"textContent": "A positive current collector (10), a positive electrode plate (20), a battery (5), and an apparatus, the positive current collector (10) comprising a support layer (101), provided with two opposite surfaces in a thickness direction of the support layer (101), and a conductive layer (102) arranged on at least one of the two surfaces of the support layer (101), wherein the conductive layer (102) has a thickness D1 satisfying 300 nm ≤ D1 ≤ 2µm; and when the positive current collector (10) has a the tensile strain of 3.0% or more, the conductive layer (102) has a sheet resistance growth rate of T1 ≥ 50%. The positive current collector (10) has higher safety performance and meanwhile higher electrical performance, and thus a positive electrode plate (20) and a battery (5) adopting the positive current collector (10) could have higher safety performance and meanwhile higher electro-chemical performance.",
