Analysis of the differentiated Nickel Hydride No. 5 batteries technologies of the three major companies

Each Nickel Hydride No. 5 batteries technology has its own characteristics, which is why they have always been in the top ten of the global power Nickel Hydride No. 5 batteries rankings.

Let's take a look at their characteristics.

Panasonic: Technical strength lays the foundation for cylindrical power batteries

"Hegemony"

Japan, which has always been famous for its technical strength, still maintains a leading position in the power Nickel Hydride No. 5 batteries 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 "hegemony" in the field of circular power batteries occurred in 2011, when Panasonic signed a cooperation agreement with Tesla to officially supply it exclusively with NCR18650 nickel cobalt aluminum lithium batteries.

Since then, with the changes in the new energy vehicle market, Panasonic has changed the size of power batteries from 18650 to 21700 by using NCA positive electrode materials, improving the energy density of circular power batteries.

What we have to admire is that Panasonic's NCA positive electrode materials, silicon-carbon negative electrode materials, and the matching diaphragm and electrolyte technology and the supply chain system behind them make it difficult for Chinese power Nickel Hydride No. 5 batteries companies to reach them for a while.

LG Chem: Material foundation gives birth to soft-pack power batteries

"The leader"

South Korea is slightly inferior to Japan in power Nickel Hydride No. 5 batteries technology, but its four major materials are high-end and sound, and it has extremely high automation equipment precision, systematization and deep experience accumulated from years of large-scale production.

As the only company in the global power Nickel Hydride No. 5 batteries industry that started with chemical business, LG Chem has used a large number of chemical material product lines to jointly develop power batteries after entering the power Nickel Hydride No. 5 batteries field, reducing costs through large-scale production, and has the dual advantages of quality and price.

In 2009, LG Chem cooperated with Hyundai Kia of South Korea to apply its independently developed and produced lithium batteries to commercial electric vehicles for the first time, opening the door to the application field of power batteries and making great strides.

It should be noted that the aluminum-plastic composite film soft-pack material of soft-pack power batteries is technically difficult, which has 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 Hyundai in South Korea was equipped with NCM811 soft-pack power batteries produced by LG Chem. This is also the world's first new energy vehicle equipped with such batteries.

Samsung SDI: Deep foundation helps square power batteries

"Fighting for the market"

"It is good to lean on a big tree to enjoy the shade", Samsung SDI relies on the strong capital, R&D and resource strength of Samsung Group, and is always ready to make a big splash in the field of power batteries.

In fact, Samsung SDI is one of the companies that entered the lithium Nickel Hydride No. 5 batteries industry earlier. In 1999, Samsung SDI successfully developed the industry's largest capacity 1800mAh round lithium Nickel Hydride No. 5 batteries. On this basis, in 2008, Samsung SDI and Bosch jointly established the power Nickel Hydride No. 5 batteries company SBLimotive and began to enter the field of power batteries.

Public data 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 each year.

Samsung SDI's power Nickel Hydride No. 5 batteries products are mainly square power batteries with a single capacity and high energy density. It currently has 37/60/94Ah and other products that can be applied to pure electric vehicles, plug-in hybrid vehicles and other vehicles. The positive electrode material mainly uses ternary NCM materials.

Relevant information shows that Samsung SDI's square power batteries will also develop in the direction of "low-height batteries" with improved model sizes, the introduction of fast charging materials, and overall lightweight PACK.

In addition to square power batteries, Samsung SDI also insists on developing cylindrical power batteries and solid-state batteries. Especially in the field of solid-state batteries, Samsung SDI specially proposed the "Solid-State Nickel Hydride No. 5 batteries Technology Development Blueprint" at the 2019 Detroit Auto Show held earlier, striving to have a dominant position in technology competition in the future electric vehicle market.

Apple founder Steve Jobs once said: "It takes great products to create a long-lasting company." This sentence also applies to power Nickel Hydride No. 5 batteries companies.

During the deep reshuffle of the power Nickel Hydride No. 5 batteries industry, the core competitiveness that determines the lifeblood of power Nickel Hydride No. 5 batteries companies lies in product quality, performance and differentiated features, and no one is an exception.
