Rechargeable lithium ion cells offer significant improvements in energy density, specific energy and cycle life compared with Cd Ni cells and H 2 Ni cells for future space missions. Shanghai Institute of Space Power sources has developed prismatic lithium ion cells of 6, 12, 30 and 50 Ah for aerospace applications. Using advanced technology and high energy materials, 6, 12, 30 and 50 Ah cells with specific energy of 106, 113, 134 and 130 Wh/kg and energy density of 232 , 258, 335 and 308 Wh/L have been manufactured respectively. Discharge rate up to 0.5 C and 100% DOD, life cycling to greater than 200 cycles have been achieved. These prismatic lithium ion cells also have been demonstrated to operate effectively at high discharge rate up to 1.7 C and at temperature as low as -10 ℃.
