After charging and then turning off the external input voltage, the energy storage module can effectively sustain the release of ionic drugs. The drug release stops when the external wireless charging is closed and all the electrical energy stored in the supercapacitors is exhausted.
Latent heat/cold stores for pumped-thermal energy storage are experimentally studied. The rated power of the demonstration system is 20 kW and the charge/discharge time is 5 h. The round-trip efficiency of the experimental system achieves up to 0.37. The cumulative stored exergy can reach 11.89 kWh with an exergy efficiency of 0.61.
As for systematic exergy despite the total destruction of thermal energy storage units amounts to 12.25 kWh the maximum exergy efficiency could reach 0.61 simultaneously. 1. Introduction The greenhouse effect owing to heavy use of fossil fuels has kept the Earth warmer than it has been for billions of years .
In particular, the energy storage module is fully made of biodegradable materials while achieving high electrochemical performance (including a high capacitance of 93.5 mF cm −2 and a high output voltage of 1.3 V), and its charge storage mechanism is further revealed by comprehensive characterizations.
