1-Propylphosphonic acid cyclic anhydride

Besides LiBOB, other additives have been reported to protect the high voltage cathode and mitigate electrolyte decomposition, including LiDFOB [162], succinic anhydride [66, 122], 1,3-propane sultone [66], tris(hexafluoro- o-propyl) phosphate [127], tris(pentafluorophenyl) phosphine [156], 3-hexylthiophene [3], 1,3-propanediolcyclic sulfate [41], dimethylacetamide [13], triethyl(2-methoxyethyl) phosphonium bis(trifluoromethylsulfonyl)imide [13], glutaric anhydride [16], 4-(trifluoromethyl)-benzonitrile [55], and 1-propylphosphonic acid cyclic anhydride [ 160]. The stmctures of the additives that are not listed in the previous text are shown in Fig. 8.

The cycling performance of graphite/LiNio.5Coo.2Mno.302 battery in the electrolyte with a different content from 0% to 2.0% of 1-propylphosphonic acid cyclic anhydride, cf. Figure 2.16, has been... 

When 0.5% of 1-propylphosphonic acid cyclic anhydride is incorporated into the blank electrolyte, the capacity retention of graphite/LiNio,5Coo,2Mno,302 battery at high voltage after 100 cycles is increased from 79.12% to 91.84%.
