An Electrolyte For Use In An Electrochemical Battery
Abstract: The present invention relates to an electrolyte for use in an electrochemical battery. The electrolyte comprises 1 M Lithium hexafluorophosphate (LiPF6) mixed in a solution of Ethylene Carbonate (EC) and Ethyl methyl carbonate (EMC). The electrolyte further comprises 1% Lithium Difluoro(oxalato)borate (LiDFOB) for formation of uniform Cathode-Electrolyte Interphase (CEI) on a surface of a positive electrode of an electrochemical battery and Solid Electrolyte Interphase (SEI) on a surface of a negative electrode of the electrochemical battery, 1% Vinylene carbonate (VC) for improvement in formation of the SEI, 3% 1, 3-Propane sultone (PS) for suppressing formation of the gas in the electrolyte, 2% Succinonitrile (SN) for suppressing hydrolysis reaction of LiPF6 with water, and 2% 1,3,6-Hexanetricarbonitrile (HTCN) for providing strong interaction between surface metal atoms and nitrile groups.

Specification
WE CLAIM:
1. An electrolyte for use in an electrochemical battery, comprising:
1 M Lithium hexafluorophosphate (LiPF6) mixed in a solution of Ethylene Carbonate (EC) and Ethyl methyl carbonate (EMC);
1% Lithium Difluoro(oxalato)borate (LiDFOB) for formation of uniform Cathode-Electrolyte Interphase (CEI) on a surface of a positive electrode of an electrochemical battery and Solid Electrolyte Interphase (SEI) on a surface of a negative electrode of the electrochemical battery;
1% Vinylene carbonate (VC) for improvement in formation of the SEI;
3% 1, 3-Propane sultone (PS) for suppressing formation of the gas in the electrolyte;
2% Succinonitrile (SN) for suppressing hydrolysis reaction of LiPF6 with water; and
2% 1, 3, 6-Hexanetricarbonitrile (HTCN) for providing strong interaction between surface metal atoms and nitrile groups.
2. The electrolyte as claimed in claim 1, wherein EC and EMC are used in a ratio of 3:7 v/v.
3. The electrolyte as claimed in claim 1, wherein the electrochemical battery is a lithium-ion battery.
4. The electrolyte as claimed in claim 1, wherein the electrolyte exhibits electrochemical stability up to 5.2 V.
