Stratus Materials Inc., a company focused on the development and
commercialization of advanced cathode active materials (CAMs) for
lithium-ion batteries, today announced that its first-generation
LXMO CAM material has achieved a significant milestone associated
with cycling durability in electric vehicle applications.
This month, LXMO-containing pouch cells surpassed 1,000 full
depth-of-discharge cycles while maintaining greater than 80% of
their initial capacity, a common goal across the EV battery
industry. The 3rd party-built cells used standard cell and
electrode designs, employing a natural graphite anode and an
electrolyte of standard industry components, to work in conjunction
with the Stratus cathode material. The cells in the test group
maintained 82-86% of their initial capacity and are projected to
exceed 1,200 cycles before reaching 80% of their initial
capacities. At the same 1,000-cycle point, the average discharge
voltage of the cells maintained approximately 97%, dropping only
0.1 V from their initial values. The excellent capacity and voltage
stability of the cells surpass the energy retention of many
commercial materials in use today.
Jay Whitacre, CEO & CTO of Stratus Materials (and Professor
at Carnegie Mellon University), said: “These cells have been
cycling for the last 10 months and clearly demonstrate that our
proprietary materials are able to meet EV industry durability
needs. To our knowledge this is the first time such minimal loss in
cell voltage has been documented for this class of materials. The
Stratus team looks forward to building upon these strong technical
results as we improve, commercialize, and scale production in the
coming quarters.”
Stratus products are in the lithium-rich, manganese-rich (LMR)
category of cathode active materials. LMR cathodes have garnered
significant interest in the Li-ion battery and EV industries due to
several highly promising attributes including high energy density,
low cost, and high safety. However, despite being in development
around the world for over two decades, LMRs have not yet been
commercially deployed because of several persistent technical
challenges – primarily the voltage and capacity instability issues
that Stratus Materials has largely overcome, as demonstrated by its
latest results. With its continued technological progress, Stratus
Materials is focused on enabling the first fully functional,
LMR-class CAMs that are suitable for full-scale, commercial
use.
Scott Pearson, President & CCO, added: “We are thrilled to
show that our first-generation LXMO material can exceed this EV
cell durability target while also delivering a set of highly
compelling advantages versus incumbent CAMs. We expect that this
proof point will be one of many that we will be offering to our
industry partners and customers.”
Stratus is currently producing materials on its existing
pre-pilot production line in Pittsburgh, Pennsylvania and has
ongoing sampling efforts underway with many of the leading
companies in the EV and EV battery industries. As previously
announced, the company will be increasing its production
capabilities from pre-pilot to pilot scale later in 2024.
