Structural Dual-Ion Polymer Batteries for Operation at Low Temperatures
Abstract
Lithium-ion batteries have undergone 30 years of development and dominated the secondary battery market in portable devices. However, in harsher and more complex applications, such as electric vehicles, aerospace, subsea, and power grid operations, lithium-ion batteries still have many insufficiencies nowadays. Two of the most crucial shortcomings are weak mechanical strength and the inability to function at low temperatures. In this work, we focused on these two problems and tried to find a solution. Mechanical strength is delivered with carbon fiber weave current collectors, and we compared the electrochemical performance of carbon fiber current collectors and traditional metal foil meal collectors. Low-temperature operability is realized by a new design of cell configuration, including a dual ion configurated all-organic battery with a specially prepared low-temperature electrolyte. Combining these optimizations and techniques, we are able to fabricate lithium with multifunctionality.
