The particulate is formed of a core carbon or graphite particle and a plurality of satellite carbon or graphite particles that are each separately bonded to the core particle wherein the core particle is spherical in shape, slightly elongate in shape with a major axis-to-minor axis ratio less than 2, or fibril in shape, and wherein the satellite particles are disc-, platelet-, or flake-like particles each containing a graphite crystallite with a crystallographic c-axis dimension Lc and a lateral dimension. Preferably, Lc is less than 100 nm and the flake/platelet lateral dimension is less than 1 μm. The core particle may be selected from natural graphite, artificial graphite, spherical graphite, graphitic coke, meso-carbon micro-bead, soft carbon, hard carbon, graphitic fibril, carbon nano-fiber, carbon fiber, or graphite fiber. Preferably, the flat-shaped particles are randomly oriented with respect to one another.

摘要： This invention provides a vehicle powered by a surface-mediated cell (SMC)-based power source, comprising a vehicle frame, at least a wheel supporting the frame or a propeller connected to the frame, a drive unit connected to the wheel or propeller, and a power source electrically connected to the drive unit, wherein the power source contains at least a surface-mediated cell. The vehicle can be a micro-EV (using the SMC for the stop-start function), HEV, plug-in HEV, all-electric vehicle, power-assisted bicycle, scooter, motorcycle, tricycle, automobile, wheelchair, fork lift, golf cart, specialty vehicle, bus, truck, train, rapid-transit vehicle, boat, or air vehicle. The ultra-high power density enables the SMC to provide pulsed power or increased current demands when the vehicle is accelerating or hill-climbing. The SMC also enables the power source to recuperate the braking energy when the vehicle decelerates, brakes, or simply moves down-hill.
