That compares with the previous record of about 1.83% for perovskite-based betavoltaic cells.<\/p>\n\n\n\n<p>Betavoltaic batteries generate electricity from beta particles released during radioactive decay and are seen as a potential alternative to lithium-ion batteries, which face limits on lifespan, safety and charging requirements. They are particularly attractive for applications in space exploration, medical implants and autonomous systems where long-term, maintenance-free power is critical.<\/p>\n\n\n\n<p>The DGIST team used carbon-14 nanoparticles as a radiation source and perovskite materials as absorbers. Working with Yonsei University\u2019s Professor Jong Hyeok Park, the researchers applied methylammonium chloride additives and an isopropanol-based antisolvent process to improve crystal growth and reduce defects. The process enabled an \u201celectron avalanche\u201d effect, generating about 400,000 electrons per beta particle.<\/p>\n\n\n\n<p>The battery maintained stable output for more than 15 hours of continuous operation, surpassing comparable international studies published in <em>Nature<\/em> in 2024, DGIST said.<\/p>\n\n\n\n<p>\u201cThis study has overcome the low efficiency limitations of conventional betavoltaic batteries by utilizing perovskite materials and empirically achieved high efficiency exceeding 10%,\u201d In said in a statement. He added that follow-up research would focus on commercialization for industries requiring energy self-sufficiency.<\/p>\n\n\n\n<p>The work was supported by South Korea\u2019s Ministry of Science and ICT, the National Research Foundation of Korea and other national research programs. Findings were published in the journal <em>Carbon Energy<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SEOUL, Feb 6 &#8211; A South Korean research team has achieved a major advance in betavoltaic battery technology, developing a perovskite-based device with more than six times the efficiency of previous models, DGIST said on Friday.<\/p>\n","protected":false},"author":2,"featured_media":35496,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[121],"tags":[],"class_list":["post-35495","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-physics"],"featured_image_urls":{"full":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research.webp",1426,720,false],"thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-200x200.webp",200,200,true],"medium":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-675x341.webp",675,341,true],"medium_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-768x388.webp",750,379,true],"large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-1100x555.webp",750,378,true],"1536x1536":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research.webp",1426,720,false],"2048x2048":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research.webp",1426,720,false],"ultp_layout_landscape_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-1200x720.webp",1200,720,true],"ultp_layout_landscape":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-870x570.webp",870,570,true],"ultp_layout_portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-600x720.webp",600,720,true],"ultp_layout_square":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-600x600.webp",600,600,true],"newspaper-x-single-post":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-760x490.webp",760,490,true],"newspaper-x-recent-post-big":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-550x360.webp",550,360,true],"newspaper-x-recent-post-list-image":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-95x65.webp",95,65,true],"web-stories-poster-portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-640x720.webp",640,720,true],"web-stories-publisher-logo":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-96x96.webp",96,96,true],"web-stories-thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2026\/02\/dgist-research-150x76.webp",150,76,true]},"author_info":{"info":["RevoScience"]},"category_info":"<a href=\"https:\/\/www.revoscience.com\/en\/category\/news\/physics\/\" rel=\"category tag\">Physics<\/a>","tag_info":"Physics","comment_count":"0","_links":{"self":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/35495","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/comments?post=35495"}],"version-history":[{"count":2,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/35495\/revisions"}],"predecessor-version":[{"id":35500,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/35495\/revisions\/35500"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media\/35496"}],"wp:attachment":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media?parent=35495"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/categories?post=35495"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/tags?post=35495"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
