BATTERY AND ELECTRONIC DEVICE

A battery is disclosed, including an electrode assembly and an electrolyte, where the electrode assembly includes an anode plate, a cathode plate, and a separator located between the anode plate and the cathode plate. The electrolyte includes a lithium salt and an organic solvent, the organic solvent includes a linear carboxylate compound, and a mass percentage of the linear carboxylate compound in the organic solvent is 10%-70%. The separator includes a substrate, a first coating layer, and a second coating layer, where the substrate includes a first surface and a second surface, the first surface and the second surface being back to back with each other, and the first coating layer and the second coating layer are disposed on the first surface and the second surface respectively. The first coating layer faces toward the anode plate and the second coating layer faces toward the cathode plate, the first coating layer includes a first binder and the second coating layer includes a second binder, and a median particle size of the second binder is greater than a median particle size of the first binder. The battery of this application can have both high low-temperature cycling performance and high high-temperature cycling and storage performance. This application further provides an electronic apparatus having the foregoing battery.
