High-performance lithium-metal batteries are achieved by using a glyme-based electrolyte enhanced with a LiNO3 additive and a LiFePO4 cathode. An optimal electrolyte formulation is selected upon detailed anal. of the electrochem. properties of various solutions formed by dissolving resp. lithium bis(fluorosulfonyl)imide (LiFSI), lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), and lithium bis(pentafluoroethanesulfonyl)imide (LiBETI) either in diethylene glycol di-Me ether or in triethylene glycol di-Me ether and by adding LiNO3. A thorough investigation shows evidence of efficient ionic transport, a wide stability window, low reactivity with lithium metal, and cathode/electrolyte interphase characteristics that are strongly dependent on the glyme chain length. The best Li/LiFePO4 battery delivers 154 mAh g-1 at C/3 (1 C=170 mA g-1) without any decay after 200 cycles. Tests at 1 C and 5 C show initial capacities of about 150 and 140 mAh g-1, a retention exceeding 70% after 500 cycles, and suitable electrode/electrolyte interphases evolution. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Name: 2,5,8,11-Tetraoxadodecane).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Name: 2,5,8,11-Tetraoxadodecane
