20090035662 | NEGATIVE-LIMITED LITHIUM-ION BATTERY - A rechargeable lithium-ion battery includes a positive electrode that includes a first current collector and a first active material. The battery also includes an electrolyte and a negative electrode that includes a second current collector and a second active material, where the second active material includes a lithium titanate material. The positive electrode has a first capacity and the negative electrode has a second capacity, the second capacity being less than the first capacity such that the rechargeable lithium-ion battery is negative-limited. | 02-05-2009 |
20090274849 | FORMATION PROCESS FOR LITHIUM-ION BATTERIES - A method for producing a battery includes providing a battery having a positive electrode, a negative electrode, and an electrolyte that includes a solvent and a salt. The capacity of the negative electrode is less than that of the positive electrode and the negative electrode includes an active material having an average potential versus a lithium reference electrode of greater than approximately 0.2 volts. The method also includes applying an initial charge to the battery at a voltage that is greater than a fully charged voltage of the battery for a sufficient amount of time to cause at least a portion of the solvent to undergo a reduction reaction. The step of applying an initial charge to the battery acts to increase the irreversible capacity loss of the battery during the initial charge and provides the battery with enhanced tolerance to deep discharge conditions. | 11-05-2009 |
20100279155 | LITHIUM-ION BATTERY WITH ELECTROLYTE ADDITIVE - A rechargeable lithium-ion battery includes a positive electrode and a negative electrode that includes a lithium titanate active material. A separator is provided between the positive electrode and the negative electrode. The battery also includes an electrolyte and an electrolyte additive comprising at least one boroxine ring. | 11-04-2010 |
20110281148 | NEGATIVE-LIMITED LITHIUM-ION BATTERY - A rechargeable lithium-ion battery includes a positive electrode having a first capacity and a negative electrode having a second capacity that is less than the first capacity such that the battery has a negative-limited design. The negative electrode includes a lithium titanate active material. A liquid electrolyte that includes a lithium salt dissolved in at least one non-aqueous solvent a porous polymeric separator are located between the positive electrode and negative electrode. The separator is configured to allow lithium ions to flow through the separator. | 11-17-2011 |
20130029207 | BATTERY WITH AUXILIARY ELECTRODE - A lithium-ion battery includes a case, an electrolyte, a positive electrode, a negative electrode, and an auxiliary electrode. The positive electrode includes a current collector and an active material. The negative electrode includes a current collector and an active material. The auxiliary electrode includes an active material. The electrolyte, positive electrode, and negative electrode are disposed within the case. The auxiliary electrode is configured to selectively couple to the negative electrode to irreversibly absorb lithium from the negative electrode. | 01-31-2013 |
20130164584 | NEGATIVE-LIMITED LITHIUM-ION BATTERY - A rechargeable lithium-ion battery includes a housing including a titanium or a titanium alloy, a positive electrode having a first capacity and at least one positive active material selected from the group consisting of LiCoO | 06-27-2013 |
