Storage Capacity: Lead acid batteries come in a variety of voltages and sizes, but can weigh 2-3x as much as lithium iron phosphate per kilowatt hour, depending on battery quality. Battery Cost: Lead acid batteries are about 75% cheaper than their lithium iron phosphate equivalent, but don''t be fooled by the lower cost.
Electrical Energy Storage is a process of converting electrical energy into a form that can be stored for converting back to electrical energy when needed (McLarnon and Cairns, 1989; Ibrahim et al., 2008 ). In this section, a technical comparison between the different types of energy storage systems is carried out.
1.
