Abstract
There is provided a non-aqueous electrolyte battery including a positive electrode, a negative electrode capable of occluding and emitting lithium ions, and a non-aqueous electrolyte containing lithium ion, in which the above-mentioned non-aqueous electrolyte is a solution containing at least one kind of the phosphazene derivatives selected from the group consisting of the phosphazene derivatives expressed by the following formula:(R1O)3P═N—SO3R1,where R1 denotes a same or different monovalent organic group andphosphazene derivatives expressed by the following formula:(R2O)3P═N—SO2—N═P(OR2)3,where R2 denotes a same or different monovalent organic group, anda lithium salt, which is capable of controlling the evaporation and decomposition of an electrolyte whose base is an organic solvent in a wide range of temperature, excels in high-temperature preservability, and exhibit superior cell performance with reduced danger of bursting and ignition.
