MIBAMIN: Research and study of flow microbatteries for application in photovoltaic microinverters

Call for aid for the completion of industrial doctorates 2017 of the Community of Madrid (Ref: IND2017/AMB-7719).

Flow batteries are considered an alternative to Lithium-ion batteries for stationary applications due to their longer lifetime, better cycle life and larger potential of cost reduction. So far the trend in this type of batteries has been to scale them up to reach power and capacities adequate for providing services to renewable generation plants, i.e., in the range of MW and MWh. In this research work the main challenge is to move backwards by downscaling the technology so that to take advantage of the performance improvements expect from microfluidics and of the tremendous potential of industrial manufacturing of microelectronic devices.

This is an industrial research project aimed at obtaining a flow battery with power and capacity able to be implemented in a photovoltaic microinverter. The device is called microbattery not for the rated power or energy but for the technologies involved: micromechanics, microfluidics, microelectronics and micromachining.
