Lithium-ion batteries are the primary power source in electric vehicles, and the prognosis of their remaining useful life is vital for ensuring the safety, stability, and long lifetime of electric vehicles. Accurately establishing a mechanism model of a vehicle lithium-ion battery involves a complex electrochemical process. Remaining useful life (RUL) prognostics based on data-driven methods ha...

Advanced electrochemical batteries are becoming an integral part of a wide range of applications from household and commercial to smart grid, transportation, and aerospace applications. Among different battery technologies, lithium-ion (Li-ion) batteries are growing more and more popular due to their high energy density, high galvanic potential, low self-discharge, low weight, and the fact that...

The performance, safety, and reliability of Li-ion batteries are determined by a complex set of multiphysics, multiscale phenomena that must be holistically studied and optimized. This paper provides a summary of the state of the art in a variety of research fields related to Li-ion battery materials, processes, and systems. The material presented here is based on a series of discussions at a r...

The aqueous Al-ion battery has achieved great progress in recent years. It now shows comparable performance to that of even non-aqueous batteries. However, it also relatively low energy output and there is limited general understanding the mechanism behind this restriction its practical application. Thus, development a high-performance cathode material demand. Herein, high-capacity single-walle...

Lithium ion secondary batteries have a high voltage and a high energy density, as shown in Fig. 1, and are widely used in mobile devices such as cell phones, notebook PCs and PDAs. However, since lithium ion secondary batteries use a flammable organic liquid electrolyte, there is a risk of explosion or fire. Fire accidents can also occur due to contamination during production or from overchargi...

In Li-ion batteries (LIBs), a memory effect has been revealed in two-phase electrode materials such as olivine LiFePO4 and anatase TiO2, which complicates the two-phase transition and influences the estimation of the state of charge. Practical electrode materials are usually optimized by the element doping strategy, however, its impact on the memory effect has not been reported yet. Here we fir...

Fossil fuels are our major source of energy, but they are depleting quickly. They also create major environmental issues such as climate change by causing the emission of carbon dioxide and other greenhouse gases. As a result, clean and renewable sources of energy such as solar, nuclear and wind are being considered as alternatives to fossil fuels. Some renewable energy sources are intermittent...

The diffusion of ions in solid materials plays an important role in many aspects of materials science such as the geological evolution of minerals, materials synthesis, and in device performance across several technologies. For example, the realization of multivalent (MV) batteries, which offer a realistic route to superseding the electrochemical performance of Li-ion batteries, hinges on the d...

The ultimate goal of this project is to develop a viable C-coating process of the current collector in order to improve the overall power performance of the electrode of Li-ion batteries. During this third-year period, the performance of different thickness of carbon coating on Al foil is compared. The result shows that only the samples with sufficient thickness to form conductive channel on th...
