Revolutionizing the EV industry, Nio proudly unveiled its groundbreaking 150kWh solid-state battery pack in July 2023, ushering in a new era of extended range and heightened energy density for their vehicles. Partnering with WeLion for this cutting-edge technology, Nio is set to introduce the revolutionary battery pack in their upcoming ES6 SUV, allowing Chinese customers to opt for this high-energy option as soon as this month.
Initially projected to offer an astounding range of 620 miles (1,000 km) on a single charge, the current range stands at a commendable 578 miles, still surpassing industry standards. Despite facing challenges and uncertainties, Nio has wholeheartedly committed to integrating solid-state batteries into its EV lineup. In May, the company took a significant stride by submitting a filing to China’s Ministry of Industry and Information Technology, outlining their ambitious plans to equip three existing EV models with the cutting-edge battery capabilities provided by solid-state battery developer WeLion.
Comparing the solid-state pack to Nio's existing 100 kWh lithium-ion pack, it boasts a slightly higher weight of 575 kg (1,268 pounds). However, what sets it apart is the remarkable energy density of 261 Wh/kg, outshining the lithium-ion pack's 180 Wh/kg by an impressive margin. This leap in energy density marks a significant stride towards more efficient and long-range electric vehicles.
