    摘要： An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode comprises a first lithium ion intercalating carbon component and a second lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, and the second lithium ion intercalating component can include graphite or soft carbon. A ratio of the hard carbon to the graphite or of the hard carbon to the soft carbon can be between 1:19 to 19:1. The anode may comprise a first lithium ion intercalating carbon component, a second lithium ion intercalating carbon component and a third lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, the second lithium ion intercalating carbon component can include soft carbon, and the third lithium ion intercalating carbon component can include graphite.

    摘要： In one aspect, an embodiment of this invention comprises an energy storage device balancing apparatus. The energy storage device balancing apparatus comprises a balancing circuit and an alarm circuit. Both the balancing circuit and the alarm circuit are coupled to the energy storage device. The balancing circuit is configured to monitor a voltage of the energy storage cell and dissipate energy from the energy storage cell if the voltage is at or above a first reference voltage. The alarm circuit is configured to generate an alarm when the voltage of the energy storage cell is at or above a second reference voltage and dissipate energy from the energy storage cell when the voltage is at or above the second reference voltage.

    摘要： A method of fibrillizing a fibrillizable binder component of an electrode film can include providing a negatively charged fibrillizable binder component, and applying an electric field upon the negatively charged binder component to fibrillize the negatively charged fibrillizable binder component. A system for fibrillizing a binder component of an electrode film can include a mixing container made of a material having an affinity to donate electron(s) to the binder component, and an actuator configured to apply a force upon the mixing container so as to contact the mixing container with the binder component and to move the mixing container and the binder component relative to each other within a speed and range of motion sufficient to create an electrostatic force on the binder component and fibrillize the binder component.
