Rechargeable battery high-performance, research goes on as well
A new type of battery that combines the capacity of a negative and a negative resistance within the same cell, allowing it to auto-load without losing energy, which has important implications for the long-term preservation and for better power output. These batteries can be used in devices such as flashing lights, beeps, electronic, oscillators, voltage-controlled, inverter, switching power supplies, digital converters, and generators of functions, and, finally, for technologies related to the most advanced computer.

In the "Applied Physics Reviews", of AIP Publishing, Helena Braga and his colleagues of the University of Porto in Portugal and the University of Texas at Austin, report having made a battery that is very simple to do with two different metals as electrodes and an electrolyte of lithium or glass of sodium to between them.

"The electrolyte of the glass that we have developed was rich in lithium, and then I thought we could create a battery in which the electrolyte would have powered both electrodes with a lithium-ion battery, charging and discharging without the need of lithium metal," said Braga. Our electrochemical cells in principle are more simple of batteries, all are self-organization, which is the substance of life," said Braga. "Having the negative electrode made of the same material of the positive ions of the electrolyte," added Braga. "it gives rise to a device that you load alone without the processes of self-cycling - increasing the energy stored in it - as opposed to the natural degradation of the electrochemical process, which decreases the stored energy with the dissipation of the heat. May have applications in devices for energy storage, such as batteries and capacitors, and can substantially improve their autonomy".
