CTNF 18/463,954 CTNF 75068 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Foreign Priority Documents The China foreign priority document(s) 202110305372.5 , submitted under 35 U.S.C. § 119 (a)-(d), was/were been received on February 2, 2026 and placed of record in the file. Information Disclosure Statement The information disclosure statements filed September 8, 2023 has/have been received and complies with the provisions of 37 CFR 1.97, 1.98 and MPEP § 609. Accordingly, the information disclosure statement(s) is/are being considered by the examiner, and an initialed copied is attached herewith. Allowable Subject Matter 12-151-07 AIA 07-97 12-51-07 Claim s 1, 2, 5, 6, 9, 10,13, 14, 16, 17-18 & 19-20 are allowed. With respect to claims 1 & 17 , the instant claims are allowable over the prior art of record, because the prior art is silent to: a negative electrode material comprising a core and an amorphous lithium-silicon alloy layer cladding the core, the core comprising a glassy solid electrolyte and amorphous lithium-silicon alloy particles dispersed in the glassy solid electrolyte, the material of the amorphous lithium-silicon alloy particles is Li x Si, 0<x≤4.4, and the material of the amorphous lithium-silicon alloy layer is Li y Si, 0<y≤4.4. The prior art, such as Yang et al. US-20180191029-A1, teaches a negative electrode material (anode 1; [0046]) comprising, amorphous lithium-silicon alloy particles (Li 4 Si; [0046]). However, the reference does not teach a shell-core structure, wherein the core is a glassy solid electrolyte and amorphous lithium-silicon alloy particles of the formula Li x Si, 0<x≤4.4 dispersed in the glassy solid electrolyte, with a shell of amorphous lithium-silicon alloy layer is Li y Si, 0<y≤4.4. The prior art, such as LU et al. CN-109671929-A, teaches a negative electrode material (anode; Abstract) comprising, lithium silicon alloy composite negative electrode material core coated by electrolyte wherein the solid electrolyte is Li2S-P2S. See the abstract & Summary of the Invention. However, the reference does not teach a shell-core structure, wherein the core includes a glassy solid electrolyte, with a shell of amorphous lithium-silicon alloy layer is Li y Si, 0<y≤4.4. Therefore the instants claims are patentably distinct from the prior art of record. Claims 2, 5, 6, 9, 10, 13, 14, 16, 18 & 19-20 are allowable based on dependency to claims 1 & 17, respectively. 07-43-02 AIA Claim s 3-4, 7-8, 11-12, 15 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Claim Rejections - 35 USC § 112 07-30-02 AIA The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 07-34-01 Claims 3-4, 7-8, 11-12, 15 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 3-4, the term “the mass fraction of the amorphous lithium-silicon alloy particles in the core is 50%-95%” is of uncertain meaning rendering the claims vague and indefinite. A “mass fraction” is not represented by a percentage. An appropriate correction is required. Claims 7-8, 11-12, 15 are rejected based on dependency to claims 3 & 4, respectively.
