EnerDel to Deliver Lithium-Ion Battery Samples for HEVs in June 2007

EnerDel, the lithium-ion battery subsidiary of Ener1, has received orders to deliver Li-ion battery samples based on its proprietary technology to a leading European OEM automotive company and to a leading tier-one automotive supplier.

The samples will be tested as part of programs to use Li-ion batteries in hybrid electric vehicles (HEVs). EnerDel is also in discussions with several US based OEMs and tier-one automotive suppliers for delivery of Li-ion battery samples for evaluation.

EnerDel has developed its own lithium titanate (titanium oxide) anode material in collaboration with Argonne National Laboratory (ANL) for HEV applications. The company has also developed a hard carbon anode lithium-ion battery that it will target at plug-in hybrid (PHEV) and battery electric vehicle (BEV) applications. For the cathode, EnerDel uses manganese spinel (LiMn2O4). EnerDel uses a flat prismatic cell design.

In February, EnerDel’s Li-ion cells met and exceeded phase-one performance goals of the US Advanced Battery Consortium (USABC) program contract subsidiary in testing for power-assist goal performance, including tests for static capacity, hybrid pulse power, self-discharge and thermal performance at various temperatures. (Earlier post.)

In particular, the EnerDel cells averaged 50% more discharge power (i.e., ability to accelerate in stop-and-go traffic) compared to the end-of-life target, and the cells had a significantly lower self-discharge (i.e., the amount of battery energy loss when the vehicle is not operating) than the USABC target.

The batteries are now being tested for high hybrid pulse power characterization, cold cranking, efficiency and lifetime performance.

EnerDel is working under a 12-month, cost-share contract from USABC as part of a proposed three-phase plan to launch a cost competitive lithium ion battery that is lighter, smaller and higher in power than existing battery technologies for hybrid electric vehicles.

The company is collaborating with Argonne National Laboratory on the advanced materials that give the battery its characteristics. EnerDel’s long-term plan includes the mass-manufacture of Li-ion batteries in the State of Indiana using automated production technologies.



How come we haven't heard about these guys so far. Or maybe I am not informed?


Kokobokov, You just haven't been paying attention. Or maybe all the A123 and Altair posters on this area of the GreenCarCongress site have clouded your vision :) Ener1 is very real, and if they can stay afloat financially through this development phase, they may have a shot at being a player in this space. A second more stringent round of independent lab test results on their batteries is expected in the next 1-2 months, and with it (should) will come a more lucrative Phase 2 deal with the USABC. Paid "independent" research places a $2 price target on the stock in the next 12-24 months. Read for more commentary on this stock. And good luck! All IMO.


The phrase "if they can get the funding" just kills me. We get enough seed funding to these companies so that they can go broke at some later date and then we crow about American innovation. Let us make up our minds people, if we are so proud of our innovation, then fund these efforts so that we can get some real benefits from this! The private sector venture capital route seems like all we have right now and guess what..a lot of those venture funds are using pension fund money! The heck with the middle man and just make some direct investments and let's get on with it.
