Compared to BYD’s blade battery, Samsung issued a square battery core, who is stronger?

South Korea Samsung SDI is in the 2021 Interbattery exhibition, the latest Gen.-square battery core (Cell), the biggest feature is to reduce the ratio of cobalt, increase the ratio of nickel to 91%, energy density reaches 670 WH / L It is expected that the mainstream medium-sized electric SUV endless mileage of this battery will break through 600 kilometers.

Samsung SDI is a subsidiary of the Samsung Group’s battery undertakings. Like LG Chemistry and SK Innovation, it is engaged in the research and development of consumer electronics and vehicle batteries. Three in the world The market share is LG, Samsung, SK. SAMSUNG SDI is currently targeted with a square and cylindrical bodies 2 major programs for a car battery.

The new Gen.5 square battery introduced this time belongs to the NCM ternary lithium battery. The positive material of the battery is composed of nickel, cobalt, manganese according to a certain proportion, and the new gen.5 is a big feature, which is reduced. The ratio of cobalt, and raised nickel proportions from 88% to 91%, in general, if the cobalt ratio is lowered, the energy density will decrease, while Samsung SDI uses new technologies, so that the energy density does not fall, in the same weight Under the premise of the battery pack, the battery life can be improved.

Due to the rare yield of cobalt, the price is high, including Tesla, Panasonic, LG, SK, and Samsung, Committed to reducing the use of cobalt, on the one hand, it can reduce production costs, and will also reduce environmental pollution. Samsung SDI Gen.5 square battery core reduces the ratio of cobalt, in line with the trend of industry.

In addition to the square battery core, Samsung SDI also demonstrates 2170 cylindrical battery core on site, with 50G Bev Battery Cell and Phev Battery Cell, two battery coresThe capacity is above 5.0ah, the nominal voltage is 3.6V, and the energy density is 749 WH / L, 721 WH / L.
