The research team of the University of Technology in Austria has recently created a charged oxygen ion battery with oxide ceramics. The cost is relatively low and the service life is long. It is suitable for occasions that require large -scale storage of electrical energy.
Some oxide ceramics can transmit ions and electronics, and have been used to make power generation devices such as fuel cells. The school's research team uses such hybrid conductive ceramic materials as electrodes to develop batteries for storage energy. It relies on oxygen ions to move back and forth between electrodes to generate current, just like the motion of lithium ion battery depends on lithium ions.
This oxygen ion battery does not contain combustible materials, eliminating the risk of fire. The loss of oxygen during use can be added directly from the air by the auxiliary electrodes, so that the power storage capacity can be "regenerated" to achieve a long service life.
Researchers said that the energy density of this new battery is lower than that of lithium -ion batteries and is not suitable for products such as smartphones and electric vehicles, but its power storage capacity can maintain long -term decline and have practical value for industrial energy storage. Electricity generated by power generation. In addition, the battery does not need to use rare and expensive materials. At present, the prototype battery manufactured by the research team contains rare earth elements. It is expected to replace it with cheaper materials in the future. Related research has been in progress.
