Use of lithium batteries is increasing which is utmost source of off-the-grid electrical system. The performance, efficiency and lifetime of lithium battery are highly dependent on the state of the operating temperature. Thermal runaway occurs in lithium battery during the discharge process when uncontrolled loop is formed between the heat generation and temperature-rise, causing faster release of stored energy, this could lead to fires, and explosions. The present industrial method in thermal management strategies can primarily be divided into two categories; the first one is a more mechanical way of reducing the battery temperature by taking factors like its thermal resistance into consideration and the second method tackles the heat source directly by preventing the battery reaching critical temperatures during operation. Our is most sound and can be easily integrated into existing technology with minimum investment. So, hybrid vehicles can be the best target for this technology. PolyMaterials App, LLC (PolyMaterials) has developed a new technology to manage the temperature rise in batteries, particularly Li batteries using supercapacitor, to avoid thermal runaway in the energy storage system. Thermal run away can be avoided by using the supercapacitor with lithium battery in the energy storage system. We are applying the machine learning based algorithm in the control system which will further control the charge/discharge cycles to avoid reaching the critical thermal runaway temperature. PolyMaterials is developing technology which will reduce the risk for thermal runaway in battery. The proposed integrated technology is the first of its kind to save thermal runaway and would be implemented in a wide range of DoD and commercial applications such as hybrid vehicles, electronics & peak power grid assistance, drones, emergency power back and many power application devices. The project includes modeling, design, manufacturing, and integration of components into an efficient device energy storage device. Our initial study 5 to 6 V lithium battery with supercapacitor has shown the thermal management of energy storage devices. We will study & integrate a 12 to 110-V and higher circuit connected in parallel with multi cells SCs with funding. After analyzing all the battery thermal management end-use industries, such as aerospace and defense, automotive, servers and data centers and consumer electronics. PolyMaterials App LLC expects to be of interest, primarily to the automotive market, and aerospace and defense. In which there is a constant need for improved thermal management of high-power application devices. The Thermal Management System market was an estimated $1.6 billion in 2019 and is expected to grow at a compound annual growth rate (CAGR) of 28.5% from 2020 to 2027. We anticipate that PolyMaterials App LLC would capture an average of 0.012% of the thermal management market a year, reaching the expected market share of 0.4% in ten years. Furthermore, we expect a sales revenue average of $20,972,117.27 dollars per year within the next ten years. PolyMaterials estimates cumulative sales revenues of $209,721,173 and cumulative licensing revenues of $146,804,821 during the first 10 years of commercialization.
