The secondary battery includes a negative electrode plate that includes a negative electrode film, where the negative electrode film includes a negative electrode active material; electrolyte that includes an electrolyte salt, an organic solvent and an additive, where the negative electrode active material includes a silicon-based material; the organic solvent includes dimethyl carbonate (DMC); and the additive includes one or more of compound shown in Formula 1 below, where, R1 is selected from one of C2~C4 alkylene or halogenated alkylene, C2~C4 alkenylene or halogenated alkenylene, C6∼C18 arylene and derivatives thereof. Under the premise of having a high energy density, the secondary battery and the device including the same according to the application can also have good high-temperature cycle performance and high-temperature storage performance.",
