Abstract
At present, mobile energy storage technology (mainly batteries) is still far from satisfactory. For instance, the specific energy of gasoline (~12,432 Wh/kg) is hundreds of times that of a mass-market battery (20-200 Wh/kg) . Quite unlike the computational power predicted by Moore's law, the improvement in battery energy density is much slower, basically following a linear trend. In addition to energy density, battery reliability, weight, and cost are also major impediments to the widespread use of electronic devices (e.g., cellphones, wearable devices, and medical implants) and electric vehicles (EVs).
