Abstract: A negative electrode plate includes: a current collector; and a negative electrode framework located on the current collector, where the negative electrode framework includes at least a first negative electrode framework layer and a second negative electrode framework layer, the first negative electrode framework layer is located between the current collector and the second negative electrode framework layer, and a porosity of the first negative electrode framework layer is higher than a porosity of the second negative electrode framework layer. With this design, side reactions between lithium metal and an electrolyte can be reduced, formation of lithium dendrites can be inhibited, and drastic swelling and contraction of the negative electrode plate in volume due to intercalation and deintercalation of lithium ions can be greatly alleviated or even eliminated, thereby improving safety and stability of the electrochemical apparatus.
