The invention discloses a battery and electronic equipment. The battery comprises a battery cell and a protective circuit board, wherein the battery cell comprises a roll core and a sealing film, the sealing film wraps the roll core, and the roll core is formed by rolling a negative electrode plate layer, a first metal plate layer, a first isolating film, a positive electrode plate layer and a second isolating film together according to a circumference; the first metal plate layer and the negative electrode plate layer are used for generating voltage; and the protective circuit board is connected with the first metal plate layer and the negative electrode plate layer, and is used for acquiring voltage, determining whether the voltage is greater than or equal to a predetermined voltage threshold, and generating a response protection processing mechanism to prevent crystallization of the negative electrode plate layer when the voltage is greater than or equal to the predetermined voltage threshold.
