摘要： The invention provides an electrochemical cell having an electrolyte which comprises a solute, a solvent, and an additive. The additive is a dialkylamide. The dialkylamide lessens the extent of decomposition of the solute, which is a lithium salt. The ionic species of the lithium salt are thereby preserved. The additive also prevents damage to active material by absorbing excess charge energy below the breakdown potential of the active material.

摘要： Disclosed herein is a battery design for bi-cell polymer matrix batteries. Each bi-cell comprises, sequentially, a first counter electrode, a first separator membrane, a centrally located electrode, a second separator membrane, and a second counter electrode. The current collector of each of the counter electrodes is positioned other than medially within the counter electrode. Generally, the current collector of the counter electrode is located within the outer half of the counter electrode. When the current collector is located at the extreme outer edge of the counter electrode, a capping film of polymer matrix material is preferably laminated to the perforated current collector, and, through the perforated current collector, to the counter electrode material itself.

摘要： The subject invention discloses a novel method of providing a binary electrolyte-solvent solution in a solid battery system. A first component of this binary electrolyte solvent system is provided by a material which acts as a plasticizer in the formation of a solid polymeric matrix (separator), composite cathode and/or composite anode, and which also acts as an electrolyte solvent in the completed electrochemical cell. The second component of the binary electrolyte solvent system is an electrolyte solvent, which generally carries the electrolyte salt into the electrolytic cell precursor. The first and second components of the binary electrolyte solvent system mix within the electrolytic cell, dispersing the electrolyte salt throughout the binary electrolyte solvent system. The addition of the electrolyte salt to the electrolytic cell precursor acts to activate the cell precursor, and to form a functional electrolytic cell or battery system.

摘要： The present invention provides an electrochemical cell or battery which has a non-metallic negative electrode (anode). That is, no solid metal, free metal, active material is used in the cell. Rather than the conventional solid lithium metal anode, the active material of the new electrode comprises substituted carbon active material. The substituted carbon is carbonaceous material arranged in a disordered or ordered graphite structure, where atoms of carbon have been substituted in such structure by at least one other element. The invention also provides carbonaceous materials which are non-graphitic and considered amorphous, non-crystalline, highly disordered, which also have substituted therein elements other than carbon. The invention also provides a process for making such substituted carbons and for preparing an anode containing the substituted carbon.

摘要： Non-aqueous solid electrochemical cells with improved performance can be fabricated by employing intercalation based carbon anodes comprising a mixture of carbon particles having different morphologies and selected from platelet-type, microbead-type and/or fiber-type structures. The anodes exhibit good cohesion and adhesion characteristics. When employed in an electrochemical cell, the anode can attain a specific electrode capacity of at least 300 mAh/g. The electrochemical cell has a cycle life of greater than 1000 cycles, and has a first cycle capacity loss of only about 5-15%.
