BATTERY GOALS
Midterm goalc -- -- 5 600 <$150 80-100 135
Long-term goald -- -- 10 1,000 <$100 200 300
CURRENT STATUS
Nickel-cadmium Available 65-140 8 700-1,200 $300-$500 45-55 100-150
Lead-acid Available 50-70 2-3 300-400 $150-$200 35-40 100-130
Nickel-metal hydride Available 100-120 8 700-1,200 $300-$700 High 60s-70s 150-200
Lithium-ion or lithium-polymer 1-4 150-300 5-10 400-1,200 $150-$220 100-150 100-200

a USABC did not set range goals. Range depends on vehicle and battery size. b Number of discharges in battery lifetime.
c Goals approximately for 1998. d Goals for beyond 2000.
