EnerDel and Fisker, the independent American carmaker developing a line of plug-in vehicles for the global market, have signed a letter of intent for a potential long-term battery supply agreement. Results of reliability and performance testing will determine a final contract. The Fisker Karma is scheduled to be the first OEM plug-in hybrid electric vehicle (PHEV) on the US market in June 2010.
Fisker currently plans to build 15,000 vehicles per year and market them through an existing network of 32 US retailers. A European retail network will be announced in September at the Frankfurt Motor Show in Germany.
Fisker had earlier said it would use lithium-ion batteries developed by Quantum’s strategic alliance partner Advanced Lithium Power Ltd. (ALP) (Earlier post.)
EnerDel currently produces two primary types of Li-ion cells:
High power cells targeted at hybrids, using a Lithium Titanium Oxide (LTO)/Lithium Manganese Oxide (LMO) chemistry. The LTO/LMO combination is a very safe and long lasting chemistry, with more than 100C pulse power capability and excellent cold cranking capabilities. The cells have a lower energy density and lower cell voltage compared to cells with a graphite anode.
EnerDel is producing both a 1.8 Ah CD-size cell (3.6V) and a 5 Ah A5-size cell (3.6V).
High energy cells, targeted at plug-ins and EVs, using a Hard (Amorphous) Carbon (HC)/mixed oxide (NMC) chemistry. Nominal capacity of the cells is 20 Ah, at a nominal voltage of 3.7V. (max voltage is 4.2V, min is 2.7V). The stacked electrode design enables an energy density of more than 150 kWh/kg.
The announcement came in conjunction with EnerDel’s commissioning of the US’ first commercial-scale production line for lithium-ion automotive battery packs at its plant in Indiana on Friday. EnerDel plans to expand both cell manufacturing capacity at the Indianapolis plant and pack assembly capacity at the company’s Noblesville facility. Further expansion is under consideration through purchase or construction of a third factory.
Future anticipated annual production capacity would involve creating the ability to produce up to 1,500,000 hybrid packs, or 600,000 plug-in hybrid systems, or 150,000 packs for pure electrics, or some combination thereof depending upon the company’s customer portfolio. EnerDel expects to employee a total of 3,000 people once full target capacity is achieved.
Separately, Khalil Amine, Ilias Belharouak and Zonghai Chen at the US Department of Energy’s (DOE) Argonne National Laboratory won an Excellence in Technology Transfer Award for their development of the LTO system, which was transferred to EnerDel.
When combined with a lithium manganese spinel, LTO provides the highest power ever reported in a Li-ion battery, excellent cycle-life and unmatched safety performance when compared with other Li-ion battery technologies. Moreover, a battery based on this system won’t overheat during high-rate cycling and easily achieves 5-kilowatt cold cranking at minus-30 degrees Celsius.—Dr. Khalil Amine
Essential for the transfer of technology to EnerDel was Argonne researchers’ ability to meet the company’s commercialization goals within the unprecedented time span of only one year, said Jeff Chamberlain, a senior account manager in Argonne's Office of Technology Transfer. “The market realities facing EnerDel when it decided to work with Argonne were such that if it could not commercialize a Li-ion battery within two years, it might as well not bother since the market opportunities could have evaporated due to domination of the emerging marketplace by established HEV battery makers and their new Li-on battery offerings.”
Argonne worked with EnerDel to develop the technology under a Work-for-Others agreement. The DOE Vehicle Technologies Program provides funding for battery research and development at Argonne.
