      Energy Conversion Devices, Inc., a Delaware corporation, submits the

Item 5.  Other Events
- -------  ------------

      On July 7, 2004, Energy Conversion Devices, Inc. (ECD) announced the
settlement of patent infringement disputes and counterclaims involving nickel
metal hydride (NiMH) batteries. Attached hereto as Exhibit 99.1 is a copy of the
press release issued by ECD on July 7, 2004.

Background
- ----------

      In March 2001, ECD and its subsidiary Ovonic Battery Company, Inc. (Ovonic
Battery) initiated litigation in Federal District Court for the Eastern District
of Michigan against Matsushita Electric Industrial Co., Ltd. and related
companies (MEI), Panasonic EV Energy Co., Ltd. (PEVE), and Toyota Motor
Corporation and related companies (Toyota) for infringement of certain of Ovonic
Battery's NiMH patents in connection with hybrid electric vehicle battery and
consumer battery sales in the United States. In October 2001, Cobasys LLC (f/k/a
Texaco Ovonic Battery Systems LLC) (Cobasys), the 50/50 battery manufacturing
joint venture between ECD's Ovonic Battery and ChevronTexaco Technology
Ventures LLC (ChevronTexaco), joined the litigation as a co-plaintiff.

      In December 2001, ECD, Ovonic Battery and Cobasys filed an arbitration
demand with the International Chamber of Commerce on the claims held to be
arbitrable by the Federal District Court as well as additional patent
infringement claims. Also in December 2001, the parties initiated settlement
discussion and, in January 2002, the Federal District Court granted a joint
motion to stay further proceedings in the litigation pending the outcome of
settlement discussions. The International Chamber of Commerce also agreed to
hold its proceedings in abeyance pending settlement discussions.

      In December 2002, ECD, Ovonic Battery and Cobasys entered into an
arbitration agreement with MEI, PEVE and Toyota, which established the basic
terms, conditions and procedures to resume arbitration of the dispute before the
International Chamber of Commerce. Pursuant to the arbitration agreement, the
parties agreed to dismiss the patent infringement litigation in the Federal
District Court.

      The arbitration proceeding was held in New York City and began in November
2003 and concluded in January 2004. Since the conclusion of the arbitration
proceedings, the parties have been engaged in discussions aimed at settlement of
the disputes.

The Settlement
- --------------

      Under the terms of the settlement, ECD, Ovonic Battery, Cobasys and MEI,
PEVE, Toyota have entered into an agreement pursuant to which the parties have
cross-licensed current and future patents related to NiMH batteries filed
through December 31, 2014, effective upon the date of settlement. The licenses
granted by ECD, Ovonic Battery and Cobasys do not grant rights to MEI, PEVE or
Toyota to use the licensed patents to (i) offer for sale certain NiMH batteries
for certain transportation applications in North America until after June 30,
2007 or (ii) sell commercial quantities of certain transportation and certain
stationary power NiMH batteries in North America until after June 30, 2010.


                                     2



      Further, under the terms of the settlement, Cobasys and PEVE have agreed
to a technical cooperation arrangement, including access to suppliers, to
advance the state-of-the-art of NiMH batteries, which are widely used in hybrid
electric vehicles (HEVs). Cobasys and PEVE have also agreed to collaborate on
the development of next-generation high-performance NiMH batteries for HEVs. In
addition to manufacturing their own line of NiMH batteries, Cobasys will be the
distributor of PEVE's NiMH batteries to certain markets in North America
through June 30, 2010.

Payments
- --------

      ECD and Ovonic Battery will receive a non-refundable patent license fee of
$10 million in consideration of the licenses granted to MEI/PEVE with respect to
NiMH batteries for consumer applications.

      Cobasys will receive a non-refundable patent license fee of $20 million in
consideration of the licenses granted to MEI/PEVE and Toyota, of which $4
million will be placed in escrow to be used to pay PEVE upon reaching certain
milestones under the next-generation high-performance NiMH battery module
development project plan. Cobasys will, upon the receipt of the funds, pay
Ovonic Battery $8 million and pay ChevronTexaco $8 million as partial
reimbursement of legal expenses.

      Cobasys will also receive royalties through December 31, 2013, on certain
NiMH batteries sold by MEI/PEVE in North America.
