An Ultralow‐concentration and Moisture‐resistant Electrolyte of Lithium Difluoro(oxalato)borate in Carbonate Solvents for Stable Cycling in Practical Lithium‐ion Batteries
The electrolyte concentration not only impacts the battery performance but also affects the battery cost and manufacturing. Currently, most studies focus on high‐concentration (>3 M) or localized high‐concentration electrolytes (~1 M); however, the expensive lithium salt imposes a major concern....

Currently, most studies focus on high‐concentration (>3 M) or localized high‐concentration electrolytes (~1 M); however, the expensive lithium salt imposes a major concern. Most recently, ultralow concentration electrolytes (<0.3 M) have emerged as intriguing alternatives for battery applications, which feature low cost, low viscosity, and extreme‐temperature operation. However, at such an early development stage, many works are urgently needed to further understand the electrolyte properties. Herein, we introduce an ultralow concentration electrolyte of 2 wt % (0.16 M) lithium difluoro(oxalato)borate (LiDFOB) in standard carbonate solvents. This electrolyte exhibits a record‐low salt/solvent mass ratio reported to date, thus pointing to a superior low cost. Furthermore, this electrolyte is highly compatible with commercial Li‐ion materials, forming stable and inorganic‐rich interphases on the lithium cobalt oxide (LiCoO2) cathode and graphite anode. Consequently, the LiCoO2‐graphite full cell demonstrates excellent cycling performance. Besides, this electrolyte is moisture‐resistant and effectively suppresses the generation of hydrogen fluoride, which will markedly facilitate the battery assembly and recycling process under ambient conditions.
We developed an ultra‐low concentration, moisture‐resistant, and environmentally friendly electrolyte of 0.16 M LiDFOB/EC‐DMC, which is fully compatible with commercial battery materials, leading to long cycling performance.</description><identifier>ISSN: 0044-8249</identifier><identifier>EISSN: 1521-3757</identifier><identifier>DOI: 10.1002/ange.202400110</identifier><language>eng</language><publisher>Weinheim: Wiley Subscription Services, Inc</publisher><subject>Cobalt ; Cobalt oxides ; Cycles ; Electrode-Electrolyte Interphase ; Electrolytes ; Graphite ; Hydrogen fluoride ; Lithium ; Lithium compounds ; Lithium Difluoro(oxalato)borate Salt ; Lithium-ion batteries ; Lithium-Ion Battery ; Low cost ; Low-Concentration Electrolyte ; Moisture resistance ; Solvation Structure ; Solvents</subject><ispartof>Angewandte Chemie, 2024-05, Vol.136 (19), p.n/a</ispartof><rights>2024 Wiley‐VCH GmbH</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c1170-6b996679cfaeb203a5e950483fe46649b90f5b036243574ec6a55406d512630a3</cites><orcidid>0000-0002-1687-6643 ; 0000-0002-9950-5687</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fange.202400110$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fange.202400110$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1417,27924,27925,45574,45575</link.rule.ids></links><search><creatorcontrib>Liu, Zhishan</creatorcontrib><creatorcontrib>Hou, Wentao</creatorcontrib><creatorcontrib>Tian, Haoran</creatorcontrib><creatorcontrib>Qiu, Qian</creatorcontrib><creatorcontrib>Ullah, Irfan</creatorcontrib><creatorcontrib>Qiu, Shen</creatorcontrib><creatorcontrib>Sun, Wei</creatorcontrib><creatorcontrib>Yu, Qian</creatorcontrib><creatorcontrib>Yuan, Jinliang</creatorcontrib><creatorcontrib>Xia, Lan</creatorcontrib><creatorcontrib>Wu, Xianyong</creatorcontrib><title>An Ultralow‐concentration and Moisture‐resistant Electrolyte of Lithium Difluoro(oxalato)borate in Carbonate Solvents for Stable Cycling in Practical Lithium‐ion Batteries</title><title>Angewandte Chemie</title><description>The electrolyte concentration not only impacts the battery performance but also affects the battery cost and manufacturing.
