How Prominent Micro Battery Trends Transform the Landscape of Industry?

Highlights:

• Introduction
• Trends in micro batteries
• Applications of micro batteries in IoT
• Key product launches and partnerships

With a footprint of a few square millimeters or less, micro batteries are miniature batteries designed for small electronic systems or devices. These batteries are used in devices that have shortage of space due to their limited size. They have applications in devices such as hearing aids, sensors, medicine implants, and other microdevices as these devices have space limitations.

Moreover, button batteries belong to the category of micro batteries and are used in electronic devices that require less power to run. Owing to their long shelf life, the button battery sector is anticipated to generate an absolute revenue growth of $138.0 million by 2032.

Which prominent micro battery trends have gained popularity?

To optimize performance and efficiency, key manufacturers invest in R&D initiatives to develop new battery shapes and structure patterns. In addition, the electrode structure parameters such as porosity and thickness are adjusted via on-chip integration to increase specific surface area and decrease resistance.

• The latest manufacturing techniques:

The advancement of innovative manufacturing technologies, such as laser processing and holographic lithography, has significantly enhanced the power performance of micro batteries. These improvements allow integration of high-volume fractions of high-capacity materials into primary micro batteries. The utilization of holographic lithography ensures precise on-chip integration of micro-batteries, providing exceptional control over the structural parameters of electrodes. This high level of control facilitates the customization of micro-batteries to meet specific power requirements.

• On-chip integration:

The integration of micro-battery technology directly on chips results in more efficient designs, offering space-saving benefits and cost reduction. This is vital for ultrathin wearable devices such as smartwatches and smart eyewear, which require small and flexible batteries for operation. Integration of micro-batteries into the design of such devices ensures a consistent power supply, guaranteeing power availability when needed. On-chip integration plays a pivotal role in providing a stable voltage supply, contributing to the maintenance of reliable real-time data.

Contribution of micro batteries in IoT (Internet of Things):

Internet of Things (IoT) is an emerging technological application, and various IoT devices rely on the use of micro batteries to deliver electric power. Conventional cylindrical batteries are often unsuitable for the small dimensions of IoT devices. As a result, micro batteries have become the preferred choice for powering IoT devices.

Manganese dioxide lithium batteries are widely used as primary batteries in various applications, such as tire pressure monitoring systems in cars and backup power sources for IoT & memory devices. These batteries are valued for their high voltage, high energy density, and lightweight characteristics as they have a battery voltage of 3V, nearly double the alkaline batteries.

A growing landscape of the Indian micro battery sector:

The Indian government offers incentives, including tax exemptions and subsidies, to promote the expansion of the lithium-ion battery manufacturing sector. Moreover, substantial government investments in solar energy and battery storage solutions have contributed to the growth of the sector. In addition, private organizations invest in advanced micro battery technologies. Hence, the Indian micro battery industry is anticipated to display a notable CAGR of 23.6% during the forecast period from 2023 to 2032.

How do the top entities dominate the micro battery sector with novel strategies?

In recent years, there has been a significant expansion in the micro battery industry with many companies competing to increase their presence in the sector. Micro battery businesses have entered strategic alliances through mergers, acquisitions, and partnerships to gain a competitive edge. For instance, in November 2023, a digital health company specializing in sensor-enabled technology, Injectsense Inc., collaborated with Injectpower, a developer of ultra-miniature solid-state micro-batteries for medical applications, and secured a funding of $9.4 million. The funding is expected to produce highly integrated autonomous implantable devices, each smaller than a grain of rice.

On the other hand, at Electronica, the premier trade fair and conference for electronics in 2022, VARTA displayed its newest product, the A5 version, as the latest addition to its highly successful CoinPower range. CoinPower Rechargeable lithium-ion cells in a small format have high energy and are the preferred choice of several key manufacturers. The A5 generation cells are designed to be compatible with TWS headphones and are well-aligned with the current trend of gaming TWS Earbuds. They cater to the needs of wearables and IoT devices, offering consumers a high level of convenience across these product categories.

To conclude, micro batteries are vital components of energy storage systems in IoT devices and wearables. Moreover, on-chip integration and the latest manufacturing techniques shape the future of the sector. Key players invest in R&D activities and form alliances to discover advanced battery technologies. However, a rise in the integration of micro batteries in small textiles is expected to open new avenues for the industry in the upcoming years.
