Zusammenfassung:	A lithium ion battery and an electric vehicle with the same are provided. The lithium ion battery includes a cover plate assembly 1 and a battery cell assembly 2, the cover plate assembly 1 includes a pole 10 and a polarity connecting piece 19, the pole 10 is connected with the polarity connecting piece 19, the battery cell assembly 2 is provided with a battery cell tab assembly 200, and the pole 10 is connected and conducted with the battery cell tab assembly 200 through the polarity connecting piece 19. As a hard connection, the polarity connecting piece 19 is directly or indirectly connected with the battery cell tab assembly 200. The polarity connecting piece 19 is in interference fit with the pole 10 for laser welding, so that the connection reliability is high, the overcurrent capability is strong, and electronic conduction is easy.
