the event. Once destroyed, the batteries were removed from the container to make room for additional test batteries from the immersion. Examples of the process steps are shown in Figure 16. Figure 16. Overview of final battery destruction process 2.4 Overview of Testing Assets and Conditions The seven batteries used for testing were provided by NHTSA and represented a mix of BEV and PHEV battery packs from recent testing assets, described in Table 1. While not all batteries were from the most recent model year, the sampling included a mix of modern batteries from a range of manufacturers. This mix of manufacturers was helpful to contribute to the overall exploratory nature of this testing by allowing for a range of chemistries and design topologies to be assessed. The core of the testing, Batteries 1–5, was done using a 3.5 percent (35 PPT) salinity immersion to emulate seawater and roughly match the conditions of other immersion tests discussed in the introduction. Two additional tests took place in brackish water, which has a lower salinity level compared to sea water. As mentioned, the salinity level at which an immersion test takes place may provide a different immersion and post-immersion response and is very much a topic for further study, as brackish water is broadly defined as anything less than about 35 PPT. For this testing, the two batteries highlighted in blue were tested in a very low 0.1 percent (1 PPT) salinity immersion. This was done in an attempt to roughly match the salinity levels observed and thus conductance of 1,950-2,000 uS1 for certain types of battery coolant in previous research efforts undertaken by NHTSA (Smith, 2012). 1 Microsiemens per centimeter are designated interchangeably as μS/cm or uS/cm, or just uS. 16PDF 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 (Standard Web Page)
