Original sentence: In 2009, they made synthetic protocells which can provide about a twentieth of the energy density of a lead-acid battery, and an energy conversion efficiency of 10%.In 2016, Hao Sun and colleagues described a family of electric eel-mimicking devices that serve as high output voltage electrochemical capacitors.
Quantified sentence: In 2009, they made synthetic protocells which can provide about a twentieth of the energy density of a lead–acid battery, and a small energy conversion efficiency. In 2016, Hao Sun and colleagues described a family of electric eel-mimicking devices that serve as high output voltage electrochemical capacitors.
