An energy storage system is provided for an electric vehicle. The energy storage system comprises a first energy storage source. The first energy storage source includes an ammonia tank configured to hold ammonia, an ammonia converter configured to receive ammonia from the ammonia tank and convert the received ammonia into hydrogen, and a fuel cell system communicating with the ammonia converter and configured to generate output power from hydrogen that is received from the ammonia converter.

Energy storage systems and ammonia-powered electric vehicles including the same

In the present invention there is provided an MnOelectrode with improved electrochemical properties, and a method of preparation of an electrode, wherein there anode comprises a substrate at least partially coated with MnOnanosheets (MnNSs) forming additive free MnOthin films. The method includes providing MnOnanosheets (MnNSs) suspension with diameters less than 50 nm; printing the MnNSs suspension on substrates to form MnOthin films (MnTFs); and annealing the MnTFs at 260-320&#xb0; C. for at least 100 minutes. Energy storage device comprising the MnOelectrode such as a Na-ion cell, and a Li-ion cell are also described.

MnOanode for Li-ion and Na-ion batteries

In one aspect, the present disclosure relates to an improved method of preparing concentrated MnOink with increased efficiency and cost effectiveness. The method involves mixing KMnOsolution with highly crystalline carbon particles (HCCPs) with average diameters less than 800 nm at 30-60&#xb0; C. for at least 8 hours. The present disclosure further relates to a symmetric supercapacitor device comprising MnOcoated electrodes and a solid state ionic liquid as electrolyte, as well as an interdigital transparent SC (IT-SC) device comprising aqueous MnOink.
