3.7 volt battery 18650

release time:2024-04-01 Hits:     Popular:AG11 battery

  Is the energy density of ternary 3.7 volt battery 18650 high? What are the technical ways to improve the specific energy of power ternary lithium batteries?

  Is the energy density of ternary 3.7 volt battery 18650 high?

  Ternary lithium-ion power batteries have now seen the ceiling of energy density. The maximum energy density of a 3.7 volt battery 18650 with high nickel materials and carbon-silicon anode should be around 300Wh/kg, plus or minus no more than 20Wh/kg. At present, most of the power batteries used in pure electric vehicles in my country's new energy vehicle market are ternary 3.7 volt battery 18650 materials and lithium iron phosphate battery materials. Although the energy density has been greatly improved compared to lead-acid and nickel-metal hydride batteries, it is still difficult to dispel consumers' range anxiety.

  The single energy density of BYD's lithium iron phosphate battery is 150Wh/kg, and the energy density of BYD's ternary 3.7 volt battery 18650 reaches 200Wh/kg. It can be seen that the advantages of ternary lithium materials over lithium iron phosphate are still very obvious. BAK Battery, another battery company in Shenzhen, has a ternary material power battery with a single cell energy density of nearly 220Wh/kg, which is relatively high in the industry. From the perspective of adaptation policies, future energy density requirements will be higher, and the potential of ternary lithium batteries will be further unleashed.

  The biggest advantage of ternary lithium batteries is the high energy density of the battery. Its energy storage density is usually above 200Wh/kg. Compared with 90-120Wh/kg of lithium iron phosphate, this performance is more friendly to lightweight design and more convenient. It is suitable for the current demand for cruising range in the new energy passenger vehicle market.

  Technical ways to improve the specific energy of power ternary lithium batteries

  1. Process progress has been made, but now the battery process design is relatively mature, and there is not much room to improve the specific energy of the battery;

  2. The improvement of material performance is limited by its own physical and chemical properties. Lithium-ion power batteries using lithium iron phosphate and ternary lithium as the positive electrode and carbon materials as the negative electrode are difficult to make major breakthroughs in energy density;

  3. New materials and new systems, that is, the development of new materials with high specific energy and the development of new systems for power ternary lithium batteries are the main ways to significantly increase the specific energy of power batteries in the future.

  4. The energy density of 3.7 volt battery 18650 packs is a systemic issue. Improving the energy density of the cells is a direct method. However, if the cell layout and circuit planning are done well, the weight of the casing can be reduced, and the burden on the battery can be reduced, it will also improve the battery energy density. an effective means.
