Rechargeable battery cells and methods for extreme fast charging are disclosed. For example, such a rechargeable battery cell might be chargeable to at least 70% of usable capacity within 15 minutes. Such a rechargeable battery cell may include an anode having at least one surface with a reversible areal capacity, after formation, up to 8.0 mAh/cm, containing a Si—C composite within a porous structure and including a carbon-based conductive additive, wherein the Si—C composite is at least 30% Si by weight, and the material is at least 85% Si—C composite. The rechargeable battery cell may also include a cathode having at least one surface with a reversible areal capacity, after formation, up to 6 mAh/cm, wherein a ratio of areal capacity of the at least one surface of the anode to the at least one surface of the cathode is between 1.15 to 1.45.

Li-ion cells with extreme fast charging capabilities

Rechargeable battery cells and methods for extreme fast charging are disclosed. For example, such a rechargeable battery cell might be chargeable to at least 70% of usable capacity within 15 minutes. Such a rechargeable battery cell may include an anode having a conductive current collector coated with a composite containing a carbon-based material, a cathode configured as a source of Li ions, an electrolyte capable of carrying Li-ions between the anode and the cathode, and a separator between the anode and the cathode, the separator having a thickness of less than 20 microns. Methods of charging the rechargeable battery cells are also disclosed.

Rechargeable battery cell with ultra thin separator

Rechargeable battery cells and methods for extreme fast charging are disclosed. For example, such a rechargeable battery cell might be chargeable to at least 70% of usable capacity within 15 minutes. Such a rechargeable battery cell may include an anode having at least one surface with a reversible areal capacity, after formation, up to 8.0 mAh/cm, and a cathode having at least one surface with a reversible areal capacity, after formation, up to 6 mAh/cm, wherein a ratio of areal capacity of the at least one surface of the anode to the at least one surface of the cathode is between 1.15 to 1.45. Methods of charging rechargeable battery cells disclosed herein under conditions sufficient to enable charging of at least 70% of usable capacity to the rechargeable battery cell within 15 minutes, are also disclosed.

Rechargeable battery cell with increased areal capacity

A system for the automatic grading of a cut/polished gemstone (SUT) includes an enclosure with a stage for mounting the cut/polished SUT. The enclosure further includes one or more sources of broadband visible (BBV) light, the sources of BBV light being controllable by a programmable controller; an image sensor for capturing a plurality of images of a mounted SUT, and one or more sources of UV light mounted within the enclosure. The controller captures images of the mounted SUT from one or more selected angles relative to the sensor elevation axis and relative to the position of the SUT on the stage rotation axis; an image capturing module is configured for processing the one or more images; and, a light grade calculation module is configured for grading the cut/polished SUT using light indicative parameters from at least a part of the one or more images captured.

System and method for evaluating and determining color in gemstones

Methods of managing a lithium ion battery and of recovering branches and/or cells in the battery are provided, as well as battery management systems (BMS) and batteries implementing the methods. Branches and/or cells may be recovered by slow and deep discharging, followed by slow charging&#x2014;to increase capacity, cycling lifetime and/or enhance safety thereof. BMSs may be configured to diagnose defective branches and/or cells and manage the recovery procedure with respect to changing operational loads the battery and the available internal and external charging sources.
