A Chinese company seems to have quietly cracked the code on commercializing what it calls "semi-solid state" EV batteries, which increase the range on electric vehicles significantly.
Most EVs on the market today can travel anywhere from 200-350 miles on a single charge, but a new battery from Beijing WeLion New Energy Technology (WeLion) can go up to 621 miles, the company says. WeLion was founded in 2016 and is headquartered in Beijing. It holds a "series of core patents and technologies" and says it is the "only industrialization platform of solid-state battery technologies," according to its website(Opens in a new window).
While solid state batteries have long been dismissed as vaporware that's "always just around the corner," WeLion batteries are now available to consumers in a mass market EV: The Nio ES6.
The Nio ES6 debuted in May 2023 with a traditional lithium ion battery pack made by Contemporary Amperex Technology Co. Limited (CATL), the same Chinese company Ford is partnering with on its $3.5 billion battery plant in Michigan. As of July 2023, the ES6 is available with the upgraded WeLion "semi-solid state" battery, according(Opens in a new window) to CnEVPost and as reflected by the Nio ES6 website(Opens in a new window).
With the WeLion battery, the Nio ES6 achieves a 578-mile range, according to the Chinese version of EPA range tests (the CLTC). That's slightly less than the 621-mile max WeLion says its battery can achieve, possibly because an SUV tends to be less aerodynamic than a sedan, but it's higher than any EV sold in the US today. The ES6 is also compatible with Nio's battery-swapping program.
Nio EVs are primarily sold in China, but drivers in other regions may eventually experience WeLion's technology in vehicles from other automakers. So far, it has garnered interest from Volkswagen, Ford, Mercedes-Benz, and Geely (Volvo), the South China Morning Post reports(Opens in a new window). None have announced any vehicles with the batteries, but WeLion said this week that it plans to IPO in 2025 and increase its battery pack sales twenty-fold, Bloomberg reports(Opens in a new window).
To meet its ambitious goals, the company is building four more battery plants in China, boosting its annual capacity from 6GWh to 30GWh by 2025. In addition to EVs, WeLion offers batteries for use in medical equipment, robots, drones, and other electronic devices.
Although most new technologies tend to be expensive to produce, a WeLion YouTube video says its products are "low cost" and require "zero increase in battery cost." The Nio ES6 debuted at a relatively low $52,000 starting price with the traditional lithium ion battery, breaking Nio sales record(Opens in a new window) for a single model in a
