Each battery technology has its own characteristics and characteristics.
Because of this, they have always been in the top ten of the global power
battery rankings.
Let’s take a look at what their characteristics are.
Panasonic: Technical strength lays the foundation for cylindrical power
batteries
"overlord"
Japan, which has always been famous for its technological strength, still
maintains its leading position in the power battery industry. The Japanese have
mastered the core technology and patents of lithium batteries. Panasonic has
been working hard in the field of cylindrical power batteries for more than 20
years and has formed a unique technical advantage.
The historical moment that established Panasonic's "dominance" in the field
of circular power batteries occurred in 2011, when Panasonic signed a
cooperation agreement with Tesla to officially supply it with NCR18650 lithium
nickel cobalt aluminate batteries exclusively.
Since then, with the changes in the new energy vehicle market, Panasonic
has increased the energy density of circular power batteries by using NCA
cathode materials to change the size of power batteries from 18650 to 21700.
What has to be admired is that Panasonic’s NCA cathode materials, silicon
carbon anode materials, matching separator and electrolyte technologies and the
supply chain system behind them have made it difficult for Chinese power battery
companies to match them.
LG Chem: Material foundation gives rise to soft-pack power batteries
"Carry the handle"
South Korea is slightly behind Japan in terms of power battery technology,
but its four major materials are high-end and sound, and it has extremely high
automation equipment precision, systematization, and deep experience accumulated
in many years of large-scale production.
As the only company in the global power battery industry that started out
based on the chemical business, LG Chem has used a large number of chemical
material product lines to collaboratively develop power batteries after entering
the power battery field. It has reduced costs through large-scale production and
has dual advantages in quality and price. .
LG Chem cooperated with South Korea's Hyundai Kia in 2009 and applied its
independently developed lithium batteries to commercial electric vehicles for
the first time. Since then, it has opened the door to the field of power battery
applications and has been making rapid progress.
You should know that the aluminum-plastic composite film soft packaging
material for soft-pack power batteries is technically difficult, which has also
become a difficult threshold for some companies to enter the field of soft-pack
power batteries. Based on its own advantages, LG Chem has always occupied the C
position in the field of soft-pack power batteries.
At the beginning of 2018, the Kona pure electric SUV released by South
Korea's Hyundai was equipped with NCM811 soft-pack power batteries produced by
LG Chem. This is also the world's first new energy vehicle equipped with this
type of battery.
Samsung SDI: Deep foundation helps square power batteries
"Competing for the market"
"It's easy to enjoy the shade with a big tree at your back." Samsung SDI
relies on Samsung Group's strong capital, R&D and resource strength to
always be ready to flex its muscles in the field of power batteries.
In fact, Samsung SDI is one of the earliest companies to enter the lithium
battery industry. In 1999, Samsung SDI successfully developed the industry's
largest capacity 1800mAh circular lithium battery. On this basis, in 2008,
Samsung SDI and Bosch jointly established the power battery company SB Limotive
and began to enter the power battery field.
Public information shows that Samsung SDI has more than ten years of
large-scale production experience in the field of lithium batteries and sells
more than 1 billion batteries every year.
Samsung SDI's power battery products are mainly prismatic power batteries
with a single capacity and high energy density. Currently, it has 37/60/94Ah
products that can be used in pure electric vehicles, plug-in hybrid vehicles and
other vehicles. The cathode material is mainly used Ternary NCM material.
Relevant information shows that Samsung SDI’s prismatic power batteries
will also develop in the direction of “low-height cells” with improved model
sizes, introduction of fast charging materials, and overall lightweight
PACK.
In addition to prismatic power batteries, Samsung SDI also insists on
developing cylindrical power batteries and solid-state batteries. Especially in
terms of solid-state batteries, Samsung SDI specifically proposed a "Solid-state
Battery Technology Development Blueprint" at the previously held 2019 Detroit
Auto Show, striving to dominate technological competition in the future electric
vehicle market.
Apple founder Steve Jobs once said: “To create an enduring company requires
great products.” This sentence also applies to power battery companies.
In the deep reshuffle of the power battery industry, the core
competitiveness that determines the lifeblood of power battery companies lies in
product quality, performance and differentiated features, and no one is
exception.
