Patent number: 10164242Abstract: 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.Type: GrantFiled: May 19, 2015Date of Patent: December 25, 2018Assignees: Massachusetts Institute of Technology, The Regents of the University of Michigan, The Regents of the University of CaliforniaInventors: Yet-Ming Chiang, Chang-Jun Bae, John William Halloran, Qiang Fu, Antoni P. Tomsia, Can K. Erdonmez

Patent number: 8999571Abstract: 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 an 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 formed from a unitary material. 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.Type: GrantFiled: February 29, 2012Date of Patent: April 7, 2015Assignee: Massachusetts Institute of TechnologyInventors: Yet-Ming Chiang, Ryan C. Wartena, Timothy E. Chin, Can K. Erdonmez, Wei Lai
