Novel silicon-dominant composite anode technology enables high energy density Li-ion batteries
IRVINE, Calif. - Tuesday, December 9th 2014 [ME NewsWire]
(BUSINESS
WIRE) - Enevate Corporation, a leading developer of advanced
rechargeable Lithium-ion (Li-ion) batteries, announces HD-Energy®
Technology for Li-ion batteries. Enevate’s HD-Energy Technology enables
high energy density rechargeable Li-ion polymer cells using a novel
silicon-dominant composite anode that has four times the energy density
of conventional graphite anodes.
Enevate Corporation, based in
Irvine, California, is focused on delivering advanced Li-ion batteries
into smartphones, tablets, ultra-thin/hybrid notebook PCs, and wearable
devices, delivering significantly higher energy density in thinner form
factors to enable longer runtimes in less space.
“Enevate is using a
unique technical approach for silicon anodes that is truly different and
innovative to deliver high energy density Li-ion batteries,” said Dr.
John Goodenough, recipient of the US National Medal of Science who
helped invent the Li-ion battery, and Professor of Material Science at
University of Texas-Austin. “I’m impressed that their technology and
process is practical, highly manufacturable, and can be sufficiently
inexpensive for high volume consumer electronics.”
Developed from
several years of original research work, Enevate’s novel HD-Energy
Technology utilizes silicon-dominant composite anodes for rechargeable
Li-ion polymer batteries which dramatically increase energy density over
conventional graphite anode cells. While conventional graphite anodes
can store 372 mAh/g, pure silicon through an alloying process has the
potential to store up to 4200 mAh/g. The self-standing, flexible, and
conductive anodes are comprised of majority silicon in a complex
micromatrix composite that is 100% active and contains no inactive or
“dead space” binders and is engineered for high volume manufacturing.
The HD-Energy Technology delivers a high capacity monolithic or
“single-particle” anode which enables cell designs today up to 700-800
Wh/L core energy density with cycle life similar to graphite cells.
Competitive approaches using silicon nanowires or nanoparticles are
difficult and expensive to manufacture in high volume. Others using
silicon oxide (SiO) as a dilute additive in graphite anodes do not
deliver enough performance improvement.
“We have developed very high
energy density Li-ion cells for mass production with our new HD-Energy
Technology utilizing silicon-dominant anodes,” said Dr. Benjamin Park,
CTO of Enevate. “This new and different approach allows us to realize a
roadmap to over 1000 Wh/L volumetric energy density which is very
exciting to differentiate mobile consumer applications.”
“Imagine
what can be achieved with four times the energy density in smartphones
and other mobile devices,” said Jarvis Tou, Executive Vice President of
Marketing and Products at Enevate. “A sleek product design with a
significant increase in energy creates opportunities for
energy-intensive features like new software capabilities, better
displays, always-on sensors, improved cameras, faster connectivity, and
increased performance.”
Enevate’s custom cell designs using HD-Energy
Technology also have very low AC impedance or internal resistance,
typically less than half that of graphite cells. Utilizing available
cathodes, separators, and electrolytes in today’s Li-ion ecosystem,
Enevate’s Li-ion batteries are designed to meet UN, UL, and CTIA safety
certifications. Enevate’s HD-Energy Technology delivers combined
attributes ideal for use in sleek mobile devices to deliver more
runtime, enable new energy-hungry features, and allow for thinner
product designs.
