4LR44 battery.Analysis of differentiated battery technologies of Panasonic, LG Chem, and Samsung SDI

　　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.
