摘要： Provided are: an anode active material for a lithium ion secondary battery with which high initial efficiency and battery capacity can be maintained and excellent cycling characteristics are achieved; and a method for producing such an active material. The anode active material for a lithium ion secondary battery, the active material comprising a Si compound and a carbonaceous material or a carbonaceous material and graphite, is obtained by a method comprising the steps of: mixing a Si compound, a carbon precursor, and, as appropriate, graphite powder; performing granulation/compaction; pulverizing the mixture to form composite particles; firing the composite particles in an inert gas atmosphere; and subjecting the pulverized and conglobated composite powder or the fired powder to air classification.

摘要： Disclosed are battery management systems with control logic for battery state estimation (BSE), methods for making/using/assembling a battery cell with a reference electrode, and electric drive vehicles equipped with a traction battery pack and BSE capabilities. In an example, a battery cell assembly includes a battery housing with an electrolyte composition stored within the battery housing. The electrolyte composition transports ions between working electrodes. A first working (anode) electrode is attached to the battery housing in electrochemical contact with the electrolyte composition. Likewise, a second working (cathode) electrode is attached to the battery housing in electrochemical contact with the electrolyte composition. A reference electrode is interposed between the first and second working electrodes, placed in electrochemical contact with the electrolyte composition. The reference electrode and one or both working electrodes cooperate to output a half-cell voltage signal that is indicative of a battery state of the battery cell assembly.

摘要： The instant disclosure sets forth multiphase lithium-stuffed garnet electrolytes having secondary phase inclusions, wherein these secondary phase inclusions are material(s) which is/are not a cubic phase lithium-stuffed garnet but which is/are entrapped or enclosed within a lithium-stuffed garnet. When the secondary phase inclusions described herein are included in a lithium-stuffed garnet at 30-0.1 volume %, the inclusions stabilize the multiphase matrix and allow for improved sintering of the lithium-stuffed garnet. The electrolytes described herein, which include lithium-stuffed garnet with secondary phase inclusions, have an improved sinterability and density compared to phase pure cubic lithium-stuffed garnet having the formula Li7La3Zr2O12.

摘要： A battery balancing system for parallel connected batteries for balancing batteries that are at dissimilar voltages. The system has first and second buses, connected by a current limiter. A high bus takes energy from the highest voltage battery or batteries in the system and transfers the energy through the current limiter to the low bus, which in turn delivers energy to the lowest voltage battery or batteries in the system.
