As the entire world continues to move toward renewable energy sources and vehicles that produce little or no carbon emissions, the demand for viable battery technology is increasing. This is mainly due to the fact that renewable energy needs to be efficiently stored for future use. Similarly, hybrid and electrical vehicles will require batteries that are capable of efficiently storing power that will allow those vehicles to remain powered for longer. These batteries must also be safer and cheaper to produce than they currently are, which is why there is a major effort to improve lithium-ion battery technology for the future. Unfortunately, there are still quite a few obstacles to overcome in this technological field.
