A Look Inside SLAC’s Battery Lab

leave a comment »

In this video, Stanford materials science and engineering graduate student Zhi Wei Seh shows how he prepares battery materials in SLAC’s energy storage laboratory, assembles dime-sized prototype “coin cells” and then tests them to see how many charge-discharge cycles they can endure without losing their ability to hold a charge. Results to date have already set records: After 1,000 cycles, they retain 70 percent of their original charge.
