    摘要: A secondary battery includes an electrode assembly disposed within a constraint. The electrode assembly comprises a population of unit cells comprising an electrode current collector layer, an electrode layer, a separator layer, a counter-electrode layer, and a counter-electrode current collector layer in stacked succession. A subset of the unit cell population includes extended spacer members between the electrode current collector layer and the counter-electrode current collector layer. One of the spacer members is spaced in a transverse direction from the other extended spacer member, at least a portion of the counter-electrode active material of the counter-electrode layer being located between the spacer members such that the portion of the counter-electrode active material and the spacer members lie in a common plane defined by x and z axes, wherein each of the extended spacer members extend a distance SD in the x-axis direction beyond an x-axis edge of the constraint.

    摘要: Provided is a battery in which the internal resistance is further decreased. The present disclosure provides a battery, comprising a positive electrode, a negative electrode, and an electrolyte layer provided between the positive electrode and the negative electrode. The electrolyte layer includes a first solid electrolyte material. The first solid electrolyte material includes Li, M, and X, and does not include sulfur. M is at least one selected from the group consisting of metalloid elements and metal elements other than Li. X is at least one selected from the group consisting of Cl, Br, and I. The negative electrode includes a negative electrode active material and a sulfide solid electrolyte.

    摘要: The invention relates to a metal accumulation inhibiting and performance enhancing isolated or synthesized supplement for use in or in association with rechargeable electrochemical energy storage cells, and a system for delivering the supplement including articles of plastic, articles containing plastic, articles similar to plastic, plastic containers, apparatus, porous electrodes, liquids and electrolytes, in particular, articles, apparatus, electrodes, insolating sheets, liquids and electrolytes associated with rechargeable electrochemical energy storage cells incorporating one or more supplements. An effective amount of the supplement typically exhibits foaming of an electrolyte, providing a visual indicator of activity in attenuating metal deposition on, and thereby reducing metal accumulation on, various surfaces in the rechargeable electrochemical storage cell.
