NIO, a prominent electric vehicle manufacturer in China, has recently completed a remarkable range test for their latest 150 kWh semi-solid-state electrolyte battery pack. This test, performed in real-world conditions, achieved an impressive 652.5 miles (1044 km) on a single charge, setting a new benchmark in EV battery performance. NIO's CEO William Li personally took the wheel for this test, which was live-streamed to demonstrate the battery's capabilities.
