GM says China lab develops solid-state battery

BusinessAutomotiveGM says China lab develops solid-state battery
  • The Shanghai-based science lab of the automaker has engineered a “revolutionary” high-power bipolar solid-state battery that is poised to shake up the game.

General Motors has made a major breakthrough in battery technology with the development of a high-power bipolar solid-state battery from its Shanghai-based science lab. This game-changing technology offers a number of significant advantages over conventional liquid electrolyte batteries, including better thermal stability, abuse tolerance, and all-climate serviceability.

One of the key features of this new battery technology is its unique bipolar stacking and interfacial ionic booster, which results in a simplified configuration. This design leads to a 30% higher volumetric cell-to-pack ratio and a 19% reduction in pack costs compared to traditional Lithium-ion batteries. These improvements make the new battery a more cost-effective and reliable option for a wide range of applications.

The new battery will be used in 12-volt start/stop, 48-volt mild hybrid, and battery-assisted systems to store energy, making it an ideal choice for electrified vehicles. GM China has stated that this technology will “create greater commercial synergy” with Li-ion batteries for electric vehicles, and will be integrated into GM’s Ultium EV platform to provide customers with a better driving experience.

In addition to its potential impact on the electric vehicle market, GM’s high-power bipolar solid-state battery also has the potential to assist electrification in other industries such as locomotives, wind power generation, and mobile medical equipment. With its combination of thermal stability, abuse tolerance, and cost-effectiveness, this new technology has the potential to revolutionize the battery industry and change the way we power our devices and vehicles.

General Motors has always been at the forefront of innovation, and this new development in battery technology is a testament to the company’s commitment to creating cutting-edge solutions that improve the lives of people around the world. The high-power bipolar solid-state battery is a major step forward for the battery industry, and has the potential to have a far-reaching impact on a number of different industries and applications.
