“…Our results compared with previous measurements [80][81][82][85][86][87][88][89][90]] between 2 and 5A MeV reveal certain inconsistencies. If combined with the Lin et al and Tumino et al data [80,81] can indicate the possible presence of a broad resonance at E p = 3.7 MeV. The interpretation of the results was considered in a CDCC approach.…”

“…The results did not change appreciably from fit to fit and average results were integrated over angle for deducing the reaction cross sections, which are included in Fig. 9 Present p( 6 Li, 3 He) 4 He reaction cross section measurements as a function of energy, designated by the boxes, compared with previous values [80][81][82][85][86][87][88][89][90]. It should be noted that the data of Refs.…”

“…[12,13], as complementary to a global understanding of the 6 Li + p reaction at low energies into a CDCC framework. These data also served to clarify inconsistencies on various measurements performed before [81][82][83][84][85][86][87][88][89][90].…”

Global descriptions and decay rates for continuum excitation of weakly bound nuclei

In this work we will present an overview of our global studies on continuum excitations induced by protons, for the weakly bound nuclei 6 Li, 7 Li and 9 Be, presenting strong clustering modes. Measurements are made in inverse kinematics and extensive simulations have been developed, to corroborate the analysis and interpretation of the results. The focus of the measurements is on the breakup reaction, but simultaneously this research is complemented by the study of all involved reaction channels, including elastic scattering. In this respect our theoretical interpretation in a Continuum Discretized Coupled Channel approach can be fully validated. Between our sound conclusions we can underline the following: the non reciprocity between the strengths of the breakup probability and the coupling to continuum; the experimental validation of a continuum discretization for three body Continuum Discretized Coupled Channel theories; and last but not least the unique possibility for deducing continuum decay rates of borromean nuclei in proton induced studies, by considering the kinematics of the target recoil. Other specific conclusions for each system will be discussed.

“…Below 2200 keV proton energy, a window without overlap of the 6 Li(p, 3 He) 4 He peak with typical battery elements such as Mn exists, which was used to test the existing cross-sections for this reaction using thin films. The Chia-Shou Lin data [43] for 147.1 • appear to match the experimental spectra at 150 • , but they offer only a few data points. The Bashkin data [44] offer more data points, but were found to be largely incorrect, at least for 150 • .…”

Quantitative Lithiation Depth Profiling in Silicon Containing Anodes Investigated by Ion Beam Analysis

The localisation and quantitative analysis of lithium (Li) in battery materials, components, and full cells are scientifically highly relevant, yet challenging tasks. The methodical developments of MeV ion beam analysis (IBA) presented here open up new possibilities for simultaneous elemental quantification and localisation of light and heavy elements in Li and other batteries. It describes the technical prerequisites and limitations of using IBA to analyse and solve current challenges with the example of Li-ion and solid-state battery-related research and development. Here, nuclear reaction analysis and Rutherford backscattering spectrometry can provide spatial resolutions down to 70 nm and 1% accuracy. To demonstrate the new insights to be gained by IBA, SiOx-containing graphite anodes are lithiated to six states-of-charge (SoC) between 0–50%. The quantitative Li depth profiling of the anodes shows a linear increase of the Li concentration with SoC and a match of injected and detected Li-ions. This unambiguously proofs the electrochemical activity of Si. Already at 50% SoC, we derive C/Li = 5.4 (< LiC6) when neglecting Si, proving a relevant uptake of Li by the 8 atom % Si (C/Si ≈ 9) in the anode with Li/Si ≤ 1.8 in this case. Extrapolations to full lithiation show a maximum of Li/Si = 1.04 ± 0.05. The analysis reveals all element concentrations are constant over the anode thickness of 44 µm, except for a ~6-µm-thick separator-side surface layer. Here, the Li and Si concentrations are a factor 1.23 higher compared to the bulk for all SoC, indicating preferential Li binding to SiOx. These insights are so far not accessible with conventional analysis methods and are a first important step towards in-depth knowledge of quantitative Li distributions on the component level and a further application of IBA in the battery community.
