     Large capacity Li-ion batteries have become a promising candidate for electric
        vehicles replacing Lead-acid batteries. Why?
 
 
 
     Excellent track record: Powernote being adopted by some Japanese LEVs . Why?
Large capacity & High energy density Less number of cell connections & Less weight
Long cycle-life : Over 3500 cycles vs. Over 500 cycles
Superior reliability and safety (Conforming to UL and UN DOT standard)
    - Mechanical durability under severe vibration and shock Metal case
    - High level of safety Notch-type safety vent
Small heating during high current discharge Uniformity in temperature both inside the cell
    and between cells in a multi-cell module Slow & uniform degradation in cell performance
