Advancements in Printed Batteries: A Comprehensive Overview

Printed batteries are revolutionizing the energy storage sector with their potential for low-cost, flexible, and customizable power solutions. Among the various chemistries explored for printed batteries, zinc–manganese stands out due to its affordability, safety, and ease of processing. Since the first commercial printed battery by Power Paper in 1997, the market has seen significant developments with companies like Blue Spark Technologies, Enfucell, Imprint Energy, and Printed Energy leading the charge.

Zinc–Manganese Chemistry: A Foundation for Innovation

Zinc–manganese batteries have been the backbone of many commercial printed battery products, particularly for disposable applications such as medical and cosmetic skin patches. However, these batteries are inherently non-rechargeable, prompting a shift towards developing rechargeable alternatives. While lithium-ion batteries offer high energy density and rechargeability, their manufacturing process demands a moisture-free environment and poses safety risks, making them less ideal for printing applications.

To overcome these limitations, researchers are exploring other chemistries like nickel-metal hydride (NiMH), radical polymer, and zinc–air. These alternatives aim to balance safety, efficiency, and the practicality of printing technologies.

Current Collectors: Bridging Conductivity and Flexibility

The choice of current collector materials is critical in printed batteries. Traditional metallic foils, such as aluminum and copper, offer excellent conductivity but lack the flexibility needed for integrated devices. Alternative technologies involve depositing conductive materials like aluminum thin films onto flexible polymer substrates via vacuum deposition or printing conductive inks. Conductive inks, containing particles of metals such as silver, copper, and aluminum, present a versatile solution. They can be processed at moderate temperatures, ensuring compatibility with flexible substrates like polyethylene terephthalate (PET).

Innovations in Printable Electrodes

Electrodes in printed batteries are typically produced by casting viscous slurries containing active materials, conductive additives, and binders onto current collectors. This method has been adapted to various printing techniques, including screen printing, stencil printing, and spray coating. The challenge lies in achieving a balance between electrode thickness for energy capacity and maintaining low internal resistance for efficient power delivery. Innovations in electrode formulation focus on optimizing the slurry's rheological properties to enhance performance and flexibility.

Printable Electrolytes and Separators: Overcoming Challenges

Developing a printable electrolyte/separator for rechargeable batteries remains a significant hurdle. Various approaches are being explored:

1. Acrylic Membrane Separators: These are printed with embedded liquid electrolytes and then cross-linked using chemical or photo-initiators. This method provides mechanical stability and ionic conduction.

2. Polymer Blends: Mixing liquid electrolytes with preformed polymers such as polyethylene oxide (PEO) and poly(vinylidene fluoride) (PVDF) offers flexibility and improved ionic conductivity.

3. Silica-Based Ionogels: Inspired by lead–acid battery technology, this method uses silica particles to provide physical separation and support for the liquid electrolyte.

4. Biological Structures: Printed Energy has innovated using diatom frustules, a biological material, to create printable separators with natural porosity.

5. Co-Planar Battery Geometry: This design eliminates the need for a separator by extending the ionic diffusion path, though it increases internal resistance.

Practical Considerations and Performance

When formulating inks for printed batteries, several practical aspects must be considered. These include the ink's rheology, wettability, potential atmospheric contamination, and particle size. Ensuring the ink's properties are suited to the chosen printing method and substrate is crucial for achieving consistent performance.

The performance of printed batteries is influenced by their chemistry. Zinc–manganese batteries face challenges in recharging due to irreversible reactions and potential dendrite formation. NiMH batteries, while safer, still struggle with gas evolution during operation. Lithium-ion batteries, despite their high cycling stability, require stringent moisture control, complicating their use in printed formats.

Mechanical reliability is another critical factor, especially for flexible applications. Using flexible substrates and innovative current collector designs can mitigate mechanical failure during bending. In the rapidly evolving world of energy storage, printed batteries have emerged as a revolutionary technology with the potential to transform how we power our devices. From their inception with Akuto and Ogata's printed lead-acid battery to the latest advancements, the field has seen significant breakthroughs, promising a future where flexible, aesthetically versatile, and high-performing printed batteries are commonplace.

The Evolution and Current State of Printed Batteries

Printed batteries leverage advanced printing techniques to create thin, flexible energy storage devices. Lithium-ion chemistry dominates the landscape, primarily focusing on printed electrodes. However, printing electrolytes remains a challenge due to stringent process requirements to avoid contamination. While academic research has made strides in demonstrating the feasibility of processing battery materials into inks and printing them, practical applications often fall short due to insufficient electrochemical performance.

Despite these challenges, the promise of printed batteries lies in their potential benefits, particularly their flexibility and adaptability to various geometric forms. This versatility makes them ideal for applications in flexible electronics, wearable devices, and other innovative technologies.

Aesthetic Versatility: Beyond Traditional Forms

One of the exciting aspects of printed batteries is their aesthetic versatility. Techniques like stencil, transfer, flexographic, and dispenser printing have been used to create batteries in various shapes, including complex 3D forms. For instance, Sun et al. demonstrated 3D-printed lithium titanate (LTO) anodes and lithium iron phosphate (LFP) cathodes, although the process required high-temperature sintering, limiting substrate choices.

Dispenser printing, adapted for 3D printing, allows the creation of intricate battery architectures, offering significant form-factor freedom. This method, although slower, is superior for shaping batteries with complex geometries. Meanwhile, screen and stencil printing methods enable faster production and are suitable for thick-layer deposition, crucial for achieving higher areal capacities.

Flexibility: Redefining Battery Applications

Flexibility in printed batteries encompasses stretchability, bendability, and foldability. This attribute is vital for integrating batteries into flexible electronics and wearables. Gaikwad et al. developed flexible zinc–manganese batteries capable of maintaining their performance under various bending stresses, highlighting the potential for such batteries in dynamic environments.

Dynamic and static bending tests have demonstrated that flexible printed batteries can retain significant capacity even after extensive bending cycles. This flexibility opens up new possibilities for energy storage in applications where traditional rigid batteries would fail, such as in smart textiles and flexible displays.

Enhancing Electrochemical Performance

For printed batteries to become viable alternatives to conventional batteries, they must achieve high areal capacities and low internal resistance. Recent studies have shown promising results, with some printed batteries achieving areal capacities sufficient to power small electronic devices. However, challenges remain, particularly in achieving low internal resistance to meet high-power demands.

Innovations in materials and printing techniques are crucial. For example, Sun et al.'s 3D rechargeable batteries and Kang et al.'s laminated lithium-ion batteries have shown that with the right materials and designs, printed batteries can achieve the necessary performance metrics. Yet, issues like moisture contamination during printing and the need for air-stable electrolytes must be addressed to realize their full potential.

The Future: Roll-to-Roll Manufacturing

Roll-to-roll (R2R) manufacturing is often touted as the ultimate goal for printed batteries, promising high-throughput and cost-effective production. However, few examples exist of fully R2R-manufactured batteries. Wang et al. made significant strides by developing a manganese dioxide (MnO2) ink suitable for R2R flexographic printing, demonstrating the feasibility of this approach.

The transition to R2R manufacturing involves overcoming several technical hurdles, including ensuring the compatibility of all battery components with the R2R process and maintaining high electrochemical performance. Success in this area would mark a significant milestone, making printed batteries a mainstream technology.
