To every investor; There has been huge investment been made to the Battery technology, to develop sustainable future with renewable energy.... So we all are assuming that battery technology can be 811 or  622 or what else.

The factors to consider:

How cars batteries can be charged in similar time; like when refueling the car.  (i.e, 2 min to fully charge the battery). Which should support at least 500km charge free run. Can they achieve; if so all other technology will be superseded by this technology. Yet to be developed. huge investment being made....

Alternative:

2. Can the car battery can be charged by Solar supply during day as well as due to car movement, (wind energy)?
3. Can the technology can be developed to auto recharge the battery, i.e due to car movement, mechanical energy is converted into DC electrical energy for battery storage.
4. Can the devices in petrol station replaced to accommodate the charging stations? how cost effective; how long will it take to fully charge the battery.
5. Can charging station can be installed in each car park. how cost effective.
6. Cost of these charging stations.

A good battery must hold the charge for longer time; must charge quicker; as well as a battery which can provide higher safety, reliability, maintainability targets will be the preferred choice by the car manufacturers. So, given the above statement; I believe Cobalt can not be eliminated in the battery manufacturing process of Lithium Ion batteries.

Please do sell; so I can buy them @ .016 cent.
