In their application to green technology, batteries are systems for storing electrical power for use in vehicles or to provide temporary power to compensate for intermittency of generation. With limited ability to store large amounts of energy, they are the weak link in all-electric vehicle applications but are needed to replace disappearing energy supplies.
