High Performance NiMH Battery PI: Dr. Kwo Young, Chief Scientist, - PowerPoint PPT Presentation

TEAM High Performance NiMH Battery PI: Dr. Kwo Young, Chief Scientist, BASF 248.293.7000 | kwo.young@basf.com Collaboration: Dr. Ng (WSU), Dr. Benderski Technology Overview (NIST), Mr. James (SAI) - Development of next generation NiMH battery technology with lower cost and Current Status higher energy density maintaining same (1) STATUS: anode achieved 376 mAh/g at C/3 rate; safety and life performance cathode achieved 330 mAh/g at C/10 rate (2) NEXT TECHNICAL: cycle stability and wider voltage window (3) HELP NEEDED: Electrolyte with better SEI for higher reaction current Project Statistics Award Amount $4.0M Feb. 2014 – Feb. 2016 Award Timeline Next Stage Target 400 mAh/g anode for 100 cycles Partners Sought Electrolyte Developer

 In 1999, GM EV1 equipped with NiMH battery demonstrated a range of 180 miles between charges.  Since then, battery cost structure, power performance, and cycle life have been substantially improved, but the range has not.  High capacity anode materials are developed but sensitive to electrolyte corrosion.  Therefore, continuing research in innovative electrolyte, high- voltage cathode, and high-capacity anode in NiMH is conduct in the program. 2
