The problem is that the basic battery design hasn''t changed since Sony released its rechargeable lithiumion (liion) cell way back in 1991. The liion is a great battery. It powers most of our devices, as well as the burgeoning electric car industry. But you''re still talking about a technology that is nearly 30 years old.

3. Australia. Mine production: 5,100 MT. Australia saw a small increase in cobalt production from 2018 to 2019, with output rising from 4,880 MT to 5,100 MT.

The zinc ore is treated with sulphuric acid. The zinc sulphate solution which is obtained as a result of it is then electrolyted. In the electrolytic tank, the cathodes are of aluminium and the anodes are of lead. The current density is kept 1000 A/m 2 and zinc is deposited on cathode. The energy consumption is about 3000 to 5000 KWH per tonne.
