GM battery research in China leading to affordable electric cars
With all the uproar over Wanxiang's rescue of A123 Systems, there's another piece of battery manufacturing news in China that is worth considering. GM China has begun manufacturing prototype battery cells at its Advanced Technical Center in Shanghai. The move enables GM researchers to work on developing next generation vehicle battery systems, but also underscores the size of GM's operations in China and that company's collaboration with SAIC, one of China's largest automakers. The work at this center also validates recent statements by GM's CEO Dan Akerson over longer range electric cars.
In December 2011, GM announced the Advanced Technical Center, then under construction, would be ready to begin full operations in July 2012. The ATC first opened in September 2011, as one of GM's network of technical centers around the world. The company described the ATC as "the most comprehensive advanced automotive technology development center in China." Researchers at the ATC will work with the Pan Asia Technical Automotive Center (PATAC), an already existing facility jointly owned by GM and SAIC, and the ATC will contain these labs: China Science Lab, Vehicle Engineering Lab, Advanced Powertrain Engineering Lab and Advanced Design Center.
The first phase of the ATC's construction was the Advanced Materials Laboratory Building, which included a battery cell testing lab, battery material lab, metallography and electrochemical lab, cell fabrication lab, and micro-foundry and formability lab. Researchers at this lab are able to do battery material preparation, battery material coating, battery cell fabrication and battery cell performance testing.
Production of the first batch of battery cells at the ATC, using state-of-the-art fabrication methods, is an important milestone in the establishment of its battery material assessment capability. With "battery material assessment," the company's researchers will be able to test and validate advanced materials provided by suppliers, apply innovative technologies to battery cell design and fabrication through collaboration with cell suppliers, and finally design complete battery systems for integration into plug-in vehicles.
“Producing the first prototype battery cells is a big step forward for the GM China Advanced Technical Center. It is critical for enabling GM to develop smaller, lighter and lower-cost new-generation batteries,” said John Du, Director of GM China’s China Science Lab. “Leveraging this success, the independent assessment system for battery materials will help speed up technical progress.”
