Aspects of the invention are directed to a container comprising a tub, a basket, and a lid. The tub is adapted to hold a liquid and comprises a bottom and a tub sidewall having an upper rim defining an opening in the tub. The basket is disposed on the bottom of the tub and comprises a base and a basket sidewall. The base defines a perimeter, and the basket sidewall runs along at least a portion of this perimeter. The lid contacts the upper rim and comprises a filler piece. The filler piece occupies a volume inside the tub between the base and a plane defined by the upper rim. The container is adapted to hold a sensitive film stack without damage or degradation to the film stack. The container is further adapted to facilitate the easy transfer of the film stack to a new substrate.


The invention provides improved paper-like electrodes and electrode active materials for use in flexible energy storage devices, and methods for preparing such electrodes and materials, as well as flexible energy storage devices fabricated from such electrodes and materials and methods of making such devices. The electrodes and electrode active materials comprise multi-layer high-quality thin carbon films, and the methods comprise the use of a repetitive laminar process to deposit such films directly on polymer separators or electrolyte membranes.

Aspects of the invention are directed to a method for forming a graphene composite structure. Initially, an encapsulating film is formed on a substrate. The encapsulating film comprises graphene. Subsequently, a plurality of particles are deposited on the encapsulating film, and then a temporary layer is deposited on the plurality of active particles and the encapsulating film. The substrate is then removed. Lastly, the temporary layer is also removed so as to cause the plurality of particles to form a cluster that is at least partially encapsulated by the encapsulating film.

Aspects of the invention are directed to a method of forming graphene structures. Initially, a cluster of particles is received. The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.
