How much lithium does a ternary lithium car need?

60 kWh lithium iron phosphate battery, a car requires 30 kgof lithium carbonate.

If we calculate based on 60 kWh per vehicle, 100,000 vehicles equal 6 GWh and 1 million vehicles equal 60 GWh. The corresponding demand for lithium carbonate is 30,000 tonnes respectively. According to China's lithium carbonate production in 2020, it will be 166,000 tons, an increase of 4.4% year-on-year, including 106,000 tons of battery-grade lithium carbonate and 60,000 tons of lithium carbonate. industrial grade lithium. . In other words, 100,000 tonnes of battery-grade lithium carbonate, all used to make lithium iron phosphate batteries, is 200 GWh.

If we use three yuan, taking LG products used by Tesla as an example, the material can be roughly broken down into 51.75 kWh. According to the demontage, the weight of the battery core is 201.68 kg, and. the corresponding cathode material weight is 80 kg, the corresponding weight of nickel is 65.57 kg, and the weight of cobalt is 4.8 kg. If the price is 100,000 yuan per ton (100 yuan/kg), the price of nickel is 655 yuan, and the price of cobalt is 350,000 yuan per ton (350 yuan/kg), the corresponding price is 1 679 yuan, which totals to approximately 2,334 yuan.

As shown below, the 60V12AH lithium battery and 60V1000W motor can run approximately as many miles as they can travel. How many years can this lithium battery be used?

Let's talk about Wh (. Watt hours) first. Do you know the battery at home? An electricity meter is measured in KWh (kilowatt hour), which represents the amount of electricity needed to run a 1000W electrical appliance for one hour. It's the same for batteries,1KWh = 1000Wh, but the battery capacity is smaller and expressed in Wh, so 100-115Wh is the power consumed by an electrical appliance of 100-115W for 1 hour of work, you understand?

Let’s talk about Wh/Kg. If an electrical appliance of 100-115 W works for an hour, then the mass of the lithium battery will reach 1 kg, so Wh/kg is the unit of energy density. The energy density of nickel-metal hydride batteries is lower than that of lithium batteries, which is around 80 Wh/kg. Nickel-cadmium batteries are smaller, around 50 Wh/kg.

ps: This answer is absolutely original to me.

Approximately 3 to 5 years.

The capacity of this lithium battery is 60*12=720WH=0.72KWH. Electric vehicles have a power consumption per 100 kilometers, basically 1.3~1.5KWH/100KM, so the theoretical driving distance is =0.72. KWH/1.3~1.5KWHX100KM=48~55KM.

However, the useActual is affected by other factors such as human weight, road conditions and wind, power conversion efficiency, etc. The actual distance is about 70% of the theoretical distance, or 33.6 ~ 38.5. K.M.

Lithium battery life cycle: The normal life of a lithium battery is 300 cycles with a capacity retention rate of 80%, a good battery can reach 500 cycles . After charging once a day, it can travel 25.5-30.8 km after one year of use. Normally it can be used for 3-5 years.

Detailed information:

Precautions for using lithium batteries:

1 It is recommended that the battery temperature or +5 ℃. ~+30℃ (It is best to use it under temperature conditions of 25℃). High temperature will shorten the lifespan and reduce the low temperature capacity

2. brands, different capacitiesés, old and new batteries;

3, the battery will produce hydrogen during use, so stay away from fire sources, maintain ventilation and avoid explosion

4; . Please keep the environment clean, too much dust may cause the battery to short circuit;

5. The battery should be recharged in time after being discharged, which will cause the battery capacity to be reduced. or even damaged, so a suitable charger must be configured;

6. The inverter load is too light (such as 1KVAUPS with 150VA load) may cause deep battery discharge, which should be avoided as much as possible; possible ;

7. Proper discharge will help activate the battery. If the mains power is not turned off for a long time, the battery should be discharged manually 2-4 times per year. be used to discharge, and the time is 1/4 to 1/3 of the timebackup;

8. Batteries (UPS) that have been out of service for a long time should be charged and stored, and every six months the battery should be charged and discharged once. Generally, the battery is charged for about 4-10 hours and the battery works in inverter state for 2-3 minutes.
