Why Silicon-Carbon Batteries Are Changing Smartwatches | Image Source: www.androidauthority.com
SEATTLE, Washington, April 7, 2025 – In the ever-changing landscape of usable technology, battery was an obstacle. Despite cutting-edge exhibitions, powerful chipsets and increasingly elegant designs, smart watches always require daily or almost daily loads. This can soon become something of the past, thanks to the silent but impressive arrival of Silicocarbon battery technology, an advance that promises sustainable, slower and greener devices.
According to Android Authority, OnePlus Watch 3 is one of the first commercial smart watches to implement this new battery chemistry. Although not perfect - with a slightly bulky shell and a stained heart rate monitoring - it marks an important leap forward with its battery 631m. This is a 26% increase in your predecessor and offers a verified five-day battery. And this is just the beginning.
What makes special carbon silicone batteries?
Silicon-carbon batteries are not just lithium-ion units. Magic is in its structure. Traditional lithium ion batteries use graphite anodes, while silicacarbon variants incorporate silicon, which may contain significantly more lithium ions. This higher energy density means that more energy is stored in the same or even smaller physical footprint.
As Group14 Technologies, the leader in this space, has said, its patented SCC55 ® material mixes silicon with hard carbon, resulting in batteries that charge 0-80% in less than 10 minutes and last up to 50% longer than conventional lithium ion batteries. According to Grant Ray, the company’s vice-president of global market strategy, SCC55® is already sending hundreds of manufacturers around the world in bulk, doing everything from electric vehicles to AI-compatible mobile phones.
Why do smart watches need better batteries?
Let us be realistic: the modern smart watch is a wonder of engineering. Track metric health, report, provide GPS navigation, synchronization with smartphones and even make calls – all from your wrist. However, it often fails in a fundamental area: keeping power enough to do all these things coherently.
The problem becomes obvious when users are forced to remove their watches at night to recharge. This is not only a nuisance, but also to interrupt vital features such as sleep monitoring, heart rate monitoring and emergency alerts. A smart wristwatch is essentially useless. Therefore, the value proposition of a transportable silicocarbon is immediately convincing: more time on your wrist, less time with a charger.
What other devices use silicone-coal technology?
Innovation is not limited to smart watches. According to the Hindu Times, several flagship smartphones have already adopted this technology. Find Vivo X8 Ultra packed a 6,100mAh carbon-silicocarbon battery in an elegant chassis, and the iQOO Z10 goes further with a 7300m Ah unit, all holding a weight less than 200 grams. This shows the flexibility of Silicocarbon batteries thanks to different shape factors and use cases.
Redmi 14 Pro Plus’s rating is another notable example, combining a substantial battery with a thin profile. These phones show how technology can balance performance and portability, a balance that has escaped many devices in the past. They also point out that Silicocarbon batteries are more than experimental, they are commercially viable, already in the hands of consumers, and here to stay.
Q Pulmamp: A: What does this mean for the future of fabrics?
Q: Will the other smartwatch brands soon take batteries of silicocarbon?A: While brands like Apple, Google and Samsung have not yet adopted technology, the industry’s momentum suggests that they monitor closely. These companies do not necessarily need to take the initiative, given their field, but the first engine among them could gain goodwill by solving a key point in the pain of users.
Q: Are there any disadvantages in silicocarbon batteries?A: Yes, there is compensation. According to the ideas of Android Authority and battery experts, these batteries can experience swelling and can be degraded faster under certain conditions. Excessive use of silicon to boost capacity could also reduce longevity, which means manufacturers will have to balance energy benefits with sustainability.
Q: Can this technology lead to a thinner smart watch?A: Absolutely. Higher energy density means that manufacturers can reduce the shape factor without sacrificing battery life. It is a win-win for consumers who prefer discreet and comfortable clothes that do not look like mini bricks on their wrists.
Q: What is the ecology of these batteries?A: More than your lithium ion predecessors. Carbon silicon batteries produce less harmful by-products and are easier to recycle. Their low environmental footprint makes it a more sustainable option for technology manufacturers.
Group 14 battery switch
The group14 SCC55 ® is not only a battery material, it is an innovation platform of all kinds. Developed to meet the dual challenge of energy density and load speed, the material replaces graphite without requiring manufacturers to reconfigure their production lines. This compatibility is a game change.
The company operates in an applied innovation model that combines product and process innovation. Instead of focusing exclusively on laboratory progress, they have built progressive modular BAM (Active Battery) plants that can remove massive volumes of SCC55 ® efficiently. According to Ray, its Washington-based BAM-1 plant has been operating since 2021, while a South Korean JV plant began to be sent in 2024. BAM-2, which is expected to be the largest in the world, will soon add 2,000 tons of annual capacity.
This level of production does not only support consumer electronics; it supplies electric vehicles, eVTOL and AI@-@ Heavy data centres. As the AI workloads stop the energy capacity of the traditional infrastructure, the Silicocarbon batteries offer faster load and better state-of-the-art resistance, ideal for calculating modern edges and data centers.
Industrial impacts: Who wins and who waits?
Smart money is in the first adopters. While brands like Samsung and Apple can afford to wait, smaller or more challenging players like OnePlus and Vivo use this technology as a lever to differentiate. And it works. Both evaluators and users take note of the longer battery life and slower profiles, both of which strongly influence purchasing decisions.
More importantly, consumer expectations are changing. Once people live the battery for several days without the fat, it will be difficult to return. And since OLED screens and high frequency rates have become essential, the battery life extended through the silicocarbon could become the next point of reference for the consumer.
The way to go: Where are we going?
The change will not happen overnight. Inherited supply chains, existing design limitations and product roadmaps mean that lithium ion batteries do not disappear soon. But the road is clear. With the increase in Gloss14 materials, costs will decrease, integration will improve and resistance to adoption will disappear.
For consumers, this means a new era of smart watches that are more reliable, less intrusive and really smart about how they manage power. For industry, this is a call for evolution or risk of dropping.
As we look at 2026 and beyond, we hope to see the influence of Silicocarbon batteries spread into more devices: lighter phones, durable wear, greener EV and more sensitive on-board computer systems. The battery revolution may not come with fireworks, but it’s here, shaking quietly under his wrist, and it’s a powerful thing.
