Design of a new lithium ion battery test cell for in-situ neutron diffraction measurements

In-Situ Neutron Studies of Electrodes for Li-Ion Batteries Using a Deuterated Electrolyte: LiCoO2as a Case Study

“…For instance, ~32 [28,29]. Other cells with similar characteristics have been used to investigate LiFePO4 [20], a perovskite-type electrode Li0.18Sr0.66Ti0.5Nb0.5O3 [30] and more recently, LiNi0.5Mn1.5O4 [31,32].…”

New Opportunities for Air Cathode Batteries; in-Situ Neutron Diffraction Measurements

“…However, the dimensions of the in-situ cell are significantly larger compared to standard coin cells to maximize the amount of electrode material exposed to the neutron beam; the outer cell diameter of the cell is 84 mm and usually accommodates rectangular-shaped electrodes of 1-2 g. Figures 1A,B show an expanded view of the in-situ cell and a sketch of the cell components and their position with respect to the incident neutron beam, respectively. Further details of the cell components and materials used to collect neutron diffraction patterns with an increased peak-to-background ratio may be found in previous publications (Roberts et al, 2013;Biendicho et al, 2014Biendicho et al, , 2015.…”

In situ methods for Li-ion battery research: A review of recent developments

“…The use of custom-made cells with low H-content components that mimic, for example, cylindrical 18650-type commercial batteries leads to a significant increase of the signal-to-noise ratio [89]. A common strategy to lower the H-content is the use of deuterated electrolytes and special fluorinated separators [89,96,97]. A remaining issue is however the presence of many cell components in the pathway of the neutron beam.…”

“…At this moment in time it remains challenging to obtain high-quality full pattern Rietveld refinements of in situ neutron diffraction data [91]. In an effort to resolve the aforementioned issues, several promising new battery cells for in situ neutron diffraction measurements have recently been proposed [90,91,94,96,98].…”
