With its 21700 cylindrical cells, Samsung SDI propels the Lucid Air Grand Touring to the pinnacle of electric autonomy.
A world record to validate a technology
The record set by the Lucid Air Grand Touring would not have been possible without the batteries developed by Samsung SDI. Powered by 21700 cylindrical cells, the electric saloon covered 1,205 kilometres on a single charge. This record has been approved by Guinness World Records. The journey, made in July 2025 between St. Moritz in Switzerland and Munich in Germany, demonstrated the vehicle’s real-world performance. It took place in a variety of conditions, including Alpine roads, motorways and secondary networks.
High-performance cylindrical cells
The 21700 cells used by Samsung SDI represent a major advance in terms of energy capacity. As a result, they also offer extended life and rapid recharging. This format, which is larger than conventional 18650 cells, offers higher energy density while improving thermal stability. These cells enable the battery to maintain high efficiency even under prolonged loads, an essential advantage for long-distance use.
An ultra-fast recharging system
The integration of this battery into Lucid’s electric platform is based on an advanced charging architecture. Thanks to this technological synergy, the pack can recover up to 400 kilometres of range in just 16 minutes. This recharging speed, unprecedented for a production model, is made possible by the optimisation of the cells, the pack and the power electronics developed jointly by Lucid and Samsung SDI.
A long-term technological partnership
Samsung SDI and Lucid have been working together since 2016, long before the launch of the brand’s first production model. This strategic collaboration led to the development of the first Lucid Air prototypes. It then led to marketed versions, such as the Dream Edition and the Grand Touring. Together, the two companies have refined an integrated technical solution that combines efficiency, reliability and safety.
A showcase for battery innovation
With this record, Samsung SDI is showing that its technologies are not reserved for prototypes or concepts. They are being deployed in production vehicles, accessible to consumers and approved for the road. The company intends to strengthen its presence in the global high-performance battery market. It will continue to invest in R&D (research and development), while consolidating its partnership with Lucid.
