摘要： In a cell and an electronic device, a first positive electrode film and a second positive electrode film are respectively arranged on two opposite surfaces of a positive electrode current collector. A gram capacity of a second positive electrode active substance is greater than a gram capacity of a first positive electrode active substance. A first negative electrode film and a second negative electrode film are arranged on two opposite surfaces of a negative electrode current collector. OI2−OI1>5, where OI2 is an OI value of the second negative electrode film, and OI1 is an OI value of the first negative electrode film. The positive electrode and the negative electrode in the cell are reasonably matched, which can maximize total energy density and capacity of the cell while also taking safety into account.

The negative electrode includes a negative electrode material layer. The negative electrode material layer includes a binder. The binder includes a first binder and a second binder, where the first binder is selected from styrene-butadiene rubber polymers and the second binder is selected from polyacrylic acid polymers. A weight-average molecular weight of the first binder is 40,000 to 300,000, and a weight-average molecular weight of the second binder is 400,000 to 2,000,000. A mass percentage of the first binder is 10% to 90% based on a mass of the binder.
