“…Typically, energy is first stored at low voltage (<1000 V) in a primary energy storage element, such as a capacitor, after which this energy is transferred to the PFN via e.g. a high-voltage transformer [25][26][27][28] or a Marx generator [29,30]. The operating principles of such charging mechanisms is beyond the scope of this paper, though some will appear in the next sections.…”

Streamer discharges generated by nanosecond high-voltage pulses have gained attraction for a variety of reasons, but mainly because they are very efficient for a number of plasma-processing applications. More specifically, researchers have noted that the pulse duration and the rise time of the applied high-voltage pulse have a significant influence on the radical yield of the transient plasmas generated with these pulses; shorter pulses result in higher yields. With the need to study transient plasmas generated by these short pulses comes the need to understand how to generate those pulses and to understand the interaction between the pulse source and the discharge. In this topical review, we will explore the different methods with which to generate nanosecond highvoltage pulses, how the interaction between the pulse source and the discharge may influence the source and the discharge and how to optimize the energy transfer from the pulse source to the discharge.

“…Recently, electrochemical cell manufacturers have produced high power cells with equivalent series impedances (ESRs) less than 1 m . The reduced ESR has considerably increased the application space for which electrochemical energy storage devices can be used, including hybrid and all-electric vehicles [3,4,5], electric-grid energy storage [6,7], electromagnetic launchers [8,9], and high voltage pulsed power sources [10,11,12,13], among others.…”

UT Arlington is researching the impact high pulsed loading has on high power electrochemical energy storage devices. Fundamental effects on aging due to high pulsed loading are being investigated by studying the capacity fade and changes in the cells electrochemical impedance [1]. Experiments have been performed in which a 3Ah LiNixCoyAl1-x-yO2 cell is discharged at rates as high as 83C (250 A) in a 10 kHz pulsed fashion for 140s. A 1C recharge procedure is used between discharge cycles. The experimental results obtained when cycling at elevated rates are compared to results obtained from a second identical cell which is charged using a 1C constant current (CC) - constant voltage (CV) procedure and discharged at a constant 1C rate. This paper describes the experiments performed and shows the impact high pulsed loading has on the aging and capacity fade of a high power lithium-ion battery after fifty cycles have been performed.

“…The increased power density has opened up the application space for which these devices can be used considerably. A few examples include hybrid and all-electric vehicles [2,3,4], electric-grid energy storage [5,6], electromagnetic launchers [7,8], and high voltage pulsed power sources [9,10,11,12].…”

“…Many high voltage pulsed power sources can drive time varying, low impedance loads. Short pulse generation using solid-state opening switch (SOS) generators, Marx generators, and inductive energy storage have all been demonstrated using rechargeable batteries as their prime power source [9,10,11]. In nearly all of the documented systems, the description of the cells that make up the prime power source makes up an extremely small section of the report.…”

Recently manufacturers of electrochemical energy storage devices have produced cells that are more power dense then previously available. The types of cells include lithium-ion batteries (LIBs), electric-double-layer capacitors (EDLCs), and lithium-ion capacitors (LICs) among others. As a result of the higher power density, the ability to use these devices as the prime power source of compact pulsed power systems is increased. A few pulsed power sources have already been developed which draw their prime power from electrochemical energy storage devices, and the number of systems as well as their capabilities will only increase as the energy storage technologies continue to advance. Though manufacturers often list peak pulsed current capability on the cell datasheet, sometimes the value listed can be limited by the hardware used to test the cells and not always the cells themselves. In order to experimentally validate the pulsed current limitations of some of the newest electrochemical cells, a low impedance test stand, capable of extracting high pulsed current from individual cells has been developed. The impedance of the stand, roughly equal to or less than 1 milli-Ohm, is such that in most cases, the impedance of the cell dominates the discharge current. A description of the test stand and the current limitations of many of the cells tested thus far will be presented.
