SINGAPORE and TOKYO, Sept. 5,
2023 /PRNewswire/ -- Decarbonization solutions
provider noco-noco Inc. (Nasdaq: NCNC, "noco-noco") and the 3DOM
Alliance Group today announced that lithium-ion batteries equipped
with the proprietary X-SEPA™ separator and a high
temperature-resistant electrolyte have exceeded 2,000 cycles under
60°C conditions in ongoing charge-discharge cycle life testing.
The X-SEPA™ is a revolutionary separator
technology developed by the 3DOM Alliance Group that contributes to
enhanced battery lifespan and performance. noco-noco holds an
exclusive license and is working to commercialize the technology,
including in Southeast Asia where
countries are increasingly experiencing unprecedented heat.
Temperatures as high as 60°C significantly shorten the lifespans
of conventional lithium-ion batteries. To address this issue, the
3DOM Alliance Group utilizes the X-SEPA™ in
combination with a high temperature-resistant electrolyte, which
has a high boiling point, to effectively suppress electrolyte
degradation.
Previously, the integration of this electrolyte into
conventional lithium-ion batteries posed a challenge primarily due
to its high viscosity, which rendered it incompatible with
general-purpose polypropylene separators. However, it can be used
in combination with the X-SEPA™ separator due to the
X-SEPA™'s highly porous structure and strong wettability
of its polyimide material with organic electrolyte.
Interim results of ongoing charge-discharge cycle life testing
at 60°C show that batteries equipped with the X-SEPA™ and high
temperature-resistant electrolyte demonstrate significantly higher
capacity retention than batteries using a general-purpose
electrolyte and separator after 2,000 cycles. The lifespan is
extended by approximately five times when the battery end-of-life
is set at 80% capacity retention, which is common for electric
vehicle applications.
In-house testing has further confirmed that the higher boiling
point of the high temperature-resistant electrolyte drastically
reduces swelling in laminate battery cells when heated on a hot
plate over 150°C. This addresses a critical issue that arises when
battery-powered devices are exposed to high-temperature
environments.
The latest results demonstrate significant progress since
approximately 900 cycles at the time of the previous interim
results announced by 3DOM Alliance
Inc. and noco-noco in April 2023.
Technical experts from the 3DOM Alliance Group will present
details of this research at the 2023 Fall Meeting of the
Electrochemical Society of Japan
to be held at Kyushu University on
September 11 and 12, 2023.
Masataka Matsumura, CEO of
noco-noco, commented, "We are excited about these breakthroughs and
look forward to verifying the full potential of the technology as
testing progresses. We believe it will be a step change in
accelerating sustainable electrification, especially in regions
with an unmet need for batteries that can deliver higher
performance and longer life even in extremely hot weather."
