A team of researchers from the Technion \u2013 Israel Institute of Technology has developed a proof-of-concept for a\u00a0novel rechargeable silicon (Si) battery, as well as its design and architecture that enables Si to be reversibly discharged and charged, writes Technion in a press release<\/a>.<\/p>\n\n\n\n

Led by Professor Yair Ein-Eli of the Faculty of Materials Science and Engineering, the team proved via systematic experimental works of the graduate student, Alon Epstein and theoretical studies of Dr. Igor Baskin, that Si is dissolved during the battery discharge process, and upon charging, elemental Si is deposited. Several discharge-charge cycles were achieved, utilizing heavy doped n-type Si wafer anodes and specially designed hybrid based ionic liquid electrolytes, tailored with halides (Bromine and Iodine), functioning as conversion cathodes.<\/p>\n\n\n\n

This breakthrough could pave the way towards an enrichment of the battery technologies available in the energy storage market, with the technology potentially easing stress on the ever-growing market and serving the increasing demand for rechargeable batteries.<\/p>\n\n\n\n

Developments leading to this breakthrough<\/strong><\/h3>\n\n\n\n

The increased demand for sustainable energy sources prompted the scientific community to focus on battery research capable of storing large scale grid energy in a manageable and reliable manner. Moreover, the rising demand of the EV industry, which mainly relies on current Li-ion battery (LIBs) technology is expected to strain current Li production and divert it from more widespread use in portable consumer electronics. Currently, no technology has proven to be competitive enough to displace LIBs. Metals and elements capable of delivering multi-electrons during their oxidation process have been the focus of the research community for a long time due to their associated high specific energy densities.<\/p>\n\n\n

New sensors help improve battery life in electric cars<\/div>
Batteries are the single most costly part of electric vehicles (EVs). Their range is the main pressing concern for those who are considering buying an EV. Consequently, being able to monitor their status as well as protect them can improve safety. To make sure that the driving range doesn\u2019t lessen over time, new technologies can now check the battery\u2019s status. <\/div><\/div><\/div>\n\n\n

Magnesium, calcium, aluminum and zinc received much attention as potential anode materials with varied levels of progress; yet none has managed to revolutionize the energy storage industry beyond LIBs, as all of these systems suffer from poor kinetic performance to lack of cell stability, and therefore, much is left to be explored. Silicon (Si), as the second most abundant element on earth\u2019s crust (after oxygen), was left relatively unexplored despite a high energy density of 8.4 kWh kg-1 on par with metallic Li 11.2 kWh kg-1; Si possesses stable surface passivation, low conductivity (dependent on the doping levels), and, until now, no established rechargeable cell chemistry comprising elemental Si as an active anode has been reported, outside LIB alloying anode.<\/p>\n\n\n\n

In the past decade several publications (initiated originally in 2009 by Prof. Ein-Eli) reported the incorporation of active Si anodes in primary, non-rechargeable air-battery designs. Thus, despite its high abundance and ease of production, the possibility of using Si as an active multivalent\u00a0rechargeable anode\u00a0was never explored, until the team\u2019s recent breakthrough.<\/p>\n","protected":false},"author":2084,"featured_media":516789,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[26049],"tags":[25751,128164,67445],"location":[66847],"internal_archives":[],"class_list":["post-387787","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-mobility","tag-batteries","tag-silicon-battery","tag-technion-israel-institute-of-technology","location-israel"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/07\/continental_pp_current-sensor-module.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on July 20, 2022","modified":"Updated on July 20, 2022"},"absolute_dates_time":{"created":"Posted on July 20, 2022 4:00 pm","modified":"Updated on July 20, 2022 4:00 pm"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Mobility<\/a>"],"unlinked":["Mobility<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["batteries<\/a>","silicon battery<\/a>","Technion Israel Institute of Technology<\/a>"],"unlinked":["batteries<\/span>","silicon battery<\/span>","Technion Israel Institute of Technology<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":[],"unlinked":[],"slug":"post_translations","name":""},"location":{"linked":["Israel<\/a>"],"unlinked":["Israel<\/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\/387787","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\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/516789"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=387787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=387787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=387787"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=387787"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=387787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
