Explore the Revolutionary Processes and
Exclusive Technologies Behind Lithium Ceramic Batteries
TAOYUAN, June 21, 2024
/PRNewswire/ -- ProLogium Technology, the pioneer in mass-producing
lithium ceramic batteries, has released a video showcasing its
cutting-edge giga-level factory in Guanyin District, Taoyuan. This
facility, which started operations in January, marks a significant
milestone as ProLogium transitions to full-scale production. In
2024, the factory, known as the Taoke plant, will start delivering
C-samples to global automotive clients.
ProLogium has revolutionized the lithium-ion battery industry by
replacing the traditional polymer separator film with a ceramic
separator, overcoming the inherent limitations of conventional
battery structures. This innovation led to a new battery
architecture where two substrates sandwich the cathode, ceramic
separator, and anode, supported by ProLogium's exclusive Logithium™
technology, achieving capabilities unattainable by traditional
batteries. This revolutionary architecture can accommodate more
chemical systems and materials, enhancing the battery's energy
densities. It enables fast charging from 5% to 60% in 5 minutes,
translating to a range of 300-400 kilometers while maintaining a
long cycle life. This achievement is unmatched to date,
establishing ProLogium's leading position in the industry and
challenging the preconceived notion that next-generation batteries
are "expensive" and difficult to "mass-produce".
Simple is best. ProLogium has managed to streamline the 17
core battery processes down to 13.
With ProLogium's revolutionary battery architecture and
exclusive process technologies, the core production steps for
lithium ceramic batteries have been streamlined from the
traditional 17 steps to just 13. This reduction particularly omits
the most time-consuming back-end assembly processes, such as
separator film placement, electrolyte injection, vacuum soaking,
and degassing. This one-stop, automated production line creates
commercially competitive next-generation batteries for the
market.
ProLogium's Exclusive Process Technologies Enhance Battery
Production Efficiency
Regarding electrode manufacturing, ProLogium's use of a
solid-state ceramic separator allows for processing multiple
electrodes simultaneously, unlike traditional battery production,
which uses polymer separator films and processes only one piece at
a time. ProLogium's exclusive coating process enables efficient
roll-to-roll operation with automatic roll changeover. This special
coating process, which applies the ceramic separator directly to
the anode, eliminates the need for a separator film placement step.
Compared to its first-generation technology, ProLogium's current
machinery boasts a 2.6-fold increase in width and a 2.1-fold
increase in operating length, significantly boosting productivity.
The production line speed is over four times that of the previous
generation, overcoming a major technical limitation faced by
traditional battery production. Additionally, ProLogium has
co-developed a specialized oven with its partner, specifically
designed for lithium ceramic batteries. This proprietary design
facilitates rapid drying of the electrodes, enhancing production
efficiency for next-generation batteries.
Following electrode manufacturing is ProLogium's exclusive "hot
flow dehydration" process. This technique enables rapid dehydration
at 200 degrees Celsius during the roll winding process, completing
the task in just 8 minutes. In contrast, traditional battery
processes require 8 hours for dehydration through "vacuum drying."
This significantly enhances production efficiency.
ProLogium's groundbreaking "Electrode Assembly to Form an Inlay"
technology allows for the simultaneous alignment and attachment of
12 cathode and anode electrodes through a single hot press. This
method, applying high temperature and pressure, reduces interface
resistance and improves electrical performance. This advancement
significantly increases production speed and capacity for
next-generation batteries, setting ProLogium's lithium ceramic
batteries apart from traditional ones, which can only attach one
piece at a time due to material thermal limitations.
Overcoming the Most Challenging "Multilayer Yield" Hurdle:
The One and Only Logithium™ Printer at ProLogium
Achieving high yield rates from single-layer to multilayer
production is the final hurdle in mass-producing next-generation
batteries, often requiring years to master. ProLogium holds over
800 patents, with hundreds focused on enhancing yield, spanning
cell structure to process design. At the forefront is the
Logithium™ printer, unique to ProLogium. This patented technology
ensures precise alignment and attachment during manufacturing, also
serving as a moisture barrier to prevent short circuits. It has
achieved single-layer yields of 99.9% and multilayer yields of 94%
on the pilot line. Additionally, ProLogium employs other exclusive
processes such as film laminators and flexo printing machines, both
absent in traditional battery manufacturing. Along with over 4,000
quality checkpoints and automatic inspection equipment, these
processes ensure higher yield and optimal quality.
"A new era has begun," said Vincent
Yang, founder and chairman of ProLogium. "ProLogium's
lithium ceramic batteries are setting the stage for the next 30
years in the battery industry. Our innovative battery architecture
increases energy density and enables fast charging in just 5
minutes. Remarkably, after 800 deep cycles, the battery retains 80%
of its capacity. Our Taoke factory demonstrates our ability to lead
in mass production, serving as a prototype for future expansion. We
will continue to advance our product and manufacturing
technologies, committed to driving a more sustainable and efficient
energy transition across industries. Through our technological
prowess, we will continue to showcase Taiwan's capabilities to the world!"
