Office Action

§102
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. 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. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Makino et al. (hereinafter “Makino”) (U.S. Pub. No. 2017/0301947 A1) . Regarding claim s 1 and 9 , Makino teaches a solid electrolyte composition including an electrolytic polymerizable compound and an inorganic solid electrolyte (see paragraph 54). The inorganic solid electrolyte may comprise a sulfide-based inorganic solid electrolyte (see paragraph 60). As an exemplary sulfide-based inorganic solid electrolyte, Li 10 GeP 2 S 12 may be used (see paragraph 68). The electrolytic polymerizable compound may comprise trimethylpropane tri(meth)acrylate (see paragraphs 151, 152 and 160). Regarding claim 4 , Makino teaches that t he content of the electrolytic polymerizable compound may be 0. 1 part s by mass or more and 20 parts by mass or less with respect to 100 parts by mass of the inorganic solid electrolyte (see paragraph 303). Regarding claim 5 , Makino teaches that the inorganic solid electrolyte layer may further contain a lithium salt (see paragraph 376). Inorganic fluoride salts such as LiPF 6 and LiBF 4 may be used (see paragraph 380). Regarding claim 6 , Makino teaches that the content of the lithium salt may be 5 parts by mass or more and 20 parts by mass or less with respect to 100 parts by mass of the inorganic solid electrolyte (see paragraph 394). Regarding claim 7 , Makino teaches that the solid electrolyte composition may comprise a dispersion medium (see paragraph 396). A romatic compound solvents includ ing dichlorobenzene may be used (see paragraph 401). Regarding claim 8 , Makino teaches that the inorganic solid electrolyte layer may further contain a polymerization initiator (see paragraph 353). Exemplary polymerization initiators include those described in paragraphs 135-208 of JP 2006-084049 A (see paragraph 356). Among these exemplary polymerization initiators is 2,2'-azobisisobutyronitrile (azobis-based compounds) (see paragraph 208 of JP 2006-084049 A ). Regarding claim 10 , Makino teaches th at a drying treatment may be carried out when forming the inorganic solid electrolyte layer. The drying temperature is not particularly limited, but is preferably 30° C or higher 200° C. or lower. When the compositions are heated in th is temperature range, it is possible to remove the dispersion medium and cause the compositions to fall into a solid state (self-supporting) (see paragraph 460). Regarding claim 11 , Makino teaches that the solid electrolyte layer may be formed to have a thickness that is 3 to 400 μm (see paragraph 52). Regarding claims 12 , 13 , 15 and 20 , Makino teaches that a secondary battery electrode sheet may be manufactured by applying the solid electrolyte composition onto a positive electrode sheet , heat ing at 80° C for one hour, and then, furthermore, heat ing at 110° C for one hour. After that, a composition for a secondary battery negative electrode may be applied onto the dried solid electrolyte composition, heated at 80° C for one hour, and then, furthermore, heated at 110° C for one hour (see paragraph 533). Regarding claim 1 4 , Makino teaches that the solid electrolyte layer may be formed to have a thickness that is 3 to 400 μm (see paragraph 52). Regarding claim 16 , Makino teaches that a lithium single body or lithium alloys such as lithium aluminum alloys may be used as a negative electrode active material (see paragraph 439). Regarding claim 17 , Makino teaches that t he thickness of the negative electrode active material layer may be 3 to 400 μm (see paragraph 52) . Regarding claim 18 , Makino teaches that the positive electrode active material may comprise a transition metal oxide such LiCoO 2 , LiNi 0.33 Co 0.33 Mn 0.33 O 2 Li g Ni 0.8 Co 0.15 Al 0.05 O 2 (see paragraph s 409 , 419 and 422 ) Regarding claim 1 9 , Makino teaches that t he thickness of the positive electrode active material layer may be 3 to 400 μm (see paragraph 52) .
