摘要： Porous electrodes in which the porosity has a low tortuosity are generally provided. In some embodiments, the porous electrodes can be designed to be filled with electrolyte and used in batteries, and can include low tortuosity in the primary direction of ion transport during charge and discharge of the battery. In some embodiments, the electrodes can have a high volume fraction of electrode active material (i.e., low porosity). The attributes outlined above can allow the electrodes to be fabricated with a higher energy density, higher capacity per unit area of electrode (mAh/cm2), and greater thickness than comparable electrodes while still providing high utilization of the active material in the battery during use. Accordingly, the electrodes can be used to produce batteries with high energy densities, high power, or both compared to batteries using electrodes of conventional design with relatively highly tortuous pores.

摘要： The present invention generally relates to batteries or other electrochemical devices, and systems and materials for use in these, including novel electrode materials and designs. In some embodiments, the present invention relates to small-scale batteries or microbatteries. For example, in one aspect of the invention, a battery may have a volume of no more than about 5 mm3, while having an energy density of at least about 400 W h/l. In some cases, the battery may include a electrode comprising a porous electroactive compound. In some embodiments, the pores of the porous electrode may be at least partially filled with a liquid such as a liquid electrolyte. The electrode may be able to withstand repeated charging and discharging. In some cases, the electrode may have a plurality of protrusions and/or a wall (which may surround the protrusions, if present); however, in other cases, there may be no protrusions or walls. The electrode may be formed from a unitary material. In certain embodiments, a nonporous electrolyte may be disposed onto the electrode. Such an electrolyte may allow ionic transport (e.g., of lithium ions) while preventing dendritic formation due to the lack of pores. In certain embodiments the porous electrode has a surface that is denser than its interior. Other aspects of the invention are directed to techniques of making such electrodes or batteries, techniques of forming electrical connections to and packaging such batteries, techniques of using such electrodes or batteries, or the like.
