Recently, South Korea "TheEguctronictimes" held "2021 Battery Day". LG Energy Solution (LGENERGYSOLUTION) The person in charge of the electric vehicle development center Cuiseung-Don attended the event and delivered a speech, indicating that the company plans to realize the commercialization of lithium sulfur batteries at the end of 2025, and achieve full solid state between 2025 and 2027 Battery commercialization. Among them, "lithium sulfur batteries may be commercialized earlier than full solid state".

This is the first-generation battery development progress and commercial plan for the first generation of battery development. LG Energy 2024 Sword refers to the world's first launch of solid state battery transition methods In addition, the LG Energy Solution Program has reached 260GWH production by 2023, "this will be the highest production in the world". It is worth mentioning that Cui Sheng East detailed the company's development strategy for electric vehicle battery: • The goal of LG energy solution is to achieve $ 270 billion sales in 2024, and become the first company in electric vehicle battery; • The company is currently considering carrying lithium sulfur batteries on electric vehicles; • For large and full-size luxury electric vehicles, companies will introduce high-nickel NCMA batteries (including 80% of nickel, and an anode material are silicon groups); Electric cars, the company plans to develop battery packs containing approximately 65% ​​of nickel;.

Lithium sulfur battery: new battery new choice? The LG energy solution was established in December last year, from LG chemical split. At the beginning of the founding, the company will use a new generation of battery technology such as full solid state batteries and lithium sulfur as an important development direction and an increase engine. The lithium sulfur battery is still a more unfamiliar concept compared to the full solid state of the recent boiling.

According to the data, the lithium sulfur battery is a lithium ion battery in a positive electrode, lithium as a negative electrode. Under normal circumstances, the positive electrode material is the key to the performance, cost, battery capacity of lithium ion batteries. The lithium sulfur battery of the sulfur is used as the positive material, theoretically energy density is 1.

5 times the lithium ion battery. From an economic point of view, the sulfur reiciency is rich, the price is low; it is also more convenient than metal during recycling. In addition, the greatest advantage of lithium sulfur batteries is light, so it is also suitable for aircraft, also a choice of urban air traffic (UAM).

Light weight and price is low, LG energy considers important causes for lithium sulfur batteries for electric vehicles - reducing the production cost of electric vehicles, and improves battery performance. In September last year, LG chemistry announced that the solar drone high-altitude test flight with lithium sulfur cells was successfully tried, and the highest record in the development of the Korean domestic drone in Korea. In December of the same year, LG chemistry verified the long-term performance of lithium sulfur batteries.

The drone of the battery was taken for 13 hours, of which 7 hours in 12-22 km high. However, Ningde Times has different opinions. Previously, LG R <000000> D cells were developed.

Ningde Times said in the interactive platform: there are some technical disadvantages of lithium sulfur cells, such as poor cycle life, low volume energy density, less suitable for current technical states for volume energy density requirements High application scenario. .
