Lithium Ion Capacitor

Lithium-ion capacitors (LICs) have been widely explored for energy storage. Nevertheless, achieving good energy density, satisfactory power density, and stable cycle life is still challenging. For this study, we fabricated a novel LIC with a NiO-rGO composite as a negative material and commercial activated carbon (AC) as a positive material for energy storage. The NiO-rGO//AC system utilizes NiO nanoparticles uniformly distributed in rGO to achieve a high specific capacity (with a current density of 0.5 A g−1 and a charge capacity of 945.8 mA h g−1) and uses AC to provide a large specific surface area and adjustable pore structure, thereby achieving excellent electrochemical performance. In detail, the NiO-rGO//AC system (with a mass ratio of 1:3) can achieve a high energy density (98.15 W h kg−1), a high power density (10.94 kW kg−1), and a long cycle life (with 72.1% capacity retention after 10,000 cycles). This study outlines a new option for the manufacture of LIC devices that feature both high energy and high power densities.

First Time

In the 1970s and 1980s, Los Angeles audiences saw Soviet defectors Mikhail Baryshnikov, Alexander Godunov, Natalia Makarova, and Rudolf Nureyev in the prime of their careers at the Hollywood Bowl, The Dorothy Chandler Pavilion and the Greek Theater. Dance photographer Donald Dale Bradburn, a local Southern California dancer describes his behind-the-scenes access to these dancers in this interview. Perfectly positioned as Dance Magazine’s Southern California correspondent, Bradburn offers a candid appraisal of the Southern California appeal for such high-power Russian artists as well as their impact on the arts of Los Angeles. An intimate view of Russian dancers practicing their craft on Los Angeles stages, Bradburn’s interview is illustrated by fourteen of his photographs, published for the first time in this issue of Experiment.
