Election/Restrictions
The election of species has been withdrawn.
Claim Objections
Claim 2 is objected to because of the following informalities:The symbol on line 4 should be removed. Appropriate correction is required.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1-2 and 4-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ji et al. (US 2020/0144672). Ji et al. teaches in [0010-0011], that the phosphorus-based compound can be Formula (B):

[teaching a pyrrolidine]. Ji et al. teaches in [0073], that the concentration of the phosphorus-based compound in the electrolyte solution can be 0.1-10 wt% or 1-5 wt% or 1-3 wt%. Ji et al. teaches in [0158], a battery comprising an anode comprising a Si-based material, a cathode and an electrolyte system comprising a phosphorus-based compound, a solvent and a lithium salt. Ji et al. teaches in [0079], that the cathode can comprise LiCoO2, LiNi0.6Co0.2Mn0.2O2, etc.
Claim(s) 1-3, 5 and 7-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kodama et al. (JP 2014-127354, translation given). Kodama et al. teaches in the abstract, a nonaqueous secondary battery capable of achieving both high overcharge prevention properties and deterioration suppression of battery performance even if a positive electrode potential is used at high potential comprising an electrolyte solution comprising at least one of nitrogen containing compound additive having a specific structure such as

[a pyrazolyl group]. Kodama et al. teaches in Example 1, an electrolyte solution for battery (1) where the component (A) is added to the solvent shown in Table 1 in the amount of 0.1, 0.5, 3, 5 and 10wt% and the electrolyte comprising 1M of LiPF6 or LiBF4 is added. Kodama et al. teaches a battery comprising a positive electrode comprising LiNi1/3Mn1/3Co1/3O2; a negative electrode and the electrolyte solution.
