WebHerein, a nonflammable phosphate-based localized high-concentration electrolyte composed of lithium difluoro (oxalato)borate/dimethyl methyl phosphonate/1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether (LiDFOB–DMMP/HFE) is proposed to improve the safety and reversibility of high-voltage LMBs simultaneously. WebMoreover, a Li-metal battery with thick NCM90 cathode (≈ 15 mg cm −2) and thin Li-metal anode (≈ 50 µm) (N/P ≈ 3), also reveals stable cycling performance under 4.4 V. And a 2.2 Ah NCM90/Li pouch cell can simultaneously possess prominent safety with stably passing the nail penetration test, and high gravimetric energy density of 470 Wh kg −1 at 4.4 V.
