IBMz New and Greener Battery
“The problems with the design of current
battery technologies like lithium-ion are well known, we just tend to turn a
blind eye when it means our smartphones can run for a full day without a
charge. In addition to lithium, they require heavy metals like cobalt,
manganese, and nickel which come from giant mines that present hazards to the
environment, and often to those doing the actual mining. These metals are also
a finite resource, and as more and more devices and vehicles switch to battery
power, their availability is going to decrease at a staggering pace.”
So an entirely new battery design is
needed. IBM has come up with one. See:
