Solid-state batteries are at the forefront of battery technology, offering significant improvements in energy density, charging times, safety, and lifespan compared to traditional lithium-based batteries. Chinese automakers are taking the lead in this innovation, with IM Motors, a joint venture between China’s SAIC group, Alibaba, and Zhangjiang Hi-Tech, making bold claims about their upcoming EV, the Zhiji L6 sedan.
IM Motors took to microblogging platform Weibo to announce that the Zhiji L6 will be the world’s first mass-produced EV equipped with an ultra-fast solid-state battery. The company plans to reveal technical details at the Beijing Auto Show in April. According to their claims, the L6 will feature a 130-kilowatt-hour solid-state battery, providing a range of 621 miles based on CLTC standards, which are more optimistic than EPA figures. By EPA standards, the range would be around 400 miles.
Solid-state batteries utilize a solid electrolyte instead of the traditional liquid or gel electrolyte. This enhances safety, energy density, and longevity. Many car manufacturers and battery manufacturers, including Toyota, BYD, and CATL, are competing to develop this technology. IM Motors states that the Zhiji L6 sedan uses a patented “nano-scale electrolyte” with high ionic conductivity and high-temperature resistance. The battery’s cathode is coated with nickel, while the anode is made from a high-specific energy composite silicon carbon material.
While IM Motors’ claims sound impressive, it’s important to approach them with caution until further evidence is provided. Local regulatory filings suggest that the L6 may still utilize smaller NCM batteries with a range of 447-466 miles. However, IM Motors remains firm in their assertion that the L6 will feature the industry’s first solid-state battery.
As we await more information, it’s clear that solid-state batteries have the potential to revolutionize the EV industry. If IM Motors successfully delivers on their claims, it could signify a major breakthrough in battery technology and give China a significant advantage in the global EV market. Only time will tell if their promises become reality.
