy density and fast charging batteries. Therefore, necessary have a comprehensive review considerations for LIBs targeted charging, i.e., optimal condition, phys...

It is important for policymakers and industry practitioners to understand the factors that influence evolution of a technology's knowledge base, i.e., its trajectory. The literature on technologies their underlying bases suggests technological innovation takes place in an incremental cumulative manner along certain trajectories. We extend this by not only focusing design hierarchy knowledge, bu...

Recent advances in electrode materials, manufacturing processes, and safety features are enabling Li-ion battery (LIB) designs to better support energy storage needs for the emerging all-electric aviation market. Increases cell specific energy, improved fast charge discharge rate capability, extended cycle-life required next-generation platforms that consist of more-electric, hybrid, aircraft d...

Integration of Na-ion batteries (NIBs) as a complementary energy storage device to the presently dominating Li-ion battery (LIB) technology is must, considering cost and sustainability issues lithium. However, despite important laboratory-scale achievements concerning electrodes electrolytes, improvements needed for realizing devices meet users demands are being relatively slow. More specifical...

This year, the battery industry celebrates the 25th anniversary of the introduction of the lithium ion rechargeable battery by Sony Corporation. The discovery of the system dates back to earlier work by Asahi Kasei in Japan, which used a combination of lower temperature carbons for the negative electrode to prevent solvent degradation and lithium cobalt dioxide modified somewhat from Goodenough...

Heat generation and therefore thermal transport plays a critical role in ensuring performance, ageing safety for lithium-ion batteries (LIB). Increased battery temperature is the most important accelerator. Understanding managing operation thus multiscale challenge, ranging from micro/nanoscale within single material layers to large, integrated LIB packs. This paper includes an extended literat...

Lithium ion batteries (LIB) can rupture and result in thermal runaway battery fires. In the process of transporting lithium using trains, massive collection cause train fire pose significant danger to public. This is especially critical when occurs amid a heavily populated metropolitan environment. paper reports 3D analysis warehouse with possible due LIB propagation at rail yard. Six cases clo...
