Iodine as a Temperature‐Responsive Redox Shuttle Additive for Swelling Suppression of Lithium‐Ion Batteries at Elevated Temperatures
Authors: Park Seong‐Hyo , Kim Hyeon Jin , Jeon Joomi , Choi Yongsu , Cho Jeong‐Ju , Lee Hochun 
Published: July 2016

AbstractThe swelling issue by gas evolution at elevated temperatures (85–90 °C) is one of the major challenges related to current Li‐ion batteries (LIBs). We herein demonstrate that iodine (I2) as a redox shuttle additive, when its dose is properly determined, can suppress the swelling behavior of LiCoO2/graphite Al‐pouch cells during storage at 90 °C without sacrificing other cell performances. This approach is based on two findings: 1) swelling during 90 °C storage is severe only when the cells are fully charged, and 2) the shuttling reaction of I2 can be tuned to be activated only when the temperature is as high as 90 °C by employing an appropriate amount of I2. Therefore, when a fully charged cell is exposed to a temperature of 90 °C, the self‐discharge by I2 lowers the state of charge of the cell, suppressing the swelling. This temperature‐responsive shuttling behavior of I2 is ascribed to the preferential adsorption of I2 on the cathode surface. It is also confirmed that inclusion of the I2 additive does not lead to deterioration in other aspects of cell performance, such as the discharge capacity or long‐term cyclability. Along with the improved cell performance, the low‐cost and environmental compatibility of I2 makes it a promising electrolyte additive for thermally robust LIBs.

Published: July 2016

AbstractCone calix[4]arenes and calix[6]arenes bearing two, three, and four short peptide units each having two chiral carbon atoms were prepared. The syntheses were performed by using an efficient modular approach that includes the Ugi preparation of the azido‐peptide followed by its reactions with the propargylated calixarenes under CuAAC (CuI‐catalyzed azide–alkyne cycloaddition) conditions. The three novel multitopic hosts were probed for their ability to bind metal ions by UV titration, and showed the highest complexation efficiency towards copper(II) and lead(II). These two cations possessed quite different complexation modes with copper(II) bound predominantly by multiple‐triazole sites, in contrast to lead(II), which is stabilized mainly by multiple interactions with amide groups of the peptide units. Circular dichroism data for the free chiral hosts, their equimolar mixtures with copper(II) perchlorate and lead(II) perchlorate, and for tertiary mixtures of all three compounds showed the formation of mono‐ and binuclear complexes, or a switching behavior, depending on the structure of the host and the addition order of the cations.
