3M and Reshine Complete NMC Cathode Patent License Agreement
ST. PAUL, Minn. -- July 9, 2013
3M and China-based Hunan Reshine New Material Company, Ltd have entered into a
patent license agreement to expand the use of nickel, manganese and cobalt
(NMC) used in lithium ion batteries. These batteries provide energy to a host
of diverse applications ranging from the consumer electronics market to the
automotive market. Under the agreement, 3M grants Reshine a license to U.S.
Patents 6,660,432, 6,964,828, 7,028,128, and 8,241,791 and all global
equivalents including in Taiwan, Japan, China and Europe.
The cathode compositions composed of nickel, manganese and cobalt offer an
outstanding balance of power, energy, thermal stability and low cost. NMC
cathode materials can be tailored through changes in composition and
morphology to meet a wide range of demanding customer requirements, including
high-energy, handheld consumer electronics to high-power (hybrid) electric
vehicles. For large format battery applications, the excellent thermal
stability of NMC cathode compositions contributes to improved battery safety
performance and enables a lower total battery system cost.
“We are very pleased to have reached this agreement with 3M. It will further
expand Reshine’s product offering and pave the way for NMC cathode materials
in emerging applications for lithium ion batteries in the automotive market as
well as further penetrate the established consumer electronics market,” said
Tang Shunguo, president, Hunan Reshine New Material Company, Ltd.
“The compositions described in these patents will enable battery customers to
further reduce cost and minimize materials cost fluctuations that are typical
with higher cobalt cathode compositions,” said Christian Milker, business
manager, 3M Electronics Markets Materials Division. “This agreement with
Reshine will accelerate the market adaptation of the technology and enhance
our ability to meet the rapidly growing needs of lithium ion battery
Recently, the United States Patent and Trademark Office (USPTO) issued an Ex
Parte Reexamination Certificate for U.S. Patent 7,078,128. As a result of the
reexamination, the USPTO confirmed the patentability of all of 3M’s originally
issued claims and no amendments were made to the patent.
3M continues to build on its expertise with investment and research on a
number of product solutions and a broad-based technology portfolio targeting
lithium ion batteries including anode powders, cathode powders and electrolyte
additives. For more information about 3M Electronics Markets Materials
