LG Chem used about the identical quantity of cobalt as Panasonic, however delivered much less GWh
Cobalt is a vital component for lithium-ion batteries utilized in electrical vehicles. Producers are creating new cells with much less cobalt content material (beneath 10% of cathode weight) to lower prices and reliance on cobalt sources.
In keeping with Adamas Intelligence, three prime cell suppliers by complete capability in 2018 – Panasonic, LG Chem, CATL – deployed extra cobalt than all of the others mixed.

The fascinating teaser of the report reveals the High 5 suppliers:
There isn't any BYD, as we imagine it makes use of principally LiFePO4 cathode materials batteries.
We don’t have information but for EV battery gross sales in 2018, however taking into account that Panasonic is means above the opponents (see leads to 2017), we will draw some assumptions.
For instance, LG Chem, which but wants to change to NCM 811 batteries (nickel:cobalt:manganese at a ratio of eight:1:1 zero 10% of cobalt) might be nonetheless utilizing – on common – a comparatively excessive portion of cobalt. Alternatively, evidently Panasonic is utilizing the bottom quantity of cobalt per kWh of capability. Low utilization of cobalt in Tesla/Panasonic cells was hinted at by Elon Musk by the way in which of Q1 2018 report, which in fact catched our consideration.
The decrease the quantity of cobalt per kWh of cell, the decrease – at the very least in idea – needs to be the fabric value of the lithium-ion cell. Nonetheless, particular properties of cobalt make it tough to exchange with different chemistry, so there may very well be a downside in efficiency. Ongoing developments are on a brand new idea that might allow eliminating cobalt, with out sacrificing performances of the cells.
Listed below are battery manufacturing leads to 2017 – as all suppliers are increasing, the proportion between Panasonic and LG chem in all probability is not going to change considerably (Panasonic remains to be anticipated #1):
