The Second Revolution of Automobile Industry, the Core of Realizing "The Electricalization of Automobile!" Batteries for xEV

The Paradigm of Automobile Industry is changing

Internal combustion engines, especially batteries, that grew up with 100-year-old automobile history starts to earnestly become electricalized. The electricalization that is called the second revolution of automobile has become essential for automobile companies to keep up with the new trend that pursues "pro-environment" and "high fuel efficiency".

The electricalization of automobile begins with hybrid cars that are combined with internal combustion engines. These cars are then developed into plug-in hybrid, electric automobiles. As the electricalization accelerates, the power-transmitting role of internal combustion that the engine reduces, the electric motor and batteries expand. Ultimately, the result is an automobile driven fully by 100% electricity without utilization of any oil. For developing xEV that includes hybrid, plug-in and electric automobile, battery technology development is necessary.

Lithium batteries are expected to be mainly used for xEV
Compared to the nickel-hydrogen type batteries which are used in hEV cars like the Toyota Prius, Lithium ion batteries have twice the amount of energy given the same weight which enables xEV to guarantee longer mileage and have double the output for the same volume. Long life is also a big merit of lithium ions. xEV automobile guarantees more than twice the life span since lithium ion batteries have no memory effect when repeating charge and discharge. Due to this merit, lithium ion batteries are mainly used as the batteries for xEV automobile.

Facing the new paradigm of automobile industry, Samsung SDI promises to lead the xEV battery market by our world-best lithium ion cell technology.

The Characteristic of XEV Batteries

must have a large output

The motor of xEV automobile runs in start, hill driving and high-speed driving. At this moment lithium batteries should be able to supply energy instantly to the motor, which means the battery must output 50 times as much energy than a laptop computer.

must have a long life span

For battery use without change while using xEV automobile, a long life span(15 years of use period, 25000km of mileage and 5000 times of cycle life) is necessary.

must have great safety

Since batteries that with enough of a large output to drive a car is necessary, much electric current is added during the charge. As a result, great safety is necessary. In addition, fire by the impacts of car accidents must be prevented.
