Explore the Revolutionary Processes and Exclusive
Technologies Behind Lithium Ceramic Batteries
TAOYUAN, June 20,
2024 /PRNewswire/ -- ProLogium Technology, the first
to mass-produce lithium ceramic batteries and a leader in
next-generation battery technology, has released a video
highlighting its first giga-level factory for lithium ceramic
batteries in Guanyin District, Taoyuan. This video showcases
ProLogium's state-of-the-art battery manufacturing processes and
exclusive patented technologies at this facility, which was
inaugurated in January. This significant milestone demonstrates
ProLogium's success in transitioning from pilot-scale to full-scale
production, proving their capability to mass-produce lithium
ceramic batteries. In 2024, they are ready to deliver C-samples to
global automotive industry clients from this brand-new facility in
Taoyuan, commonly known as the Taoke plant.
ProLogium has disrupted the technology in the lithium-ion
battery industry, which has been adopted for over 30 years, by
replacing the traditional polymer separator film with a ceramic
separator. This breakthrough has overcome the inherent limitations
of the old lithium-ion battery structure and led to the development
of an innovative battery architecture with two substrates
"sandwiching" the cathode, ceramic separator, and anode, supported
by ProLogium's exclusive Logithium™ technology on the sides. This
revolutionary architecture can accommodate more chemical systems
and materials, enhancing the battery's energy densities. It also
enables fast charging from 5% to 60% in just 5 minutes, translating
to a range of 300 to 400 kilometers while maintaining a long cycle
life under such conditions. This new architecture creates a
paradigm in which performance and energy density are achieved
without trade-off, and supports mass production with streamlined
processes, higher efficiency, greater capacity, and improved yield,
significantly reducing manufacturing costs. This directly
challenges the market's long-standing perception that
next-generation batteries are "unable to be mass-produced" and
"expensive."
Simple is best. While it's not easy to achieve simplicity,
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.
Faster Production, Higher Output: ProLogium Achieves Greater
Efficiency with Exclusive Process Technologies Across the
Line
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.
After dehydration, the next step is ProLogium's groundbreaking
and exclusive technology, "Electrode Assembly to Form an Inlay."
This process precisely aligns and attaches 12 pieces of cathode and
anode electrodes simultaneously through a single hot pressing. By
applying high temperature and pressure, this technique reduces
interface resistance and enhances 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
Yield is the last hurdle to overcome for mass-producing
next-generation batteries. Achieving high yield rates from
single-layer to multilayer production is not as simple as stacking
electrodes together; it typically takes many years to accomplish.
Among ProLogium's more than 800 patents, hundreds are related to
yield enhancement, covering areas from cell structure to process
design. The most critical of these is the Logithium™ printer,
exclusively at ProLogium. This patented printer ensures precise
alignment and attachment during manufacturing, while also acting as
a moisture barrier and preventing short circuits. This technology
has enabled 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.
The laminator process presses and attaches a special heat-resistant
carrier film to the substrate, making it thinner, stiffer, and more
thermally resistant, thereby increasing the cell's energy density.
This carrier film can be recycled in back-end processes to be
reused, further reducing costs. Regarding the flexo-printing
process, it prints alignment marks on the substrates to achieve the
precise alignment and attachment required for lithium ceramic
battery production, enhancing yield. Later in the calendering
process, it involves hot pressing with high temperature and
pressure, making the electrodes more compact and improving ion and
electron conductivity and energy density.
Pioneering the Use of 100% Silicon Anode: ProLogium's "P-C-R
Next-Generation Battery Solution" with Lithium Ceramic
Batteries
ProLogium's revolutionary battery architecture not only creates
a safer next-generation battery but also enables the use of
advanced cathode and anode materials to enhance driving range.
ProLogium leads the industry by using a 100% silicon anode with its
patented silicon composite material (SCM), offering high
utilization and low cost. Combined with the ceramic separator's
high safety, preventing short circuits, the volumetric energy
density can reach 700-900 Wh/L. If ultra-thin lithium metal or an
anode-free design is used, the density can reach 900-1,100 Wh/L.
This approach maximizes resource efficiency and reduces costs,
resulting in a solution that perfectly balances Performance, Cost,
and Resource Circulation (P-C-R). ProLogium's P-C-R solution
addresses current industry pain points and can be applied across a
variety of industries and products.
"A new era has begun," remarked Vincent
Yang, founder and chairman of ProLogium. "ProLogium's
lithium ceramic batteries and next-generation battery technology
are leading the battery industry into a new chapter, setting the
stage for the next 30 years. Our revolutionary battery architecture
is entirely different from traditional lithium-ion batteries. It
increases energy density while maintaining fast-charging
capability, achieving a 5-minute fast charge. Remarkably, after 800
deep cycles under fast-charge conditions, the battery retains 80%
of its capacity, delivering greater value to consumers. Our Taoke
demonstration factory is proof that we are the first to make mass
production possible, serving as a prototype for our ongoing
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!"
