AI Customer ServiceIf one therefore allows 400 g of Lithium (2.1 kg LCE) per battery kWh with a 70% processing yield to produce that, an initial 3 kg of raw technical grade Lithium Carbonate will be required per kWh of final usable battery capacity.
Therefore from a purely theoretical perspective, 1000 Watt Hours or 1 kWh of energy, the basic unit of energy we consider for EV battery storage, would require 1000 divided by 13.68 = 73 grams of Lithium metal. This equates to 385 grams of Lithium Carbonate.
This equates to 385 grams of Lithium Carbonate. The theoretical figure of 385 grams of Lithium Carbonate per kWh battery capacity is substantially less than our guideline real-world figure of 1.4 kg of Li2CO3 per kWh.
In a more detailed report3 from ANL, estimates are presented varying between 113 g and 246 g of Lithium (600 g and 1.3 kg LCE) per kWh for various cathode types of batteries all with a graphite anode, with a Lithium titanate spinel anode battery having a high requirement of 423 g Li (2.2 kg LCE) per kWh.
So, it takes 136 cells with a 2 Ah capacity to form a 1 kWh battery from 18650 batteries. Do Better Cells Require Fewer to Form a 1 kWh Battery? A better 18650 will be 3000 mA or more, so let's use 3.2 Ah as an example. If you multiply 3.2 Ah by 3.7 volts, you will see that a 3.2 Ah 18650 contains 11.84 Wh of energy.
This translates into a Lithium requirement of at least 320 g of Lithium (1.7 kg LCE) per kWh of available capacity. In addition, Lithium has to be added to this for the electrolyte, irreversible capacity loss and capacity fade. EV batteries will be 25% oversized to account for capacity fade.
