Non-aqueous electrolyte solution containing phosphonosulfonic acid compound, and lithium secondary battery |
摘要 |
The invention provides a non-aqueous electrolyte solution containing a phosphonosulfonic acid compound represented by formula (I):
wherein, in formula (I), R1, R2 and R3 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a haloalkyl group having 1 to 6 carbon atoms, a phenyl group, a benzyl group, or a group represented by formula (II); R4 and R5 each independently represent a hydrogen atom, a halogen atom, or an alkyl group having 1 to 6 carbon atoms; and n represents an integer from 1 to 6; andwherein, in formula (II), R6, R7 and R8 each independently represent an alkyl group having 1 to 6 carbon atoms, a phenyl group, or a benzyl group; m represents an integer from 0 to 2; and * represents a position of bonding with the oxygen atom in formula (I).; |
