Samsung is more and more frustrated: Cheng also battery, defeated battery

Since the Samsung Note 7 battery explosion, the "Boom" label has followed. In this incident, first of all, we must admit that Samsung’s efforts to issue a recall order have preserved the last glimmer of hope of Samsung in the minds of consumers, but it is deeply worrying because it is not only Samsung’s exclusive possession of this “Boom” in everyday examples. It can be said that any mobile phone on the market may have such a situation, but the probability is small. Samsung has a wide impact area and a bad accident, and it is naturally crushed by public opinion.

The main reason is the battery. Samsung and battery suppliers have adopted new technologies on Note7 batteries to improve performance. The risky approach is most likely to bring unpredictable consequences. This incident obviously directly affects this diversified company, especially in Battery side. After this battle, not only the sales trend of mobile phones is going to be big, but the revenue of Samsung will be reduced by 5 billion US dollars, and the annual profit rate will be reduced by 5%. This is only a loss on the surface. The most difficult thing is that consumers hold Samsung products. The sense of distrust.

In September 2016, the Korean media quoted Samsung Electronics as saying that “for reasons that are well known, Samsung decided to suspend the use of battery products supplied by SDI”. SDI is said to provide about 70% of Samsung Note7 batteries, and the remaining 30% of the batteries are provided by Hong Kong manufacturer New Energy Technology. Since 30% of Samsung Note7, which is supplied by New Energy Technology, is sold in mainland China, it is not on the global recall list. Inside.

Originally thought that Samsung and SDI have been doing their own thing, but I can't think of a situation in which the lips are cold. At present, Samsung SDI, which produces related batteries, continues to intensify new product development. It is reported that Galaxy S8 will continue to use Samsung SDI battery products in the future, and at the same time, in order to show the attitude of Samsung reactor battery, at this year's Detroit North American International Auto Show, Samsung SDI A prototype of a battery for an electric car is publicly displayed.

This is a high-energy-density battery designed to provide a roadside charging station. When the owner is able to enjoy a cup of coffee (20 minutes), the car can charge at least 80% of the electricity, which can provide about 500 kilometers. The cruising range is longer than the current mainstream Tesla's full-power range. Samsung's solution is not to increase the number of batteries purely, because it will lead to an increase in the weight of the car, but hope to improve the charging technology, can provide fast charging technology similar to the current mobile phone to shorten the charging time, so that users do not Need to worry about charging time. Obviously, such batteries are not yet ready for commercial use in the short term. Samsung said that the large-scale commercial production of the battery is expected to wait until 2021.

In addition to charging technology, it is confirmed that Samsung is improving a "21700" cylindrical battery. Compared with the current 18650 battery (the bottom diameter of the battery is 18 mm and the length is 65 mm), it has a large range of energy density, output power and performance. Improvement. At present, mainstream car manufacturers are vigorously developing new 21700 batteries, including Tesla has also confirmed that its super factory has begun trial production and a new Lithium Battery jointly developed by Panasonic.

Even if the mobile phone battery fell out of a big hole, Samsung couldn’t stop his ambition. According to the current plans of major manufacturers, by 2021, the mainstream manufacturers’ electric vehicle product line will gradually improve, meaning The advancement of Electric Vehicle Battery technology is imminent, and this is also an important measure for Samsung to reverse consumers' perceptions of their batteries. It can be said that Samsung is brave, and it has contributed to the situation of Cheng also battery, and the battery is also defeated. If it is successful, it will save many consumers.
