Technical Field
The invention belongs to the technical field of organic batteries, and particularly relates to a chlorinated ether electrolyte and application thereof.
Background
Since the lithium metal anode has a higher theoretical capacity (3862mA h g)-1) At lower electrochemical potentials (-3.040Vvs SHE), Lithium Metal Batteries (LMBs) are rapidly developing. However, lithium metal can react with conventional carbonate electrolytes because of its high activitySevere side reactions that induce the formation of lithium dendrites. The growth of lithium dendrites may puncture the separator, causing a short circuit in the battery.
In order to alleviate the above problems, ether-based electrolytes have been proposed for use in lithium metal batteries, which can provide high coulombic efficiency and long-term cycle stability. Although the ether electrolyte can effectively inhibit the growth of dendrites on the surface of the anode, its weak oxidation resistance and flame retardancy limit the practical application of the lithium metal battery.

Example 4:
bis (2-chloroethoxy) ethane and bis (fluorosulfonyl) imide lithium as a solute in example 2 are used to prepare a chlorinated ether electrolyte 2, and bis (fluorosulfonyl) imide lithium is weighed to prepare the chlorinated ether electrolyte 2, wherein the addition amount of the salt and the ether solvent is 1: 1.6 (salt: ether solvent, molar ratio).

It can be seen from the above that, under the condition of a higher salt-to-solvent ratio, the chlorinated ether electrolyte can stably operate under a high voltage because of its excellent inherent oxidation resistance, whereas the conventional ether electrolyte has poor oxidation resistance and is subject to a severe oxidation phenomenon.
Example 6:
this example provides a conventional ether electrolyte, which comprises the following components: the electrolyte solvent is a traditional ether solvent (ethylene glycol diethyl ether), the solute is lithium bis (fluorosulfonyl) imide, and the diluent is 1,1,2, 2-tetrafluoroethyl-2, 2,3, 3-tetrafluoropropyl ether; the lithium bis (fluorosulfonyl) imide, a solvent and a diluent are weighed to prepare a traditional ether electrolyte 3, and the addition amount of the ether solvent and the diluent is 1: 3 (salt: ether solvent: diluent, molar ratio).

Test results referring to fig. 7, the chlorinated ether electrolyte 3 has good cycle performance at a voltage of 4.6V, compared to the conventional ether electrolyte 3.
It can be seen from the above that after the diluent beneficial to forming the protective layer is added, the conventional ether electrolyte 3 still undergoes an obvious oxidation phenomenon at a high voltage of 4.6V, and compared with the chlorinated ether electrolyte 3, the cyclic effect is better, which indicates that the chlorinated ether solvent has better high-voltage resistance and cyclic stability at a high voltage of 4.6V.
Example 10:
the chlorinated ether electrolyte 3 of example 2, which is bis (2-chloroethoxy) ethane, and which has a salt/chlorinated ether solvent/diluent ratio of 1: 1.6: 3 (salt/chlorinated ether solvent/diluent, molar ratio), was selected as the subject of the present example, and the conventional ether electrolyte 3 of example 6 was used as a control.
