Battery and method for the production thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a thin, flexible battery that is manufactured using printing techniques with functional inks. All layers of the battery, including electrodes, separators, and electrolyte, are formed by printed inks and designed to be water-based but water-insoluble. The construction allows for simple lamination using unpatterned rollers, enabling low-cost, scalable production of batteries that are particularly well-suited for applications needing lightweight, disposable, or flexible power sources.

Use CasesContent extracted from patent full text and abstract with AI.

• Smart packaging (e.g., food, pharmaceuticals, or consumer goods) requiring temporary power for sensors or displays
• Disposable medical devices or test kits
• RFID tags and electronic labels
• Greeting cards and novelty items with embedded electronics
• Single-use sensors or indicators (e.g., temperature or freshness sensors for perishables)
• Thin, flexible wearable electronics
• Lightweight, low-power wireless devices

BenefitsContent extracted from patent full text and abstract with AI.

• Low-cost production due to use of widely available printing technologies and elimination of clean-room or specialized lamination equipment
• Mechanical flexibility enables use on curved or irregular surfaces
• Thinness allows integration into compact or space-constrained products
• Water-based materials are safer and enable easier disposal
• Scalable manufacturing for high-volume, disposable electronics
• Customization of battery shape and size to suit specific applications
• Potential for on-demand or localized manufacturing, reducing logistics and inventory costs

Patent Abstract

A thin battery 300, preferably a printed battery, comprises a first substrate 301 and a second substrate 302. A cathode layer 307 and an anode layer 308 are printed on the first substrate 301 and on the second substrate 302, respectively. The binders in the cathode layer 307 and in the anode layer 308 are preferably water insoluble polymers. A separator layer 310, 311 is printed on at least one of the cathode layer 307 and the anode layer 308. The separator layer 310, 311 comprises interconnected water absorbing powders. An electrolyte layer 320 is printed on the at least one separator layer 310, 311. The electrolyte layer 320 comprises water, at least one salt, water insoluble substantially spherical particles 321 and at least one waxy material 322. The first substrate 301 is secured on the second substrate 302 in such a way that the separator layer 310, 311 and the electrolyte layer 320 are sandwiched between the cathode layer 307 and the anode layer 308.
