摘要： Combinations of materials are described in which high energy density active materials for negative electrodes of lithium ion batteries. In general, metal alloy/intermetallic compositions can provide the high energy density. These materials can have moderate volume changes upon cycling in a lithium ion battery. The volume changes can be accommodated with less degradation upon cycling through the combination with highly porous electrically conductive materials, such as highly porous carbon and/or foamed current collectors. Whether or not combined with a highly porous electrically conductive material, metal alloy/intermetallic compositions with an average particle size of no more than a micron can be advantageously used in the negative electrodes to improve cycling properties.

摘要： High capacity silicon based anode active materials are described for lithium ion batteries. These materials are shown to be effective in combination with high capacity lithium rich cathode active materials. Supplemental lithium is shown to improve the cycling performance and reduce irreversible capacity loss for at least certain silicon based active materials. In particular silicon based active materials can be formed in composites with electrically conductive coatings, such as pyrolytic carbon coatings or metal coatings, and composites can also be formed with other electrically conductive carbon components, such as carbon nanofibers and carbon nanoparticles. Additional alloys with silicon are explored.

摘要： Supplemental lithium can be used to stabilize lithium ion batteries with lithium rich metal oxides as the positive electrode active material. Dramatic improvements in the specific capacity at long cycling have been obtained. The supplemental lithium can be provided with the negative electrode, or alternatively as a sacrificial material that is subsequently driven into the negative electrode active material. The supplemental lithium can be provided to the negative electrode active material prior to assembly of the battery using electrochemical deposition. The positive electrode active materials can comprise a layered-layered structure comprising manganese as well as nickel and/or cobalt.

摘要： Lithium ion batteries can be activated and then cycled to exploit a moderate fraction of the discharge cycling capacity such that the discharge capacity and average discharge voltage stay within initial values for thousands of cycles. The superior cycling performance has been achieved at relatively high discharge rates and for practical battery formats. Lithium ion battery performance can also be achieved with superior cycling performance with partially activated batteries such that good discharge capacities can be exploited for many thousands of cycles before the discharge capacity and average discharge voltage drops more than 20% from initial values. The positive electrode active material can be a lithium rich metal oxide. The activation of the battery can comprise phase changes of the active materials. As described herein, the phase changes can be manipulated to exploit a reasonable fraction of the available high capacity of the material while providing outstanding cycling stability.

摘要： Batteries with high energy and high capacity are described that have a long cycle life upon cycling at a moderate discharge rate. Specifically, the batteries may have a room temperature fifth cycle discharge specific energy of at least about 175 Wh/kg discharged at a C/3 discharge rate from 4.2V to 2.5V. Additionally, the batteries can maintain at least about 70% discharge capacity at 1000 cycles relative to the fifth cycle, with the battery being discharged from 4.2V to 2.5V at a C/2 rate from the fifth cycle through the 1000th cycle. In some embodiment, the positive electrode of the battery comprises a lithium intercalation composition with optional metal fluoride coating. Stabilizing additive maybe added to the electrolyte of the battery to further improve the battery performance. The batteries are particularly suitable for use in electric vehicles.
