TL;DR: In this article, the state-of-the-art advances in active materials, electrolytes and cell chemistries for automotive batteries are surveyed, along with an assessment of the potential to fulfil the ambitious targets of electric vehicle propulsion.

TL;DR: In this paper, the authors carried out a patent search using the patent database PatBase® to assess the development status of lithium-based batteries (LIB) technology and found disproportionately high growth rates in LIB patent applications over the last years compared to other selected energy-related technologies.

TL;DR: The major part of the observed overall specific capacity loss is reversible and induced by kinetic limitations, namely an impeded lithiation reaction during discharge, and the impact of parasitic reactions, such as oxidative electrolyte decomposition, on the irreversible capacity is negligible.

TL;DR: In this paper, the metal ion content in the electrolyte was measured using inductively coupled plasma/optical emission spectrometry (ICP-OES) technique to determine the metal dissolution behavior.

TL;DR: It is shown that the silicon thin film electrodes with an amorphous C layer showed a remarkably improved electrochemical performance in terms of capacity retention and Coulombic efficiency.
