摘要： High specific capacity lithium rich lithium metal oxide materials are coated with inorganic compositions, such as metal fluorides, to improve the performance of the materials as a positive electrode active material. The resulting coated material can exhibit an increased specific capacity, and the material can also exhibit improved cycling. The materials can be formed while maintaining a desired relatively high average voltage such that the materials are suitable for the formation of commercial batteries. Suitable processes are described for the synthesis of the desired coated compositions that can be adapted for commercial production.

摘要： Improved cycling of high voltage lithium ion batteries is accomplished through the use of a formation step that seems to form a more stable structure for subsequent cycling and through the improved management of the charge-discharge cycling. In particular, the formation charge for the battery can be performed at a lower voltage prior to full activation of the battery through a charge to the specified operational voltage of the battery. With respect to management of the charging and discharging of the battery, it has been discovered that for the lithium rich high voltage compositions of interest that a deeper discharge can preserve the cycling capacity at a greater number of cycles. Battery management can be designed to exploit the improved cycling capacity obtained with deeper discharges of the battery.
