      GAIA High-Power Lithium-ion Battery Outpaces Ultracapacitors

      Lithium Technology Corp. has released that the PennState University Future
      Truck Team, using one of its GAIA brand Hybrid Electric Vehicle (HEV)
      batteries, placed second in the 2004 Future Truck Competition, held at Ford
      Motor Company's Michigan Proving Ground and Allen Park Test Laboratory near
      Detroit June 9-17, 2004.

      The vehicles in this engineering competition had to display both performance
      and endurance in the nine-day event. In addition to a variety of braking,
      handling, safety and emission tests, they had to demonstrate a high degree
      of off-road mobility and tow a one-ton trailer up a steep 15-mile grade. The
      competition culminated with an 80-mile on-road course at the Michigan
      Proving Ground, including a 30-mile high-speed run, an acceleration contest
      and a fuel economy trial.

      PennState's SUV was equipped with a 5 Kilowatt-hour, 180-Volt HEV lithium-
      ion battery provided by LTC. (See LTC news release of July 8, 2003) This
      high-power battery delivered more than 50 Kilowatts of power for
      acceleration and reclaimed more than 35 Kilowatts of regenerative braking
      power, which greatly contributed to the PennState Team's high point
      standing. The PennState Team took second place overall, which merited an
      award of $5000, and also won 'best entry' in three separate technical and
      competitive categories. In addition, PennState's Dr. Daniel Haworth won the
      prestigious National Science Foundation Outstanding Faculty Advisor award,
      which included a $20,000 engineering grant to the advisor's university.

      Ryan Harrier, the PennState team's stored energy expert, attributed a large
      degree of the team's success to the GAIA lithium-ion battery system. "The
      GAIA lithium-ion battery and a modification of the control strategy allowed
      us to reach about 23MPG on-road fuel efficiency," said Mr. Harrier. "This
      was a 37 percent improvement over last year's lead acid battery and a 21
      percent improvement over the stock Ford Explorer." At least half of these
      improvements resulted by changing from a lead acid to a lithium-ion battery,
      according to Mr. Harrier. The high rate capability of LTC's GAIA battery was
      an outstanding asset for PennState, outpacing competitors' strategies. Along
      these lines, Mr. Harrier added, "I talked to the team using Maxwell
      ultracapacitors as energy storage, which we had actually considered at one
      point last summer for our energy storage, and even they could not recapture
      200 Amps (35 Kilowatts) of regenerative braking power that the GAIA battery

      The battery also contributed competition points for design. Using the
      compact GAIA lithium-ion battery permitted the team to collocate it with all
      the other high-voltage components in a single enclosure. According to Mr.
      Harrier, this resulted in a clean and safe electric power package which
      swayed the judges to award the PennState team prizes for "best workmanship"
      and best overall design ("vehicle design inspection).
