Another interesting observation found during the inspection of the second battery to show an issue during observation (Test #7) was the damage found on specific internal pack connectors and cabling. Recalling the images from the Hurricane Sandy Fisker vehicles (Figure 26), similar degradation can be observed on cabling and connectors for this vehicle. This suggests that in addition to acting as a standardized battery abuse test, immersion and post-immersion observation may also be able to replicate certain conditions found in actual vehicle incidents. Figure 26. Connector and wiring damage observed for battery Test #7 While the other batteries tested during these efforts did not show any issues during any of the observation periods, observed issues with two out of seven batteries highlight an area for extended research. Additionally, the shorter durations used for the tests that did show a possible issue with shorter-term immersion in both brackish and seawater. As previously mentioned, this work was exploratory in nature, so these results are merely highlighting and validating the importance of a larger study relative to immersion time and possible probability/severity of incidents. Moreover, these pack sensitivities must be compared to reasonable immersion times from real-world incidents to avoid developing too aggressive of an immersion test, unless the aim is to attempt to identify unknow failure modes similar to the observed cabling and connector degradation. Building on this point further, it is possible that not only the battery cells, but also the entire pack can benefit from immersion testing, so one must keep in mind the goals of a particular experiment and not omit the value of system-level testing to identify possible issues at the interfaces or supporting equipment of a particular battery pack. Clearly from these observed incidents a post-immersion observation period following an immersion test is recommended to better assess the performance of a given battery under these relatively rare circumstances. 3.4 Observations During Incineration In addition to the data and observations taken during and post immersion, the test assets used in this effort were also incinerated following long-term immersion (24+ hours). As with the immersion images and videos, this project sub-component was again done to facilitate the creation of background information and examples of a battery fire in a controlled fashion. To help exemplify this valuable data, Figure 27 shows a time-lapse of the battery incineration for one of the PHEV batteries tested during these efforts. As can be seen in the sequence below, the time-lapse images are useful to understand the progression of the fire from initialization to rather large flames emanating from the pack. It also is useful to provide some basic information related 25PDF Image | Li-Ion Battery Pack Immersion Exploratory Investigation

Product and Development Focus for Salgenx
Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our flow battery manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@salgenx.com | RSS | AMP |
