Multivalent ion batteries (MIBs) have received much attention as alternatives to the current lithium-ion batteries (LIBs) because of their high energy d. and the possibility of using raw materials with high natural abundance. However, the mechanochem. stability and key electrochem. performance of MIB electrodes are easily impaired during cycling by the large volume expansion of active materials and sluggish ion transport, raising the necessity of developing advanced binder designs. Herein, we report a systematic investigation of polysaccharide and polyacrylic acid binders with carboxylic acid functional groups for MIBs based on Mg2+, Ca2+, Zn2+, and Al3+ in comparison with their monovalent counterpart. These binders with carboxylic acid functional groups form a rigid passivation layer on the electrode surface via the so-called egg-box mechanism involving the multivalent cations, imposing resistance and shortening the cycle life of the MIB cells. The series of comparative analyses provide useful information on the effect and design of popular carboxylic acid-functionalized binders for incorporation in MIBs. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2HPLC of Formula: 112-49-2).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.HPLC of Formula: 112-49-2
