The high cost and scarcity of lithium resources have prompted researchers to seek alternatives to lithium‐ion batteries. Among emerging “Beyond Lithium” batteries, rechargeable aluminum‐ion batteries (AIBs) are yet another attractive electrochemical storage device due to their high specific capacity and the abundance of aluminum. Although the current electrochemical performance of nonaqueous AIBs...
Tin diselenide (SnSe2), as an anode material, has outstanding potential for use in advanced lithium‐ion batteries. However, like other tin‐based anodes, SnSe2 suffers from poor cycle life and low rate capability due to large volume expansion during the repeated Li+ insertion/de‐insertion process. This work reports an effective and easy strategy to combine SnSe2 and carbon nanotubes (CNTs) to form...
An integrated system has been provided with a-Si/H solar cells as energy conversion device, NiCo2O4 battery-supercapacitor hybrid (BSH) as energy storage device, and light emitting diodes (LEDs) as energy utilization device. By designing three-dimensional hierarchical NiCo2O4 arrays as faradic electrode, with capacitive electrode of active carbon (AC), BSHs were assembled with energy density of 16...
