Abstract:

Understanding the side reactions occurring inside lithium-ion cells remain a significant challenge, presenting opportunities for innovation. In this context, we developed a coupled 1H NMR (nuclear magnetic resonance) and dQ/dV (differential capacity) analysis method aimed at enhancing our understanding of these reactions during the formation cycle. Using deuterated acetonitrile as an extraction solvent, we measured the relative consumption of electrolyte components inside different electrolyte, including in 1.2M LiPF6 EC:EMC 3:7 2% VC and 1.2M LiPF6 EC:EMC 3:7 2% VC + 1% DTD electrolytes at di

Abstract:

Recently, a few studies have shown that the introduction of liquid crystals (LCs) in polymer electrolytes would lead to an increase in the chain mobility and the ionic conductivity. It is believed that this enhancement of the polymer electrolyte performance is greatly influenced by the order parameter of the liquid crystal in this system. In this study, a deuterated 4-pentyl-4-cyano-biphenyl (5CB-d2) nematic liquid crystal-doped polyvinyl alcohol (PVA) polymer electrolyte were prepared. The orientational order of the nematic liquid crystal is then investigated via the quadrupolar splittings of

The adaptation of neutron scattering methods for studying the microstructure of electrode materials of lithium-ion batteries was continued in order to improve their characteristics with respect to specific energy. Using small-angle scattering of thermal neutrons, the effect of conductive carbon additives (graphene and graphene oxide) on the porous structure of electrodes made from LiFePO4, Li4Ti5O12 and LiNiMnCoO2 was studied. To separate the scattering by closed and open pores, the electrodes were wetted with a typical liquid electrolyte with a deuterated liquid carrier (dimethyl carbonate),

Abstract:

A Li-ion battery (LIB) is the core component of energy stroage systems for space applications. To ensure performance stability and durability, it is crucial to understand the impact of cosmic radiations on LIB components and identify the underlying degradation mechanisms. Protons (H+), predominant species in cosmic rays, introduce defects in a crystalline structure, such as Frenkel pairs [1]. Graphite-based anodes are critically affected by these defects, influencing the formation of the solid-electrolyte interphase (SEI) and dead Li. Therefore, analyzing Li distribution in operating batteries

Evidence is cited from the research literature on metals containing absorbed deuterium supporting the hypothesis that the excess heat episodes observed over the past 25 years are the result of exothermic deuteron stripping reactions with atomic nuclei of the absorbing metal.
