The Li–Sn phase diagram shows the existence of seven intermetallic phases: Li2Sn5, LiSn, Li7Sn3, Li5Sn2, Li13Sn5, Li7Sn2 and Li22Sn5 [4]. However, cycling performance of these alloys rapidly deteriorates due to a large Li-driven volume change (up to 300% when 4.4Li per Sn atom...

the maximum Li-containing phase of the Li–Si binary phase diagram (Li22Si5) and each Li metal binary phase as suggested by Goward et al. (Li17M4 [M = Ge, Sn, and Pb] rather than Li22M5).22 In this section, the electrochemical properties of the Group IV elements and their ...
Currently Li17Si4 is the Li-richest phase in the binary Li-Si phase diagram, and it has been shown that its crystal structure is closely related to another Li-rich phase, Li21Si5 [5]. In both compounds there are four sites of higher symmetry 4a (0, 0, 0), 4b (1/2, 1/2, 1/...
In the subsequent work, we study Li–Sn and Li–Sb intermetallics in the context of alloy anodes for LIBs. A rich phase diagram of Li–Sn is present, exhibiting a variety of new phases. The calculated voltages show excellent agreement with previously reported cycling measurements and a ...

searches can result in an efficient location of stable stoichiometries. One of the recent studies on Li-Sn47employed such an algorithm and refined solutions with follow-up evolutionary searches at select compositions. Given the richness of the Li-Sn phase diagram and the complexity of the known...
A systematic, XRD study of the LiTFSI–succinonitrile phase diagram between − 100 and + 80 °C has been undertaken in an attempt to better understand the properties of these potential electrolyte materials. Access through your organization Check access to the full text by signing in through yo...
