(2,5-Dimethoxy-1,4-phenylene)bis(di-i-propylphosphine oxide) Usage And Synthesis

Uses

Redox Shuttles for Lithium Ion Batteries

1. Provides a long term intrinsic overcharge protection of lithium-ion batteries.
2. Maintains the safe operation of lithium-ion batteries.
3. Highly-soluble in conventional non-aqueous, carbonate based electrolytes.
4. Increases battery long-term stability and oxidation potential.

1. ANL-RS5 (abbreviated BPDB) exhibits a reversible redox potential of about 4.5V vs Li/Li+ (1.2 M LiPF6 in 3:7 wt/wt mixture of ethylene carbonate and ethyl methyl carbonate). 
2. Provides stable overcharge protection for 4V MCMB (mesocarbon microbead)/LMO (LiMn2O4) cells delivering 95 cycles of 100% overcharge at room temperature.
