Our innovations make your driving experience more electrified

Imagine pure electric cars with a driving range of over 300km on a single charge, or super performance cars that are not only perfect for highly competitive races, but also consuming less fuel, reducing carbon footprints.
Whatever you imagine, new innovations in Samsung SDI battery are making those dreams a reality for automakers as well as tomorrow’s drivers.
The ideal battery would be safe, small, and light while still being capable of delivering large amounts of energy. The lithium is the third lightest element (the lightest being hydrogen) and is the lightest metal, allowing lithium-ion batteries higher energy density per unit mass than other chemistries based on nickel or lead. So among lithium-ion battery manufacturers, the winner would be the one who can produce the lithium-ion battery with higher energy density within given space.
Our success in consumer IT battery applications has made us realize that we can assist the automotive industry in addressing a number of challenges such as powertrain performance, fuel economy and CO2 reductions by applying our latest battery technologies.

    Built-in safety devices tailored for automotive grade

    Thanks to its focus on safety, Samsung SDI was able to set a 15-year zero-defect track record and produce the industry’s most advanced built-in safety devices in its prismatic lithium-ion battery. Safety is the single most important factor in battery production as batteries rely on the reaction of several volatile chemicals in order to discharge electricity, and some batteries have high energy density. Samsung SDI has developed and applied its own unique safety devices such as Safety Fuse, Nail Safety Device (NDS), Overcharge Safety Device (OSD) and Safety Functional Layer (SFL) to ensure drivers’ safety even under the toughest conditions.

    Lifetime durability for better driving experience in the long-term

    The market and the public alike have been concerned as the electric vehicle’s driving distance gets shorter rapidly during the use of the vehicle. Though the capacity reduction of any battery is normal, the question is how to maintain high performance throughout the entire battery life. Samsung SDI’s prismatic battery is hermetically sealed by the laser welding assembly process, thus impervious to outside humidity, while keeping sufficient quantity of electrolyte inside to ensure long-term performance stability.

    The exterior of Samsung SDI battery cell is made of a stackable prismatic aluminum can, ideal for minimum packaging space. Also, no additional structures are required for a cooling module.

Excellence in manufacturing & greater cost reduction
Samsung SDI Automotive Battery - Excellent productivity and cost savings
Some often say that the high price is the biggest barrier in EV penetration.

By making technological changes at the manufacturing level including manufacturing automation, the overall battery cost can be brought down, increasing yields and production speed. The market order will be shaped in accordance with manufacturing yields as the EV market grows - new entrants with technological competence at smaller scales are likely to face production difficulties and higher manufacturing costs.
Samsung SDI has a 15-year experience of lithium-ion battery mass production. It sold over 7 billion cells for the past 15 years and is now selling over 1 billion cells per year. The production lines of Samsung SDI are 100% automated. Furthermore, prismatic lithium-ion battery that Samsung SDI supplies for automotive applications has a relatively short production lead time and high process stability leading to higher productivity and cost reduction compared to other types of batteries.
In addition, roughly 80% of the raw materials used in IT batteries are used in automotive batteries so we achieve better economies of scale through large-scale procurement leveraging the total value chain.

Unrivalled track record in safety through meticulous quality control
Samsung SDI Automotive Battery - Productivity

The lithium-ion battery production is a highly complex process incorporating various materials, chemistries, hardware, and software and requires a higher degree of quality control. Strict and consistent quality control is critical because defective products can be attributable to more than one factor throughout the processing chain, such as imperfect materials, defective equipment, or manufacturing errors.
Samsung SDI can say with confidence that it is the one and only company that has not had any quality-related accidents all thanks to its strict disciplines in engineering and manufacturing.
Besides standard automotive quality tools like FMEA (Failure Mode and Effects Analysis) and sub-supplier management systems, Samsung SDI has developed and installed advanced internal processes such as its Manufacturing Executing System (MES) in order to guarantee the highest quality of its products and 100% traceability. As a result, every battery cell produced by Samsung SDI is checked at hundreds of measuring points during the production process and can be individually tracked. This ensures that customers will always get battery cells with the most consistent and highest performance during the entire vehicle lifetime.
