Recent Advances in Nanoengineering of Electrode-Electrolyte Interfaces to Realize High-Performance Li-Ion Batteries

A suitable interface between the electrode and electrolyte is crucial in achieving highly stable electrochemical performance for Li-ion batteries,as facile ionic transport is required.Intriguing research and development have recently been conducted to form a stable interface between the electrode and electrolyte.Therefore,it is essential to investigate emerging knowledge and contextualize it.The nanoengineering of the electrode-electrolyte interface has been actively researched at the electrode/electrolyte and interphase levels.This review presents and summarizes some recent advances aimed at nanoengineering approaches to build a more stable electrode-electrolyte interface and assess the impact of each approach adopted.Furthermore,future perspectives on the feasibility and practicality of each approach will also be reviewed in detail.Finally,this review aids in projecting a more sustainable research pathway for a nanoengineered interphase design between electrode and electrolyte,which is pivotal for high-performance,thermally stable Li-ion batteries.

Absence of asymptomatic unruptured renal artery pseudoaneurysm on contrast-enhanced computed tomography after robot-assisted partial nephrectomy without parenchymal renorrhaphy

Objective:To assess the incidence of asymptomatic unruptured renal artery pseudoaneurysm(RAP)on contrast-enhanced computed tomography(CE-CT)after robot-assisted partial nephrectomy(RAPN)without parenchymal renorrhaphy.Methods:From May 2016 to December 2017,78 patients underwent RAPN for renal tumors.Inner suture was performed in the opened collecting system or renal sinus,whereas parenchymal renorrhaphy was not.For hemostasis,the soft coagulation system was used,and absorbable hemostats were placed on the resection bed.CE-CT was carried out within 7 days after surgery.Data on these patients were prospectively collected.A single radiologist determined the diagnosis of RAP.Results:Median(range)data were as follows:Patient age,65(19-82)years;radiographic tumor size,30(12-95)mm;operating time,166(102-294)min;warm ischemic time,16(7-67)min;and blood loss,15(0-4450)mL.One patient(1.6%)required a perioperative blood transfusion.No patient required conversion to open surgery or nephrectomy.CE-CT was carried out at median 6(3-7)days after surgery.CE-CT showed no RAP development in all 61 patients.Urinary leakage was not observed.One patient had acute cholecystitis,a postoperative complication classified as Clavien-Dindo grade higher than 3,which was treated with cholecystectomy.Positive surgical margin was identified in four patients(6.6%).Conclusion:RAPN using soft coagulation and absorbable hemostats without renorrhaphy appears to be feasible and safe.Our technique could eliminate the risk of RAP.
