Dimensional constraints for three-dimensional batteries

A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%. ...

Replenished negative electrodes for secondary batteries

A method is provided for activating a secondary battery having a negative electrode, a positive electrode, and a microporous separator between the negative and positive electrodes permeated with carrier-ion containing electrolyte, the negative electrode having anodically active silicon or an alloy thereof. The method includes transferring carrier ions from the positive electrode to the negative electrode to at least partially charge the secondary battery, and transferring carrier ions from an auxiliary electrode to the positive electrode, to provide the secondary battery with a positive electrode end of discharge voltage vpos,eod and a negative electrode end of discharge voltage vneg,eod when the cell is at a predefined vcell,eod value, the value of vpos,eod corresponding to a voltage at which the state of charge of the positive electrode is at least 95% of its coulombic capacity and vneg,eod is at least 0.4 v (vs li) but less than 0.9 v (vs li).. ...

Longitudinal constraints for energy storage devices

A energy storage device for cycling between a charged state and a discharged state, the energy storage device including an enclosure, an electrode assembly and a non-aqueous liquid electrolyte within the enclosure, and a constraint that maintains a pressure on the electrode assembly as the energy storage device is cycled between the charged and the discharged states.. . ... Enovix Corporation

Microstructured electrode structures

A structure for use in an energy storage device, the structure comprising a backbone system extending generally perpendicularly from a reference plane, and a population of microstructured anodically active material layers supported by the lateral surfaces of the backbones, each of the microstructured anodically active material layers having a void volume fraction of at least 0.1 and a thickness of at least 1 micrometer.. . ... Enovix Corporation

Three-dimensional batteries and methods of manufacturing the same

Various methods and apparatus relating to three-dimensional battery structures and methods of manufacturing them are disclosed and claimed. In certain embodiments, a three-dimensional battery comprises a battery enclosure, and a first structural layer within the battery enclosure, where the first structural layer has a first surface, and a first plurality of conductive protrusions extend from the first surface. ... Enovix Corporation

Electrode structures for three-dimensional batteries

An electrode structure for use in an energy storage device comprising a population of electrodes, a population of counter-electrodes and a microporous separator separating members of the electrode population from members of the counter-electrode population. Each member of the electrode population comprises an electrode active material layer and an electrode current conductor layer, and each member of the electrode population has a bottom, a top, a length le, a width we and a height he, wherein the ratio of le to each of we and he is at least 5:1, the ratio of he to we is between 0.4:1 and 1000:1, and the electrode current collector layer of each member of the electrode population has a length lc that is measured in the same direction as and is at least 50% of length le.. ...
