Popis: | Hydrogen energy in the electrochemical form was studied in nickel/metal hydride (Ni/MH) battery. We have developed a Laves phase related body-centered-cubic metal hydride alloy showing a discharge capacity over 400 mAh g−1 at a 100 mA g−1 rate (C/4) suitable for electric vehicle (EV) application. The improvements in both capacity and high-rate capability were originated from the synergetic effect with a fourth phase (Ti2Ni) besides the main constituent phases of BCC, C14, and TiNi through the composition and process refinements. Together with the pouch design and advanced high-capacity core-shell β-αNi(OH)2, a prismatic cell with an energy density of 145 Wh kg−1 is designed. The simplicity in both battery and thermal management systems for Ni/MH battery EV pack provides extra advantages in both design and energy density. |
