Lithium-ion batteries are ubiquitous today – from electric cars to smartphones. But that does not mean that they are the best solution for all application areas. University of Technology Vienna (TU Wien) researchers have now developed an oxygen-ion battery<\/a> that offers some important advantages, the institution announced in a press release<\/a>. Although it does not allow for quite as high energy densities as the lithium-ion battery, its storage capacity does not decrease irrevocably over time: it can be regenerated and thus may enable an extremely long service life.<\/p>\n\n\n\n

In addition, oxygen-ion batteries can be produced without rare elements and are made of incombustible materials. The oxygen-ion battery could be an excellent solution for large energy storage systems, for example to store electrical energy from renewable sources. <\/p>\n\n\n

This salt battery revolutionizes renewable energy storage<\/div>
If it were up to mechanical engineer Jelle Houben, every household in the near future will have a device the size of a large refrigerator filled with salt tablets. The energy stored in this device can be used to heat our homes, and when the battery is empty, it can be recharged using renewable energy. <\/div><\/div><\/div>\n\n\n

Ceramic materials as a new solution<\/h2>\n\n\n\n

\u201cWe have had a lot of experience with ceramic materials that can be used for fuel cells for quite some time,\u201d says Alexander Schmid TU Wien. \u201cThat gave us the idea of investigating whether such materials might also be suitable for making a battery.\u201d<\/p>\n\n\n\n

The ceramic materials that the TU Wien team studied can absorb and release doubly negatively charged oxygen ions. When an electric voltage is applied, the oxygen ions migrate from one ceramic material to another, after which they can be made to migrate back again, thus generating electric current.<\/p>\n\n\n\n

\u201cThe basic principle is actually very similar to the lithium-ion battery,\u201d says Professor J\u00fcrgen Fleig. \u201cBut our materials have some important advantages.\u201d Ceramics are not flammable \u2013 so fire accidents, which occur time and again with lithium-ion batteries, are practically ruled out. In addition, there is no need for rare elements, which are expensive or can only be extracted in an environmentally harmful way.<\/p>\n\n\n\n

\u201cIn this respect, ceramic materials are a great advantage because they can be adapted very well,\u201d says Tobias Huber. \u201cYou can replace certain elements that are difficult to obtain with others relatively easily.\u201d The battery prototype still uses lanthanum \u2013 an element that is not exactly rare but not completely common either. But even lanthanum is to be replaced by something cheaper, and research into this is already underway. Cobalt or nickel, which are used in many batteries, are not used at all.<\/p>\n\n\n

Battery invention from Delft lab can extend battery service life<\/div>
The advancement of batteries is important for the energy transition. Now, Marnix Wagemaker, Dutch professor of electrochemical energy storage, and his colleagues have increased the chaos in a battery by mixing five salts together.<\/div><\/div><\/div>\n\n\n

A long lifespan<\/h2>\n\n\n\n

But perhaps the most important advantage of the new battery technology is its potential longevity: “In many batteries, you have the problem that at some point the charge carriers can no longer move,” says Alexander Schmid. “Then they can no longer be used to generate electricity, the capacity of the battery decreases. After many charging cycles, that can become a serious problem.”<\/p>\n\n\n\n

The oxygen-ion battery, however, can be regenerated without any problems: If oxygen is lost due to side reactions, then the loss can simply be compensated for by oxygen from the ambient air.<\/p>\n\n\n\n

Not for phones or EVs but for storage<\/h2>\n\n\n\n

The new battery concept is not intended for smartphones or electric cars, because the oxygen-ion battery only achieves about a third of the energy density that one is used to from lithium-ion batteries and runs at temperatures between 200 and 400 \u00b0C. The technology is, however, extremely interesting for storing energy.<\/p>\n\n\n\n

“If you need a large energy storage unit to temporarily store solar or wind energy, for example, the oxygen-ion battery could be an excellent solution,” says Alexander Schmid. “If you construct an entire building full of energy storage modules, the lower energy density and increased operating temperature do not play a decisive role. But the strengths of our battery would be particularly important there: the long service life, the possibility of producing large quantities of these materials without rare elements, and the fact that there is no fire hazard with these batteries.”<\/p>\n","protected":false},"author":2583,"featured_media":492945,"template":"views\/single-selected.blade.php","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[42],"tags":[4462,130014,25325,130016,79044,28107],"location":[28214],"internal_archives":[],"class_list":["post-441718","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-sustainability-nl","tag-batterij","tag-ceramic","tag-electricity","tag-oxygen-ion-battery","tag-storage","tag-tu-wien","location-austria"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2023\/03\/csm_Houben-Banner-image_9027452bde.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/francesco-morelli\/","display_name":"Francesco Morelli"},"relative_dates":{"created":"Posted 3 years ago","modified":"Updated 3 years ago"},"absolute_dates":{"created":"Posted on April 2, 2023","modified":"Updated on April 2, 2023"},"absolute_dates_time":{"created":"Posted on April 2, 2023 11:03 am","modified":"Updated on April 2, 2023 11:03 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Sustainability<\/a>"],"unlinked":["Sustainability<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["batterij<\/a>","ceramic<\/a>","electricity<\/a>","oxygen-ion battery<\/a>","storage<\/a>","TU Wien<\/a>"],"unlinked":["batterij<\/span>","ceramic<\/span>","electricity<\/span>","oxygen-ion battery<\/span>","storage<\/span>","TU Wien<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_64241ec4c8435<\/a>"],"unlinked":["pll_64241ec4c8435<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Austria<\/a>"],"unlinked":["Austria<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/441718","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2583"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/492945"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=441718"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=441718"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=441718"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=441718"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=441718"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
