▎ 摘　　要

NOVELTY - The electrical energy storage device has a cathode (14) and an anode (26). One of the anode and cathode comprises separated inner shells or outer shells of a legume or nut treated with a macroscopically open structure composed of graphene or of carbon nanosheets. The inner shells are primarily composed of lignin. USE - Electrical energy storage device for high energy and high power delivery. Used as one of hybrid ion capacitor (claimed), sodium ion capacitor, lithium ion capacitor, sodium ion battery, or lithium ion battery suited for consumer electronics, automotive, aerospace and stationary markets. ADVANTAGE - During electrochemical testing the open architecture of peanut shell nanosheet carbon (PSNC) will allow full access of the electrolyte to the active surfaces, minimizing high rate diffusional losses through the liquid. Overall the PSNC 3-800 electrode offers the best performance, which may be attributed to its optimum combination of oxygen content, surface area and mesopore content, the latter becoming critical at high scan rates. Improves the electrolyte access to the bulk of the material and reduces the solid-state diffusion distances due to a lower effective sheet thickness. Optimizing device performance consists of achieving the widest possible working voltage window without decomposing the electrolyte, while maximizing the capacity of both electrodes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for an electrical energy storage device. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of an energy storage device. Cathode (14) Anode (26) Electrolyte (32) Separator (34) Circuit flow elements (38)
