The present invention addresses the problem of providing: an electrolyte that can be used to produce a power storage device and has an excellent balance between solubility in organic solvents (non-aqueous solvents), charge/discharge efficiency, 10 C. resistance value, cycle characteristics (volume change rate, capacity retention rate, resistance change rate), and high-temperature characteristics; a reinforcing agent; an electrolyte solution; a power storage device produced using the same; and a method for producing a lithium boron fluoride complex compound and a lithium complex compound for an electrolyte or a reinforcing agent. This electrolyte for a power storage device contains a lithium boron fluoride complex compound having a specific substituent.

Pharmaceutical compositions and methods of their use are provided for reducing inflammation in a subject, blocking leukocyte recruitment, inhibiting tumor metastasis, treating sepsis and preventing/reducing acute kidney injury.
