An energy storage device includes a nano-structured cathode. The cathode includes a conductive substrate, an underframe and an active layer. The underframe includes structures such as nano-filaments and/or aerogel. The active layer optionally includes a catalyst disposed within the active layer, the catalyst being configured to catalyze the dissociation of cathode active material.

Lithium-ion battery anode including preloaded lithium

A three-dimensional (3D) inkjet printer is configured to build up an object by printing a series of layers and stacking them to form the object. In order to speed printing, drying of each layer is accelerated by using a pressure differential to extract liquid vehicle from the ink, and by moving the printed layer away from the inkjet print heads before drying so that the inkjet print heads may print the next layer. The dried printed layer may also be conditioned and/or cured. Dried printed layers are stacked at a build station to assemble the finished object.

Jetted material printer with pressure-assisted fluid extraction

A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Liintercalation medium. Highly reversible Liintercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.
