With regard to Claim 1 , Sugita et al. disclose in Figures 1-2, a current collector for a rechargeable lithium battery (10) , comprising: a substrate , called a positive electrode current collector (30) ; and a functional layer , called an intermediate layer (32), on the substrate (30) (paragraphs 0020-0022) , wherein the functional layer (32) includes a flame retardant, a conductive material, and a binder (paragraphs 0026-0027) . With regard to Claim 2 , Sugita et al. disclose in Figures 1-2, wherein the flame retardant includes a nitrogen-based flame retardant, a phosphorus based flame retardant, or a combination th ereof (paragraph 0031) . With regard to Claim 3 , Sugita et al. disclose in Figures 1-2, wherein the nitrogen-based flame retardant includes melamine, melamine polyphosphate (MPP), melamine cyanurate, a melamine-based copolymer, melamine sulfate, melamine pyrophosphate, melamine borate or a combination thereof (paragraph 0031) . With regard to Claim 4 , Sugita et al. disclose in Figures 1-2, wherein the flame retardant is included in an amount of 5% to 70% by weight (paragraph 0032), which meets the claimed limitation of about 50 to about 90 wt% based on a total amount of the functional layer (32) (paragraph 0032). With regard to Claim 5 , Sugita et al. disclose in Figures 1-2, wherein the conductive material is included in an amount of 1% to 20% by weight (paragraph 0034), which meets the claimed limitation of an amount of greater than about 0 wt% and less than or equal to about 30 wt%. With regard to Claim 6 , Sugita et al. disclose in Figures 1-2, wherein the binder is included in an amount of 0.1% to 10% by weight (paragraph 0035), which meets the claimed limitation of greater than about 0 wt% and less than or equal to about 30 wt%. With regard to Claim 7 , Sugita et al. disclose in Figures 1-2, wherein a weight ratio of a content of the flame retardant; and a sum of the contents of the conductive material and the binder is about 50:50 to about 90:10 (paragraphs 0032-0035) . With regard to Claim 8 , Sugita et al. disclose in Figures 1-2, wherein the functional layer (32) has a thickness of about 1 µm to about 5 µm (paragraph 0028) . With regard to Claim 9 , Sugita et al. disclose in Figures 1-2, wherein a ratio of a thickness of the functional layer (32) (1% to 10% by weight) ; and a thickness of the substrate (30) (10% to 50% by weight) is about 1:10 to about 2.5:10 (paragraphs 0022, 0028) . With regard to Claim 1 0 , Sugita et al. disclose in Figures 1-2, a n electrode , called a positive electrode (11), comprising: a current collector , called a positive electrode current collector (30) , and an electrode active material layer , called positive electrode mix layers (31), on at least one surface of the current collector (30) ; and wherein: the current collector includes a substrate (30) and a functional layer , called an intermediate layer (32), between the substrate (30) and the electrode active material layer (31) , and the functional layer (32) includes a flame retardant, a conductive material, and a binder (paragraphs 0020-0027) .
