To discuss the development of LG Chemistry, SK Innovation and Tesla Panasonic Battery

According to foreign media reports, in recent years, the development of electric vehicles has been in full swing, and electric technology has changed rapidly. To this end, the small compilation of LG Chemistry, SK Innovation and Tesla Panasonic battery research and development information for readers to taste.

LG Chemistry

According to PushEVs, LG Chemical's battery roadmap is very clear. The company focuses on the cathode materials of the NMC 811, thereby consolidating its leading position in the battery market. In addition, the company's battery energy density is higher and the cost is lower. Now that third-generation mass-produced batteries have been used in electric passenger cars, they have taken another big step in terms of energy density and reducing costs to improve charging performance.

The company has increased the amount of alumina in NCMA batteries and less than 10 per cent in cobalt, which will be mass-produced by 2020. The contents of nickel, cobalt and manganese in the 622 ternary battery were 70 %, 10 % and 20 %, respectively. However, the company has now increased the nickel content of NCMA batteries to 90 %, and the battery is under development. The 712 battery is also in the development stage and will be mass-produced within the next 2-3 years.

So far, LG Chemicals has produced NCM811 batteries only for electric buses, but NCM622 bags for electric vehicles have a higher energy density. It is worth mentioning that modern Kona Electric will use LG Chemical's NCM622 battery.

SK Innovation

The company plans to mass-produce the NCM811 battery core in August 2018. The product can be used by electric vehicles. Kia NiroEV will be the first model to use the battery.

Tesla-Matsushita

Tesla claims that the model3's car battery has the highest energy density in the industry, cutting cobalt content and increasing nickel content, calling it a new generation of NCA battery chemical ratios, but its battery cathode is produced by other manufacturers.

brief summary

LG Chemical is expected to produce 712 batteries from 2020, SK Innovation will start production of 811 cores this year, and Tesla's production schedule is not yet clear. With Tesla Panasonic, the battery's energy density is ahead of the industry, reducing costs by increasing the nickel content of the cathode and reducing its cobalt content.

All in all, with the continuous development of electric vehicle technology, the competitiveness of electric vehicles is getting bigger and bigger.
