The lithium–tin alloy electrode, as an artificial solid–electrolyte interphase (SEI) material with outstanding electrochemical properties, is promising to realize advanced next-generation lithium batteries. Experimental explorations on Li–Sn alloy have already achieved great success, while theoretical understanding on the mechanism of lithium-ion transport is still lacking. In this work, we carried out first-principles simulations and developed a theoretical methodology to reveal how a lithium ion diffuses in different lithium–tin phases and further elaborated the origin of low diffusion barriers. The simulation results indicate that two kinds of diffusion modes, interstitial and vacancy diffusion, will compete with each other with the increase in lithium concentration. Furthermore, the underlying mechanisms of direct hopping and coordinate process are also different in different Li–Sn/In phases. It is interesting to discover that during the lithiation process of alloy phases, the high-rate transport channel will gradually transform from the interstitial direct-hopping to vacancy mechanism and finally to the interstitial knock-off mechanism. This work provides a thorough theoretical understanding on lithium-ion transportation, further opening up the possibility of synthesizing or modifying SEI materials with enhanced Li conductivity in novel Li-ion battery designs.

“…Lowe et al suggested early elective surgery in most patients with traumatic CAF because of the high incidence of late complications and the low morbidity and mortality associated with elective repair 2 . Early reports of surgery documented high recurrence rates 3 but this has been overcome since the advent of coronary artery bypass techniques 21 . The operation of choice is to obtain secure obliteration of the fistula by proximal and distal ligation in association with the insertion of a graft distal to the fistula 3 .…”

Objective: To present a case of traumatic coronary artery fistula caused by blunt injury. Clinical features: A previously healthy 20‐year‐old motor cyclist was involved in a motor vehicle accident. He suffered acute myocardial infarction secondary to a traumatic coronary artery fistula (CAF). His other injuries included a fractured left clavicle, bilateral small pulmonary contusions and pneumothoraces, pneum‐omediastinum and a small subcapsular haematoma of the liver. Intervention and outcome: He was managed conservatively. Recovery was complicated only by pericarditis and he was well one year after the injury. Conclusion: Traumatic CAF may result from blunt chest trauma and may be diagnosed from history, physical examination, and ECG changes. An echocardiogram should be performed in patients with positive ECG findings or the development of a new continuous murmur. Coronary angiography remains the gold standard but is rarely indicated in the acute situation. Regular follow up is required as traumatic CAF has a high incidence of late complications. With symptomatic CAF, the recommended treatment of surgical repair has a high success rate with few complications.
