2 Testing Overview To investigate and collect information surrounding the immersion behavior of several recent Li- ion hybrid-electric and battery-electric vehicle batteries, a series of experimental immersion scenarios and procedures were used to consistently and safely evaluate the batteries relative to their safety performance during and after immersion. As the goal of testing was to gain preliminary insights and suggest further research directions for more detailed examinations of issues related to vehicle battery immersion and any subsequent risks (specifically thermal events) during and following the immersion of the battery vehicle, an overview of the process is provided below to enable a better understanding of the basic steps used across all experiments. The following sections provide additional details and rationale for the equipment and procedures chosen for this exploratory research work. 2.1 Test Facility and Equipment 2.1.1 Precautions and Safety Considerations While not exhaustive, this section covers basic precautions and safety recommendations. When working on or around high-voltage systems, always follow the appropriate safety precautions. Read and follow the recommended service procedures for high-voltage systems and high-voltage parts for the vehicle/system under test. Be sure to wear the appropriate personal protective equipment, which includes Class 0 insulated rubber gloves with leather outer gloves. Always inspect the insulated gloves for defects that might prevent the insulating properties, and do not wear them if they are damaged. 2.1.2 Test Equipment and Setup As discussed in the introduction, the testing in this project aimed at assessing the immersion of batteries during the initial and subsequent immersion as well as behaviors related to initial or long-term reactions following removal of the battery from the immersion conditions. To these ends, the testing equipment use for these experiments needed to provide a safe location for immersion, a means to lower and raise the device-under-test into and out of the immersion, and a means to observe the on-going experiments and monitor for any incidents. An overview of the key equipment is shown in Figure 4. The reader can see the immersion tank, a repurposed dumpster, as well as the lift mechanism to raise and lower the battery into the tank. The lift mechanism was placed on the forks of a fork-lift to provide the starting height from which the battery could be raised or lowered. Care was taken to ensure the lift has sufficient capability for the various batteries examined, as some were over 400kg. The lift could be operated remotely, allowing the battery to be re-lowered quickly and easily should any issue be encountered during observation above the tank. In contrast to a specific observation area, it was decided early on during experimental developments that the battery should be observed directly over the immersion tank, so if an incident was detected, the battery could quickly go back into the immersion, most likely stopping problem. A remote camera fixed to a lift was used as the primary video collection apparatus as it allowed for directly viewing into the immersion tank and during observation, while allowing test operators to stay a safe distance away in case any thermal issues arose during testing. 7PDF 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)
