Lithium Technology Corporation (LTC), a global provider of large, rechargeable lithium-ion power solutions, is developing two of the largest, highest capacity lithium-ion battery systems yet for plug-in hybrid automobiles and non-nuclear submarines.
In conjunction with an unnamed automaker, LTC is developing a 12 kWh Li-ion battery system that should support a plug-in hybrid application in a four-passenger vehicle with an all-electric range of 60 miles. LTC says that its Li-ion system will be comparably sized to existing battery packs of about half the capacity.
In a joint venture with ThyssenKrupp, LTC’s subsidiary GAIA Akkumulatorrenwerke (GAIA) is in development of a battery system for the ThyssenKrupp’s non-nuclear submarine. This battery system will enable propulsion four times longer and safer than lead-acid powered vessels.
Conventional submarines contain lead-acid batteries which emit hydrogen-oxygen gases that can cause explosion during operation. The lithium-ion battery is hermetically sealed, making it safer transport for the passengers aboard. While it will be the largest lithium-ion battery solution in the world, the system utilizes less than one-third of the space the standard lead-acid battery consumed, allowing more vessel space for other applications. LTC estimates a delivery date of the first quarter of 2008.

Lithium Technology Corporation (LTC) provides large format rechargeable power solutions for diverse applications in the military and national security systems, transportation and stationary power markets.
LTC manufactures the GAIA product line of large, high-power hermetically sealed rechargeable lithium-ion cells and batteries. The GAIA cells and batteries are either designed to maximize energy content (HE product line) or power capability (HP or UHP product lines).
Earlier this year, LTC announced that it had provided three 2.2 kWh Li-ion batteries to Zytek Systems in the UK for the development of a hybrid vehicle as part of the Energy Saving Trust’s Ultra-Low Carbon Car Challenge (ULCCC).
The vehicle is based on a smart forfour and will utilize a hybrid power train based on 1500cc, 3-cylinder turbo charged diesel engine coupled to 2 high-efficiency permanent-magnet electric motors.
The batteries can be charged by either the ICE, by regenerative breaking, or by the grid (plug-in hybrid), and will have a modest all-electric range.
Zytek is also the developer of the all-electric smart fortwo recently introduced into the UK by DaimlerChrysler. That vehicle uses a Zebra Sodium Nickel Chloride battery. (Earlier post.)
