Abstract
Excellatron proposes to optimize an all solid-state secondary battery for safety. The all solid-state battery combines the high energy density of Li-ion technology with the power density, cyclability, and proven safety of thin film all solid-state battery technology developed at Oak Ridge National Labs. Despite the use of Li as the anode to maintain the highest possible energy density, the proposed all solid state battery allows for a cell that will be ultra safe even in the most extreme and abusive environments owing to the elimination of highly flammable liquid electrolyte used in current Li-ion technology. Even when ruptured at high or low temperatures or in underwater environments or short circuited or fast charged to overvoltage conditions the cell will remain safe. No overvoltage or deep discharge “safety” protection circuit will be necessary, or any provision for venting of gasses to prevent explosion. In fact the solid state prismatic design will be extremely resilient to puncture or venting even when crushed, and will provide dramatic improvements in durability and reliability under rough handling over existing technologies. The battery will extend the military temperature range of –40oC to 85oC to an increased upper limit of 150°C.
