New battery tech
The main technology blocker is the current expensive batteries that raise the cost of electricity storage for car building or for dealing with intermittent wind and solar energies. Also, current batteries require rare components that limit mass production. Scientists and investors are developing new technologies that could achieve the holy grail of cheap batteries.
New battery tech should cope with multiple targets:
-cheap price for storing electricity;
-fast charging for vehicles;
-lightweight for airplanes;
-long life for avoiding costly recycling.
New solutions range from improved lithium based, to supercapacitors or even cheap H2>/span> production for fuelcell tech similar to battery.
