Abstract: The disclosed embodiments relate to the manufacture of a precursor co-precipitate material for a cathode active material composition. During manufacture of the precursor co-precipitate material, an aqueous solution containing at least one of a manganese sulfate and a cobalt sulfate is formed. Next, a NH4OH solution is added to the aqueous solution to form a particulate solution comprising irregular secondary particles of the precursor co-precipitate material. A constant pH in the range of 10-12 is also maintained in the particulate solution by adding a basic solution to the particulate solution.

Abstract: Methods and systems for detecting and compensating for expansion of rechargeable batteries over time. An expansion detector may be coupled to or positioned proximate a rechargeable battery to monitor for expansion thereof. After expansion exceeding a selected threshold is detected, the expansion detector may report the expansion to an associated processing unit. The processing unit may undertake to arrest further rechargeable battery expansion by modifying or changing one or more characteristics of charging and/or discharging circuitry coupled to the rechargeable battery. For example, the processing unit may charge the rechargeable battery at a lower rate or with reduced voltage after detecting expansion.
Abstract translation: 随着时间的推移,可充电电池的扩展检测和补偿的方法和系统。 扩展检测器可以耦合到或靠近可再充电电池定位以监测其扩展。 在扩展超过所选择的阈值之后,扩展检测器可以将扩展报告给相关的处理单元。 处理单元可以通过修改或改变耦合到可再充电电池的充电和/或放电电路的一个或多个特性来进一步阻止进一步的充电电池膨胀。 例如,处理单元可以在检测到扩展后以较低的速率或降低的电压对可充电电池充电。

Abstract: Methods of making such compounds, powders, and cathode active materials are described. The powders are formed of particles with specific properties: a particle size distribution with a D50 ranging from 10 μm to 20 μm, a D10 less than 8 μm, and a D99 of the particles ranges from 25 μm to 35 μm. The final compound is represented by the Formula Liα(Co1-x-y-zMnxMezAly)Oδ, wherein 0.95

Abstract: An anode active material comprises a silicon-carbon secondary particle comprising a composite having an exterior conformal carbon coating and formed of type I primary particles. Each type I primary particle comprises a core particle of interconnected silicon, the interconnected silicon formed of nano-sized silicon particles each connected to at least one other particle, inner pores internal to the core particle and defined by the interconnected silicon, an internal carbon coating on internal wall surfaces of the inner pores and a conformal carbon coating on the core particle.
