Suddenly, everyone is interested in batteries.
When mobile devices took off after the launch of the iPhone, the demand for batteries with a longer life than the then existing chemistry could deliver took off as well. Panasonic held a dominating position in this new market, being the major supplier of batteries made using Lithium as the power store.
Then along came Elon Musk. The first Tesla cars, the initial roadster and early models of the series 1 and 2 sedans used what was in effect just large-scale Panasonic batteries. Individual units were linked together with cooling tubes assembled into the pack to dissipate the heat generated by the lithium, which otherwise led to spectacular fires.
Musk in collaboration with Panasonic envisaged a ‘gigafactory’ in Nevada that would supply the packs. As has become a pattern, Panasonic found the task of working with Musk all too much, and were bought out. However, to the point, an essential part of a lithium battery is a range of rare minerals, amongst them Cobalt.
The Democratic Republic of Congo (DRC) hardly democratic, holds almost all the worlds known reserves of Cobalt. Rapid development was inevitable, as was the corruption of local power brokers, and the human rights blindness of the major corporations. Cobalt is a dangerous material, yet much of it is mined by kids in holes with a pick and shovel, dying like flies. There is a registration process designed to monitor and outlaw these practices, but they are useless.
The challenge of replacing Cobalt is therefore the focus of much scientific attention. It is the chemistry of batteries that will deliver a power to weight ratio that will guarantee longer charge life, in everything from your phone to your car, and all the other uses to which Lithium batteries are suddenly being placed.
The world as a choice of three strategies, which should be mutually exclusive:
-
- Find an alternative to cobalt, and quickly.
- Find alternative sources of Cobalt, leaving the DRC out of the picture.
- Internationally strengthen and enforce the existing regulations on the mining and processing of Cobalt to remove the incentive for the current corruption and exploitation that occurs.
The first two options are clearly the best. However, the challenge of replacing Cobalt requires a scientific breakthrough that while probable, is yet to be made, and the DRC remains the primary supplier. The third option seems to be beyond our joint capability.
The first to find and commercialise a solution will reap the rewards.
