Methods of manufacturing an electrochemical device, are taught. The methods may be of particular use in the manufacture of thin-film, lightweight, flexible or conformable, electrochemical devices such as batteries, and arrays of such devices. The methods may provide many advantages including stunting fractures in a first electrochemical layer from propagating in a second electrochemical layer.

In accordance with the present invention, deposition of LiCoOlayers in a pulsed-dc physical vapor deposition process is presented. Such a deposition can provide a low-temperature, high deposition rate deposition of a crystalline layer of LiCoOwith a desired () or () orientation. Some embodiments of the deposition addresses the need for high rate deposition of LiCoOfilms, which can be utilized as the cathode layer in a solid state rechargeable Li battery. Embodiments of the process according to the present invention can eliminate the high temperature (>700 C. ) anneal step that is conventionally needed to crystallize the LiCoOlayer. Some embodiments of the process can improve a battery utilizing the LiCoOlayer by utilizing a rapid thermal anneal process with short ramp rates.

The present invention relates to apparatus, compositions and methods of fabricating high performance thin-film batteries on metallic substrates, polymeric substrates, or doped or undoped silicon substrates by fabricating an appropriate barrier layer composed, for example, of barrier sublayers between the substrate and the battery part of the present invention thereby separating these two parts chemically during the entire battery fabrication process as well as during any operation and storage of the electrochemical apparatus during its entire lifetime. In a preferred embodiment of the present invention thin-film batteries fabricated onto a thin, flexible stainless steel foil substrate using an appropriate barrier layer that is composed of barrier sublayers have uncompromised electrochemical performance compared to thin-film batteries fabricated onto ceramic substrates when using a 700 C. post-deposition anneal process for a LiCoOpositive cathode.

A method of forming a lithium orthophosphate sputter target or tile and resulting target material is presented. The target is fabricated from a pure lithium orthophosphate powder refined to a fine powder grain size. After steps of consolidation into a ceramic body, packaging and degassing, the ceramic body is densified to high density, and transformed into a stable single phase of pure lithium orthophosphate under sealed atmosphere. The lithium orthophosphate target is comprised of a single phase, and can preferably have a phase purity greater than 95% and a density of greater than 95%.

The invention relates to a solid-state lithium-ion thin-film electrolyte that, compared to the current state-of-the-art thin-film electrolyte, Lipon, exhibits an equal or larger electrochemical stability window (0-5. 5 V vs. Li/Li), an equal or smaller electronic conductivity (10S/cm at 25 C. ), the same ideal transference number for Li ions (t=1. 000), and a 10× higher Li ion conductivity at −40 C. Latter provides thin-film batteries (TFBs) with at least a 5× higher power performance at −40 C. over the current state-of-the-art Lipon TFBs.

Described herein is, for example, a battery or capacitor over voltage (overcharge) and under-voltage protection circuit, that, for example, is adapted to not draw current from the battery or capacitor to be charged unless charge energy is detected and to not charge an energy storage device when an over-charge condition is sensed. The protection circuit may, for example, not be turned on unless an over voltage condition is present. Incoming energy to the system can be shunted to ground via a shunt load of various types including resistive loads and active components such as a zener diode. In some embodiments, no switching of the inbound power is required. Within limits, no regulation of inbound power is needed. When inbound power is sufficient to charge the battery or capacitor, regulation can occur via the applied shunt regulator if overcharge voltage conditions exist. Either type of charge source, voltage or current, can be used to provide charge energy.
