Abstract: Electrolytes, lithium ion cells and corresponding methods are provided, for extending the cycle life of fast charging lithium ion batteries. The electrolytes are based on fluoroethylene carbonate (FEC) and/or vinylene carbonate (VC) as the cyclic carbonate component, and possibly on ethyl acetate (EA) and/or ethyl methyl carbonate (EMC) as the linear component. Proposed electrolytes extend the cycle life by factors of two or more, as indicated by several complementary measurements.

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: The present invention discloses systems and methods for adaptive fast-charging for mobile devices and devices having sporadic power-source connection. Methods include the steps of: firstly determining whether a supercapacitor of a device is charged; upon detecting the supercapacitor is charged, secondly determining whether a battery of the device is charged; and upon detecting the battery is not charged, firstly charging the battery from the supercapacitor. Preferably, the step of firstly determining includes whether the supercapacitor is partially charged, and the step of secondly determining includes whether the battery is partially charged. Preferably, the step of firstly charging is adaptively regulated to perform a task selected from the group consisting of: preserving a lifetime of the battery by controlling a current to the battery, and discharging the supercapacitor in order to charge the battery. Preferably, the discharging enables the supercapacitor to be subsequently recharged.

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. Transparent parts of the pouch may be used for direct sensing of cell elements. Removable covers may be used to protect battery components from illumination damage. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. External sensors may be used to derive data from the indicators, and bi-directional electromagnetic (e.g., optical) communication may be established through the transparent pouch, to enhance monitoring and spare physical electrical connections. For example, the transparent pouch may be used to monitor and enhance battery safety and/or to modify operational parameters non-destructively, during operation of 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.
