Sodium-oxygen.batteries(SOBs) have the poten.ial to provide en.rgy den.ities higher than.the state-ofthe-art Li-ion.batteries. However, con.rollin. the formation.of sodium superoxide(n.O_(2)) as the sole discharge product on.the cathode side is crucial to achieve durable an. efficien. SOBs. In.this work, the discharge efficien.y of two graphen.-based cathodes was evaluated an. compared with that of a commercial gas diffusion.layer. The discharge products formed at the surface of these cathodes in.a glyme-based electrolyte were carefully studied usin. a ran.e of characterization.techn.ques. n.O_(2) was detected as the main.discharge product regardless of the specific cathode material while small amoun.s of n._(2)O_(2).2H_(2)O an. carbon.te-like side-products were detected by X-ray diffraction.as well as by Raman.an. in.rared spectroscopies. This work leverages the use of X-ray diffraction.to determin. the actual yield of n.O_(2)which is usually overlooked in.this type of batteries. Thus, the proper quan.ification.of the superoxide formed on.the cathode surface is widely un.erestimated;even.though is crucial for determin.n. the efficien.y of the battery while elimin.tin. the parasitic chemistry in.SOBs. Here, we develop an.ex-situ an.lysis method to determin. the amoun. of n.O_(2) gen.rated upon.discharge in.SOBs by tran.mission.X-ray diffraction.an. quan.itative Rietveld an.lysis. This work un.eils that the yield of n.O_(2) depen.s on.the depth of discharge where high capacities lead to very low discharge efficien.y, regardless of the used cathode. We an.icipate that the methodology developed herein.will provide a con.en.en. diagn.sis tool in.future efforts to optimize the performan.e of the differen. cell compon.n.s in.SOBs.

目的:本实验研究了以非致死剂量脂多糖(Lipopolysaccharide,LPS)攻击半乳糖葡胺(D-galactosamin.,D-Galn.增敏小鼠的死亡是否伴有重要器官的凋亡特征。方法:实验组小鼠以LPS(0.05μg)与D-Galn.20mg)直接攻击,而对照组小鼠仅仅以LPS或D-Galn.在规定实验时间经乙醚麻醉后,取出脑、肾、心、脾、肺、肝,并立即匀浆和抽提Dn.,对所抽提的各器官的Dn.以常规琼脂糖凝胶电泳分析是否存在Dn.梯度现象;并测定血浆中乳酸脱氢酶和谷氨酸草酰乙酸转移酶,同时将Dn.片段化现象与小鼠致死作用的关联性在实验组和对照组间做比较。结果:LPS攻击B-Galn.敏的小鼠4h时,在所检测的器官中,仅仅肝脏可见到凋亡特征Dn.片段化现象,至7h时小鼠死亡。而仅用LPS或D-Galn.击的对照组小鼠,不仅全部存活而且肝脏Dn.分子完整。结论:LPS攻击B-Galn.敏的小鼠,肝脏是唯一出现Dn.片段化的靶器官,由细菌LPS引发小鼠的死亡,肝脏的损伤可能是关键的原因。
