摘要： Electrode assemblies for use in electrochemical cells are provided. The negative electrode assembly comprises negative electrode active material and an electrolyte chosen specifically for its useful properties in the negative electrode. These properties include reductive stability and ability to accommodate expansion and contraction of the negative electrode active material. Similarly, the positive electrode assembly comprises positive electrode active material and an electrolyte chosen specifically for its useful properties in the positive electrode. These properties include oxidative stability and the ability to prevent dissolution of transition metals used in the positive electrode active material. A third electrolyte can be used as separator between the negative electrode and the positive electrode.

摘要： A polymer that combines high ionic conductivity with the structural properties required for Li electrode stability is useful as a solid phase electrolyte for high energy density, high cycle life batteries that do not suffer from failures due to side reactions and dendrite growth on the Li electrodes, and other potential applications. The polymer electrolyte includes a linear block copolymer having a conductive linear polymer block with a molecular weight of at least 5000 Daltons, a structural linear polymer block with an elastic modulus in excess of 1×107 Pa and an ionic conductivity of at least 1×10−5 Scm−1. The electrolyte is made under dry conditions to achieve the noted characteristics. In another aspect, the electrolyte exhibits a conductivity drop when the temperature of electrolyte increases over a threshold temperature, thereby providing a shutoff mechanism for preventing thermal runaway in lithium battery cells.

摘要： Nanostructured gel polymer electrolytes that have both high ionic conductivity and high mechanical strength are disclosed. The electrolytes have at least two domains—one domain contains an ionically-conductive gel polymer and the other domain contains a rigid polymer that provides structure for the electrolyte. The domains are formed by block copolymers. The first block provides a polymer matrix that may or may not be conductive on by itself, but that can soak up a liquid electrolyte, thereby making a gel. An exemplary nanostructured gel polymer electrolyte has an ionic conductivity of at least 1×10−4 S cm−1 at 25° C.

摘要： A sulfur-based cathode for use in an electrochemical cell is disclosed. An exemplary sulfur-based cathode is coupled with a solid polymer electrolyte instead of a conventional liquid electrolyte. The dry, solid polymer electrolyte acts as a diffusion barrier for the sulfur, thus preventing the sulfur capacity fade that occurs in conventional liquid electrolyte based cell systems. The solid polymer electrolyte further binds the sulfur-containing active particles, preventing sulfur agglomerates from forming, while still allowing lithium ions to be transported between the anode and cathode.
