Solid-electrolyte interphase formation process on Li2TiSiO5 anode in LiPF6-based carbonate electrolyte

Solid Electrolyte Interphase Formation on Silicon and Lithium Titanate Anode Materials in Lithium-Ion Batteries

Aiming at an improved knowledge of the formation of the solid electrolyte interphase (SEI), as basis for the safe and efficient use of new anode materials, we investigated the SEI formation on silicon and lithium titanate (LTO) anodes by electrochemical impedance spectroscopy (EIS) and ex situ X-ray photoelectron spectroscopy (XPS) measurements. While the EIS measurements performed at equidista...

Electrolyte and Solid-Electrolyte Interphase Layer in Lithium-Ion Batteries

The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...

A Review of Solid Electrolyte Interphases on Lithium Metal Anode

Lithium metal batteries (LMBs) are among the most promising candidates of high-energy-density devices for advanced energy storage. However, the growth of dendrites greatly hinders the practical applications of LMBs in portable electronics and electric vehicles. Constructing stable and efficient solid electrolyte interphase (SEI) is among the most effective strategies to inhibit the dendrite gro...

How Solid-Electrolyte Interphase Forms in Aqueous Electrolytes.

Solid-electrolyte interphase (SEI) is the key component that enables all advanced electrochemical devices, the best representative of which is Li-ion battery (LIB). It kinetically stabilizes electrolytes at potentials far beyond their thermodynamic stability limits, so that cell reactions could proceed reversibly. Its ad hoc chemistry and formation mechanism has been a topic under intensive inv...
