摘要： A method of charging a battery is provided that alters the amount of energy stored within the battery based upon a temperature profile across time. Battery materials and components, like liquid electrolyte or electrodes for instance, can be damaged when a rechargeable cell is exposed to elevated temperatures for extended amounts of time, thereby reducing the overall amount of energy that may be stored within the cell. This method monitors stored energy capacity and temperature. When a fully-charged cell is held at a temperature that exceeds a predetermined temperature threshold for an extended amount of time, the method discharges the cell, thereby reducing the amount of energy stored within the cell. For example, when a single, lithium-ion cell is maintained at 4.2 V for over 10 hours, the method will discharge the cell by roughly 1% or 50 mV. The discharge may be either automatic, or at the prompt of a user.

摘要： A battery pack with reduced magnetic field emissions includes a plurality of cells (1301,1302) coupled electrically together by a first electrical conductor (1307) and a second electrical conductor (1308). The first electrical conductor (1307) couples positive terminals (1305,1306) to a terminal block (1311), while the second electrical conductor (1308) couples the negative terminals (1303,1304) to the terminal block (1311). Each cell (1301,1302) contains an asymmetrical internal electrode construction (1313,1314) having electrical tabs (502,503) coupled to a cathode and anode. The cells (1301,1302) can be arranged with their corresponding asymmetrical internal electrode constructions (1313,1314) oriented in different directions to reduce magnetic field emissions. The first electrical conductor (1307) and second electrical conductor (1308) can be routed such that magnetic fields generated by discharge currents tend to reduce other magnetic fields produced by other components within the battery pack.

摘要： A battery pack having at least one electrochemical cell and a temperature dependent boost circuit is provided. Since the cell voltage is diminished at low temperatures, and as portable electronic devices typically have a minimum operational voltage limit, the boost circuit is actuated at low temperatures to step up the voltage from the cell to the electronic device. In one embodiment, the boost circuit is coupled serially between the cell and the output terminals of the battery pack. In parallel with the boost circuit is a boost bypass circuit. A controller senses the temperature of the battery pack from a temperature sensor, like a thermistor. When the temperature falls below a predetermined minimum temperature threshold, the controller actuates the boost circuit, thereby increasing the output voltage of the pack. Concurrently with the actuation of the boost circuit, the controller causes the boost bypass circuit to enter a high impedance state.

摘要： A lithium-ion battery having at least an anode that includes phenol formaldehyde in a range of 0.1% to 10% by weight as a binder material. The phenol formaldehyde, or a mixture of phenol formaldehyde with polyvinylidene fluoride (PVDF), is used as a binding material in a Li-ion battery negative electrode to decrease the exothermic reaction of the battery during charging and discharging, which accordingly lessens the risk of thermal runaway and rupture of the battery.
