Let's take a look at their characteristics.
Panasonic: Technological Strength Lays Foundation for Cylindrical Power Batteries
"overlord"
Japan, renowned for its technological prowess, continues to lead the power battery industry. The Japanese possess core technologies and patents for lithium batteries, and Panasonic, with over 20 years of experience in cylindrical power batteries, has developed a unique technological advantage.
The historic moment that solidified Panasonic's "dominant" position in the field of cylindrical power batteries occurred in 2011 when Panasonic signed a cooperation agreement with Tesla, officially becoming the exclusive supplier of NCR18650 nickel-cobalt-aluminum lithium batteries to Tesla.
Subsequently, with changes in the new energy vehicle market, Panasonic used NCA cathode material to change the size of power batteries from 18650 to 21700, thereby improving the energy density of cylindrical power batteries.
One has to admire Panasonic's mastery of NCA cathode materials, silicon-carbon anode materials, and the matching separator and electrolyte technologies, along with its underlying supply chain system, which is something that Chinese power battery companies can hardly match for the time being.
LG Chem: Materials-based approach drives the development of pouch cells for power batteries
"The boss"
South Korea lags slightly behind Japan in power battery technology, but its four major materials are high-end and well-developed, and it possesses highly precise and systematic automated equipment, as well as extensive experience accumulated over many years of large-scale production.
As the only company in the global power battery industry that started with a chemical business, LG Chem has leveraged its extensive chemical materials product lines to collaboratively develop power batteries after entering the field. Through large-scale production, it has reduced costs and gained advantages in both quality and price.
In 2009, LG Chem partnered with Hyundai and Kia of South Korea to apply its self-developed and manufactured lithium batteries to commercial electric vehicles for the first time, thus opening the door to the application of power batteries and making great strides ever since.
It's important to understand that the aluminum-plastic composite film material for pouch batteries is technologically challenging, posing a significant hurdle for some companies entering the pouch battery market. LG Chem, leveraging its strengths, has consistently maintained a leading position in the pouch battery sector.
In early 2018, Hyundai's Kona electric SUV was equipped with NCM811 pouch batteries produced by LG Chem, making it the world's first new energy vehicle to use this type of battery.
Samsung SDI: Deep Foundation Supports Square Power Batteries
"Competing for the market"
"It's good to have a big tree to lean on." Samsung SDI, relying on the strong capital, R&D and resources of the Samsung Group, is always ready to make great strides in the field of power batteries.
In fact, Samsung SDI was one of the earliest companies to enter the lithium battery industry. In 1999, Samsung SDI successfully developed the industry's largest capacity 1800mAh cylindrical lithium battery. Building on this, in 2008, Samsung SDI and Bosch jointly established the power battery company SBLimotive, thus entering the power battery field.
Public information shows that Samsung SDI has more than ten years of experience in large-scale production of lithium batteries, selling more than 1 billion batteries annually.
Samsung SDI's power battery products mainly consist of square power batteries with high energy density and single capacity. Currently, it has products with capacities of 37/60/94Ah that can be used in pure electric vehicles, plug-in hybrid electric vehicles, etc. The cathode material mainly uses ternary NCM material.
According to relevant information, Samsung SDI's square power batteries will also develop in the direction of "low-profile cells" with improved model size, introduction of fast charging materials, and overall lightweighting of the PACK.
In addition to prismatic batteries, Samsung SDI is also committed to developing cylindrical batteries and solid-state batteries. Particularly in the area of solid-state batteries, Samsung SDI presented its "Solid-State Battery Technology Development Roadmap" at the 2019 Detroit Auto Show, aiming to gain a leading technological advantage in the future electric vehicle market.
Apple founder Steve Jobs once said, "It takes great products to build a lasting company." This statement also applies to power battery companies.
In the process of deep reshuffling in the power battery industry, the core competitiveness that determines the lifeline of power battery companies lies in product quality, performance and differentiation features, and no one is an exception.
