摘要： An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode. At least one of the electrodes can include an electrode film prepared by a dry process. The electrode film, the electrode and/or the separator can comprise a salt, improved porosity, increased density, be prelithiated, and/or a foam. Process and apparatuses used for fabricating the electrode and/or electrode film are also described.

摘要： Apparatuses and methods for forming an electrode film mixture are described. An apparatus for forming an electrode film mixture can have a first source including a solution comprising a polymer, for example, polytetrafluoroethylene and a critical or supercritical fluid, for example, supercritical carbon dioxide, a second source including a second component of the electrode film mixture, a mixer configured to receive the solution and the second component and to form a slurry comprising the solution and the second component. The apparatus can include a decompressor configured to receive the slurry and decompress the slurry to vaporize the critical or supercritical fluid and precipitate dry polymer.

摘要： An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode and/or electrode includes an electrode film having a super-fibrillized binder material and carbon. The electrode film can have a reduced quantity of the binder material while maintaining desired mechanical and/or electrical properties. A process for fabricating the electrode film may include a fibrillization process using reduced speed and/or increased process pressure such that fibrillization of the binder material can be increased. The electrode film may include an electrical conductivity promoting additive to facilitate decreased equivalent series resistance performance. Increasing fibrillization of the binder material may facilitate formation of thinner electrode films, such as dry electrode films.

摘要： An energy storage device can include a cathode and an anode, where at least one of the cathode and the anode are made of a polytetrafluoroethylene (PTFE) composite binder material including PTFE and at least one of polyvinylidene fluoride (PVDF), a PVDF co-polymer, and poly(ethylene oxide) (PEO). The energy storage device can be a lithium ion battery, a lithium ion capacitor, and/or any other lithium based energy storage device. The PTFE composite binder material can have a ratio of about 1:1 of PTFE to a non-PTFE component, such a PVDF, PVDF co-polymer and/or PEO.
