In Situ Forming a Black Phosphorene Mixed Ion/Electron Conductor Layer by External Pressure without Binder for Anode-Free Li Metal Batteries.

Anode-free Li metal batteries are an excellent choice for developing the next generation of high-energy-density battery systems. However, due to poor chemical compatibility between the current collector and electrolyte interface, the Li electrodeposition on current collectors faces a huge challenge of rapid capacity degradation in anode-free Li metal batteries. Herein, a strategy for modifying an ultrathin black phosphorene (BP) mixed ion/electron conductor interface layer on the surface of a current collector by relying on pressure is proposed.

Integral Histogram with Random Projection for Pedestrian Detection.

In this paper, we give a systematic study to report several deep insights into the HOG, one of the most widely used features in the modern computer vision and image processing applications. We first show that, its magnitudes of gradient can be randomly projected with random matrix. To handle over-fitting, an integral histogram based on the differences of randomly selected blocks is proposed.
