▎ 摘　　要

NOVELTY - An electrode comprises an electrically conductive, porous aerogel (10) having pores, and an active material (60) covalently and/or physically bonded to the porous aerogel within the pores. The porous aerogel comprises an electrically conductive graphene oxide having functional groups and a polymer covalently and/or physically bonded to the graphene oxide. USE - Electrode is used in battery, fuel cell, electrochemical sensor and ultracapacitor (all claimed). Uses include but are not limited to lithium-ion batteries, flexible batteries, computers, phones, power tools, cars, grid energy storage systems, medical sensors and gas sensors. ADVANTAGE - The electrode has preset ion-conductivity, is highly porous, and provides battery that can retain at least 85% of its capacity after the charge/discharge cycle (C1) for at least 500 additional cycles with improved capacity and capacity retention. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) formation of the electrode, which involves covalently and/or physically bonding to the electrically-conductive graphene oxide, forming the aerogel, and covalently and/or physically bonding the active material to the aerogel; and (2) battery, which comprises at least one electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional schematic view of the active material particle directly bonded to the aerogel. Aerogel (10) Active material (60)
