ADA’s NMC (Nickel Manganese Cobalt oxide cathodes) technology, implemented in small Unmanned Aerial Systems (sUAS), showcases remarkable improvements over Commercial Off-The-Shelf (COTS) cells: - Total Pack Capacity: 76% increase, with ADA packs providing 10.5 Ah compared to 6 Ah from standard COTS cells. - Total Pack Energy: 70% more energy (451.8Wh vs. 266.4Wh). - Run Time: 76% longer run times, crucial for extended missions, with a 25A draw providing 25.3 minutes of operation versus 14.4 minutes with standard cells.
What is so special and valuable about Safe Li-Ion™ zero volt cells and batteries: - Safe to store for months at 0 volt with near 100% recovery. - Safe to transport and battery assembly at 0 volt. - Safe in operations at full charge with superior tolerance in overcharge and overdischarge. - Broad operating temperature range (-40°C to +60°C). - High charge/discharge rate (15C-30C). - Domestically manufactured.

ADA’s Safe Li-Ion™ Cell technology offers high rate capability and utilizes a high safety chemistry that enables 0V storage capability. These cells are engineered to deliver a long cycle life at a 15C rate and capable to operate in extreme low-temperature environments. Safe Li-Ion™ Cell Level Testing (demonstrated in 3.5Ah pouch cell format): - External Short Circuit: Cells withstand short circuits as per S9310 standards, showing a maximum temperature of 62°C, significantly below traditional cell thresholds. - Overcharge/Over-discharge: ADA cells maintain performance even when overcharged or over-discharged beyond standard voltage limits, delivering extra capacity without irreversible loss. - High-Temperature Test: ADA cells can sustain higher temperatures (up to 240°C) without triggering thermal events, unlike traditional cells that fail at around 150°C.
