Scientists at TU Wien have made a development by developing an oxygen-ion battery that uses a number of significant benefits. These oxygen-ion batteries could provide an outstanding option for massive energy storage systems, such as those required to hold electrical energy from renewable sources.
Possibly the most essential advantage of the brand-new battery innovation is its prospective longevity: “In numerous batteries, you have the issue that at some point the charge providers can no longer move,” states Alexander Schmid.” If you need a big energy storage unit to temporarily save solar or wind energy, for example, the oxygen-ion battery could be an excellent solution,” states Alexander Schmid. The strengths of our battery would be especially essential there: the long service life, the possibility of producing big amounts of these materials without rare components, and the reality that there is no fire danger with these batteries.”

Researchers at TU Wien (Vienna) have actually established a groundbreaking oxygen-ion battery, which boasts exceptional resilience, gets rid of the requirement for rare components, and resolves the issue of fire threats.
Lithium-ion batteries, while commonplace in todays world– powering everything from electric lorries to smartphones– arent always the optimal option for all applications. Researchers at TU Wien have actually made a development by producing an oxygen-ion battery that provides a number of substantial benefits. While it might not match the energy density of lithium-ion batteries, its storage capacity does not lessen irreversibly over time, making it capable of an exceptionally long life-span as it can be regrowed.
The fabrication of oxygen-ion batteries does not require scarce components and involves non-combustible materials. The innovative battery idea has currently caused a patent application, filed in cooperation with partners in Spain. These oxygen-ion batteries could provide an outstanding option for large-scale energy storage systems, such as those needed to hold electrical energy from renewable sources.
Ceramic materials as a brand-new service
” We have had a lot of experience with ceramic materials that can be used for fuel cells for quite some time,” says Alexander Schmid from the Institute for Chemical Technologies and Analytics at TU Wien. “That gave us the concept of examining whether such materials may also appropriate for making a battery.”
The ceramic products that the TU Wien team studied can absorb and release twice as adversely charged oxygen ions. When an electric voltage is used, the oxygen ions migrate from one ceramic material to another, after which they can be made to migrate back once again, thus producing electrical existing.

” The standard concept is really very comparable to the lithium-ion battery,” states Prof. Jürgen Fleig. Ceramics are not flammable– so fire accidents, which happen time and once again with lithium-ion batteries, are virtually ruled out.
The model of the battery still uses lanthanum– a component that is not exactly unusual but not completely typical either. Cobalt or nickel, which are utilized in lots of batteries, are not used at all.
Jet set period
Possibly the most important benefit of the brand-new battery innovation is its possible durability: “In numerous batteries, you have the issue that at some point the charge providers can no longer move,” states Alexander Schmid. “Then they can no longer be utilized to generate electrical energy, the capability of the battery decreases. After lots of charging cycles, that can become a major problem.”
The oxygen-ion battery, nevertheless, can be regrowed with no issues: If oxygen is lost due to side reactions, then the loss can merely be made up for by oxygen from the ambient air.
The new battery concept is not intended for mobile phones or electrical automobiles, due to the fact that the oxygen-ion battery just attains about a third of the energy density that a person is used to from lithium-ion batteries and performs at temperature levels between 200 and 400 ° C. The innovation is, nevertheless, very interesting for saving energy.
” If you need a large energy storage unit to briefly save solar or wind energy, for instance, the oxygen-ion battery might be an exceptional option,” states Alexander Schmid. “If you construct a whole building full of energy storage modules, the lower energy density and increased running temperature do not play a definitive function. However the strengths of our battery would be especially crucial there: the long life span, the possibility of producing big amounts of these products without unusual components, and the fact that there is no fire danger with these batteries.”
