Samsung Sdi Battery (South Korea)top 5 lithium battery factory

Market share reference value: 3.6%; installed capacity: 8GWH.

Global position: Samsung SDI dominates the global small consumer lithium battery market. BMW has launched a pure electric vehicle, the Megacity power battery supplier.

Overview and technical features: Samsung Group is the largest multinational conglomerate in South Korea, and its business involves electronics, finance, machinery, chemistry and many other fields. Samsung Group was established in 1938 by Lee Byung-cheol. The Samsung Group is a family business, and the Lee family is hereditary. Each of its Samsung businesses is a family business and is managed by other members of the family.

Its subsidiaries include: Samsung Electronics, Samsung SDI, Samsung SDS, Samsung Electro-Mechanics, Samsung Corning, Samsung Networks, Samsung Fire, Samsung Securities, Samsung C&T, Samsung Heavy Industries, Samsung Engineering, Samsung Aviation and Samsung Life, among which three subsidiaries are Selected as one of the world's top 500 companies by Fortune magazine. Samsung Electronics is its largest subsidiary. Among the top 500 companies in the world in 2009, Samsung Electronics occupied the 40th place. The world's most respected companies ranked 50th, and Samsung's brand value ranked 19th.

According to the research report previously released by GF Securities: Among the top ten lithium battery companies in the world, there are two in Japan and two in South Korea, and the rest are all Chinese companies, of which CATL and BYD are the leaders in China. According to the starting point research statistics, Japan's Panasonic and Sony once accounted for 16.7% of global sales, South Korea's LG Chem and Samsung SDI accounted for 22.5%, and most of the rest were produced in China. As early as 2000, Samsung SDI began to enter the field of power batteries. In 2015, Samsung SDI 100% acquired MSBS, a subsidiary of MagnaSteyr engaged in the battery business. Since then, Samsung SDI has built a complete electric vehicle battery business system from battery cells, modules to battery packs. In the global small consumer lithium battery market, it can be said that Samsung SDI comes out on top. However, in the field of power batteries, compared with the global giants Panasonic and LG Chem at that time, Samsung SDI was slightly inferior in terms of operating income and power battery shipments.

In 2009, BMW launched the pure electric car Megacity, and SBLimotive became the Megacity power battery supplier, opening the power battery market for Samsung SDI. In July 2014, Samsung SDI and BMW signed a memorandum of understanding to expand the supply of electric vehicle batteries and jointly develop a new generation of battery materials, further consolidating the partnership between Samsung SDI and BMW in power batteries. It is worth mentioning that Samsung SDI has been selected as the core battery supplier for more than 30 vehicle electrification projects, and the number of projects is increasing. For example, the first vehicles to install Samsung SDI batteries are the Fiat500e (pure electric car), BMW i3 (pure electric car), BMW i8 (plug-in hybrid) and many other models from OEMs.

samsung 21700 battery

Samsung SDI is different from Panasonic and LG Chem. The packaging form of Samsung SDI power battery is mainly square. At the same time, it actively follows up the production of 21700 battery. The positive electrode material mainly uses ternary NCM and NCA materials. Prismatic hard case batteries are capable of producing high-capacity single cells. In addition, the rectangular battery shells are mostly made of aluminum alloy, stainless steel and other materials, and the internal use of winding or lamination process, the protection of the battery is better than that of aluminum-plastic film batteries (ie soft-pack batteries), and the safety of the battery Relatively cylindrical batteries have also been greatly improved. The disadvantage of square batteries is that there are too many models, and the process is difficult to unify.

Samsung SDI relies on the strong capital, R&D and resource strength of Samsung Group to show its talents in the field of power batteries. In addition to square power batteries, Samsung SDI also insists on developing cylindrical power batteries and solid-state batteries. Especially in terms of solid-state batteries, for example, Samsung SDI put forward a "blueprint for the development of solid-state battery technology" at the 2019 Detroit Auto Show, striving to dominate the technology competition in the future electric vehicle market. Apple founder Steve Jobs once said: "Creating a long-lasting company requires great products." This sentence also applies to power battery companies. In fact, in the process of deep reshuffle in the power battery industry, the core competitiveness that determines the lifeblood of power battery companies lies in product quality, performance and differentiated characteristics, and no one will be an exception.
