SECONDARY BATTERY, ELECTROLYTE, AND APPARATUS COMPRISING THE SECONDARY BATTERY - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18208898 Titled 'SECONDARY BATTERY, ELECTROLYTE, AND APPARATUS COMPRISING THE SECONDARY BATTERY'
Simplified Explanation
The abstract describes a secondary battery and its electrolyte, as well as an apparatus that includes the battery. The battery includes an electrolyte that contains an organic solvent, specifically a cyclic carbonate and a chain carbonate. The mass ratio of the cyclic carbonate to the chain carbonate is between 25:75 and 32:68. The chain carbonate includes dimethyl carbonate, with a mass percentage of dimethyl carbonate in the chain carbonate between 9% and 50%. The mass percentage of a carboxylic acid ester in the organic solvent is less than 5%. This secondary battery is capable of providing excellent low-temperature power, long service life, and cycle performance.
Original Abstract Submitted
The present application provides a secondary battery, an electrolyte, and an apparatus including the secondary battery. The secondary battery of the present application includes an electrolyte, characterized in that the electrolyte includes an organic solvent, and the organic solvent includes a cyclic carbonate and a chain carbonate; the mass ratio of the cyclic carbonate and the chain carbonate is from 25:75 to 32:68; the chain carbonate includes dimethyl carbonate; the mass percentage of the dimethyl carbonate in the chain carbonate is greater than or equal to 9 wt % and less than 50 wt %; wherein based on the total mass of the organic solvent, the mass percentage of a carboxylic acid ester is less than 5 wt %. The secondary battery of the present application can simultaneously obtain excellent low-temperature power, long service life and cycle performance.
