How lithium dendrites form in liquid batteries

2019/10/25Insulating SEI layers worsen the uneven distribution of the electrical field within the anode and induce more dendrites to grow. The reaction between electrolyte and dendritic Li consumes electrolyte irreversibly, and the accumulation of insulating SEI layers produces "dead" Li that completely loses electronic contact with the anode ( 9 ).

Abstract: Study of Solid Electrolyte Interface (SEI)

Significant divergence of option as to the nature of SEI also exists in the literature despite the common agreement on the positive effects of SEI in prolonging the lithium ion battery cycling life. Moreover, numerous literature reports indicate that adding electrolyte additives to electrochemical cells can effectively modify the electrode surface layers composition and

Role of Crystal Symmetry in the Reversibility of Stacking

KIT

2017/9/15The fundamental processes during the SEI formation as well as its behavior during battery operation are very complex and up to know not yet fully understood. Therefore, we will use state-of-the art surface and interface characterization techniques to identify the main criteria of stable SEI layers to be able to drive a knowledge-based development of artificial SEI layers.

Failure progression in the solid electrolyte interphase (SEI)

Decoding Cancer Biology One Cell at a Time

2021/4/1Human tumors are composed of diverse malignant and nonmalignant cells, generating a complex ecosystem that governs tumor biology and response to treatments. Recent technological advances have enabled the characterization of tumors at single-cell resolution, providing a compelling strategy to dissect their intricate biology. Here we describe recent developments in single-cell

The Effect of an SEI Layer on Anode and Cathode Particles

Previous studies have highlighted the range of cathode particles that can be deposited by ALD, though the deposition of anode materials by ALD is more limited. The high conductivity coatings developed by Forge Nano have been found to inhibit the rate of SEI layer growth on anode surfaces.
