A collaborative research team from the Universit\u00e9 de Montr\u00e9al and Concordia University has unveiled a breakthrough organic molecule that could solve the intermittency challenges of renewable energy. Dubbed “AzoBiPy” (formally 4,4\u2032-hydrazobis(1-methylpyridinium)), the molecule is designed for use in aqueous organic redox flow batteries (AORFBs) \u2014 a safer, non-flammable alternative to lithium-ion systems. <\/p>\n

The findings \u2014 published in the Journal of the American Chemical Society \u2014 highlight AzoBiPy’s ability to undergo a reversible two-electron transfer. While most organic posolyte (positive electrolyte) molecules only exchange a single electron, AzoBiPy doubles this capacity. <\/p>\n

In laboratory tests, the molecule demonstrated a high volumetric specific capacity of 47.1 Ah\/L and exceptional solubility in water. <\/p>\n

Stability has long been the weakness of organic storage, but AzoBiPy set a new benchmark. During a 70-day trial involving 192 charge-discharge cycles, the molecule retained nearly 99% of its initial capacity, losing a mere 0.02% per day. Researchers say this performance is almost unprecedented for an organic compound, suggesting it could store energy collected in the summer to heat homes throughout the winter. <\/p>\n

The practical potential of this technology was highlighted during a 2024 live demonstration at a departmental holiday event. A prototype flow battery, using only two tablespoons of the aqueous solution per tank, successfully powered a set of Christmas tree lights for eight hours. <\/p>\n

Renewability-wise, while commercial flow batteries rely mostly on vanadium, AzoBiPy is composed of abundant elements like carbon, nitrogen, and hydrogen. The team is currently exploring bio-based versions derived from wood and food waste. With patent applications underway, the researchers expect this class of compounds to reach wide-scale adoption within the next decade or so.<\/p>\n

I have always been fascinated by technology and digital devices my entire life and even got addicted to it. I have always marveled at the intricacy of even the simplest digital devices and systems around us. I have been writing and publishing articles online for about 6 years now, just about a year ago, I found myself lost in the marvel of smartphones and laptops we have in our hands every day. I developed a passion for learning about new devices and technologies that come with them and at some point, I asked myself, “Why not get into writing tech articles?” It is useless to say I followed up the idea \u2014 it is evident. I am an open-minded individual who derives an infinite amount of joy from researching and discovering new information, I believe there is so much to learn and such a short life to live, so I put my time to good use \u2014 learning new things. I am a ‘bookworm’ of the internet and digital devices. When I am not writing, you will find me on my devices still, I do explore and admire the beauty of nature and creatures. I am a fast learner and quickly adapt to changes, always looking forward to new adventures.<\/p>\n","protected":false},"excerpt":{"rendered":"A collaborative research team from the Universit\u00e9 de Montr\u00e9al and Concordia University has unveiled a breakthrough organic molecule…\n","protected":false},"author":2,"featured_media":463584,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[189407,214,49,48,11290,215,207,213,206,189406,216,212,208,209,61,211,210,68185,64911],"class_list":["post-463583","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-alternative-energy-storage","tag-benchmarks","tag-ca","tag-canada","tag-concordia-university","tag-graphics-card","tag-laptop","tag-netbook","tag-notebook","tag-organic-molecule","tag-processor","tag-reports","tag-review","tag-reviews","tag-technology","tag-test","tag-tests","tag-universite-de-montreal","tag-university-of-montreal"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/463583","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=463583"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/463583\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/463584"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=463583"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=463583"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=463583"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
