    Abstract: Methods and systems are provided for estimating and extending the expected cell cycling lifetime for produced lithium ion cells. Methods comprise monitoring charging and/or discharging peak(s) during formation cycles of the cells, which are defined with respect to dQ/dV measurements during the formation cycles, and ending the formation process once the charging and/or discharging peaks disappear, optionally deriving the expected cell cycling lifetime by comparing the monitored peaks to specified thresholds that are correlated to the lifetime. The methods may be implemented by controller(s) at the battery, device and/or factory levels, which may be operated in combination. Formation processes and/or cell operation schemes may be adjusted accordingly, to avoid excessive dQ/dV rates and increase thereby the cell cycling lifetime.

    Abstract: Lithium ion batteries and cells, as well as operating and testing methods are provided, which utilize a transparent pouch to monitor the battery in operational condition and/or in operation. Covers may be used to prevent illumination of battery components when testing is not required, and the covers may be removed or have modifiable transparency configured to enable visual monitoring. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. For example, the transparent pouch may be used to monitor battery safety, e.g., by enabling to monitor lithium metallization on an anode (directly or via indicators), monitor battery lifetime and other operational parameters, without having to damage the battery.

    Abstract: Methods, systems and battery modules are provided, which increase the cycling lifetime of fast charging lithium ion batteries. During the formation process, the charging currents are adjusted to optimize the cell formation, possibly according to the characteristics of the formation process itself, and discharge extents are partial and optimized as well, as is the overall structure of the formation process. During operation, voltage ranges are initially set to be narrow, and are broadened upon battery deterioration to maximize the overall lifetime. Current adjustments are applied in operation as well, with respect to the deteriorating capacity of the battery. Various formation and operation strategies are disclosed, as basis for specific optimizations.
