Lithium-ion Full Cell Manufacturing Process Training--Design-2

1.High energy density system battery

1.1.Energy Density↗ ，Required Capacity↗， Voltage Platform↗，Weight↘，Volume↘

1.2.Set goals: (1) capacity, (2) energy density

1.3.Mass Energy Density = Capacity * Voltage Platform / Weight (Wh/kg)
Volumetric Energy Density = Capacity * Voltage Platform /Volume (Wh/L)

1.4.Material

1.4.1.Cathode Materials

1.4.1.1.In general, lithium cobalt oxide materials have high gram capacity, the highest voltage platform, the highest compaction density, and therefore the highest energy density.

1.4.1.2.At present, lithium cobalt oxide is widely used in consumer battery products, and mobile phone batteries are basically made of lithi um cobalt oxide as cathode materials.

 

Note: This table is an early reference book for lithium-ion batteries, and there have been many improvements and upgrades in recent years, such as:

 (1) At present, the maximum charging voltage of lithium cobalt oxide has been increased to 4.48~4.5V, the gram capacity has also been increased to ~185mAh/g, and the voltage platform has also been increased;

(2) In terms of price, the price of LFP has dropped to less than 100,000 yuan, and lithium manganese oxide has dropped to less than 50,000 yuan

1.4.2.Anode Materials
