The problem is that the basic battery design hasn't changed since Sony released its rechargeable lithium-ion (li-ion) cell way back in 1991. The li-ion 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.

Chemical functionalization of silicon oxide (SiO2) surfaces with silane molecules is an important technique for a variety of device and sensor applications. Quality control of self-assembled monolayers (SAMs) is difficult to achieve because of the lack of a direct measure for newly formed interfacial Si−O bonds. Herein we report a sensitive measure of the bonding interface between the SAM ...

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.
