摘要:
A battery with anti-corrosion protection is provided. The battery can include an electrolyte and a current collector. The electrolyte may be formed from one or more reactive salts capable of corroding the current collector. As such, the current collector may be interposed between a first anti-corrosion layer and a second anti-corrosion layer. The first anti-corrosion layer and/or the second anti-corrosion layer can be configured to prevent the current collector from being corroded by the reactive salts included in the electrolyte by preventing contact between the current collector and the electrolyte. Related methods for corrosion prevention are also provided.

An apparatus and method of keeping an energy storage cell at or above a target temperature, includes receiving at a processing circuit, an analog voltage that is proportional to a temperature of the energy storage cell, converting, at the processing circuit, the analog voltage to a pulse-width-modulated signal having a duty cycle that is proportional to the analog voltage, and driving a switch, with the pulse-width-modulated signal, between conductive and non- conductive states to modulate a voltage passing across (or a current flowing through) a heating element in series with the switch, the heating element being in thermal communication with the energy storage cell, wherein the duty cycle of the pulse-width-modulated signal is adjusted to maintain the temperature of the energy storage cell at or above the target temperature.

A portable electrical energy storage device is provided with a frame (100) that includes a plurality of receptacles (102) for receiving a portion of a portable electrical energy storage cell (200). A cap (910) is provided over the plurality of receptacles (102) and the portion of the portable electrical energy storage cells received in the frame (100). In some embodiments, a passageway (112) extends between adjacent receptacles (102). Disposed within the passageway (112) is a plug which exhibits more resistance to thermal energy migration than other portions of the frame that define the adjacent receptacles.

Provided is an all solid-state lithium battery including solid battery materials and whose ohmic resistance is modulated according to temperature. The all solid-state lithium battery can include a solid electrolyte; at least two terminals for operating the battery at one level of internal resistance (R1) over a temperature range of the battery between a first temperature (T1) and a second temperature (T2); at least one high resistance terminal for operating the battery at a second level of internal resistance (R2) outside of either T1 or T2; and a switch that activates R2 when the temperature of the battery is outside of either T1 or T2. The battery can be configured to include at least one resistor sheet embedded within a cell of the battery and electrically connected to the at least one high resistance terminal.
