BioLargo announces results of third-party evalution on Cellinity battery tech

BioLargo (BLGO) announced that a third-party evaluation has confirmed key advantages for its Cellinity battery technology’s use in grid-scale battery energy storage applications. The evaluation was conducted by U.S. BESS Corporation. U.S. BESS senior technical staff performed an examination of Cellinity’s design and assembly protocols, inspection of testing infrastructure, review of data from test results, and an assessment of methodologies used for performance characterization, concluding that the following performance characteristics exclusive of any auxiliary systems are supported by their observations and are reasonably representative of the current Cellinity cell’s demonstrated behavior: Open circuit voltage: greater than 4.2 V; Operating temperature range: from 120 degrees C to 250 degrees C; Energy density: greater than 500 Wh/kg; Power density: greater than 500 mW/cm3; Charge capacity: Cell can be charged to 100% of theoretical capacity; Charge/discharge efficiency: ~100%; Energy efficiency: 95% at 230 degrees C; 87% at 120 degrees C; Self-discharge: No measurable self-discharge observed over test durations; Thermal cycling durability: Performance unaffected after repeated cycling. U.S. BESS Corp further concluded that it is reasonable to claim that the cell would not experience any thermal runaway, materials of construction are commonly available and can be domestically sourced, the cell does not contain any rare earth elements, and cell components are fully recyclable.
