Recently, Haopeng Technology and the Dutch silicon materials supplier LeydenJar Technologies announced the formal establishment of a deep strategic partnership to jointly develop and produce a new generation of 100% pure silicon anode batteries with high energy density.
This cooperation marks a potential breakthrough in battery technology in the consumer electronics field and provides new energy solutions for the rapidly emerging AI terminal devices.
Tackling the Challenge: "Battery Anxiety" in AI Hardware
Against the backdrop of AI becoming the new round of industrial revolution, AI-side consumer electronic products are experiencing explosive growth. From AI glasses, AI headphones, AR/VR/MR devices, to the soon-to-be widely deployed home and commercial robots, and drones in the low-altitude economy, these emerging terminals have higher requirements for battery performance.
These devices not only need longer battery life but also have strict standards for battery safety and form factor adaptability.
The energy density of traditional graphite anode batteries is nearing theoretical limits, making it difficult to meet the energy demands of the next generation of AI devices.
Haopeng Technology's Chief Technology Officer, Liao Xingqun, pointed out: "The enormous energy demands of AI are continuously challenging the power limits of current edge devices, and energy density is one of the key parameters determining the success or failure of the next generation of consumer electronic products."
Strong Alliance: From Memorandum of Understanding to Deep Cooperation
This strategic cooperation between Haopeng Technology and LeydenJar was not a sudden decision. As early as the end of 2024, both parties signed a Memorandum of Understanding, focusing on the next generation of high energy density battery supporting technology for a leading wearable brand customer in North America.
At that time, the goal set by both parties was to develop 100% pure silicon anode lithium-ion battery products that meet customer needs.
This deep strategic cooperation will accelerate the development and application of 100% pure silicon anode battery solutions in more brand customers' AI+ edge scenarios.
This collaboration represents another key practice for Haopeng Technology to accelerate its strategy of becoming a leader in "AI+ edge new energy solutions."
Christian Rudd, CEO of LeydenJar, stated: "We are no longer just talking about possibilities; LeydenJar and Haopeng Technology have teamed up to mass-produce thousands of batteries and deliver them to leading global consumer electronics brands."
Technical Breakthrough: Performance Advantages of Pure Silicon Anodes
What advantages does a 100% pure silicon anode have compared to the currently mainstream graphite anodes?
In simple terms, the ability of silicon materials to store lithium ions far exceeds that of graphite. The theoretical specific capacity can reach about ten times that of graphite, which means that pure silicon anode batteries can store more energy in the same volume.
According to data released by both parties, 100% pure silicon anodes can store more energy than standard graphite anodes. Haopeng Technology has innovatively combined this material with application scenarios, thereby increasing the overall energy density of the battery by at least 50%.
More specific data comes from laboratory tests: 100% pure silicon anode batteries have completed 500 cycle tests in an environment without any external pressure, achieving an energy density target of 1350Wh/L.
This figure is significantly higher than the energy density levels of ordinary lithium-ion batteries currently on the market.
For comparison, the energy density of the all-silicon anode battery mentioned in a recent concept phone by realme is 1200Wh/L, while Haopeng Technology's pure silicon battery has an even higher energy density of 1350Wh/L.
Innovative Design: Balancing Energy Density and Safety
Achieving high energy density is just one of the challenges faced by pure silicon anode batteries. More critically, it is how to ensure the battery's cycle life and safety while enhancing energy density.
Silicon materials exhibit significant volume expansion and contraction (up to about 300%) during charging and discharging, which has always been a major technical barrier to the application of silicon anodes.
To address this issue, Haopeng Technology has employed innovative battery design and manufacturing technologies to ensure that capacity increases can be reliably achieved while maintaining stable cycle life and safety, enabling large-scale production.
Liao Xingqun explained: "By applying LeydenJar's 100% pure silicon anode in Haopeng's advanced battery structure, we can achieve breakthrough energy efficiency levels without sacrificing cycle life or safety."
Commercialization Process: Roadmap from Prototype to Mass Production
In terms of commercialization progress, both parties have already achieved substantial results. Currently, they have manufactured thousands of prototype batteries through a small-scale production assembly line and have delivered them to leading global consumer electronics customers for testing.
Meanwhile, both parties are accelerating mass production verification on Haopeng Technology's smart manufacturing production line.
It is expected that with the synchronous support of LeydenJar's Plant One factory, the commercial mass production of 100% pure silicon anode batteries produced by Haopeng Technology is anticipated to fully commence in 2027.
This timeline provides clear guidance for the product planning of consumer electronics brand manufacturers and suggests that 2027 could become the inaugural year for the large-scale commercialization of pure silicon anode batteries in the consumer electronics field.
Market Outlook: Vast Space for AI+ Edge Applications
With outstanding product quality and strong technological innovation capabilities, Haopeng Technology has established long-term strategic partnerships with well-known domestic and international companies such as HP, Dell, Microsoft, Sony, Google, and DJI.
These high-quality customer resources provide a market foundation for the mass promotion of pure silicon anode battery products.
In application areas where space is extremely limited and high endurance is required, such as AI+ edge hardware, enhancing energy density with silicon anodes is an inevitable development trend.
As a top global battery supplier in the AI+ edge field, Haopeng Technology is actively exploring advanced battery technologies such as semi-solid, solid-state, and pure silicon anodes, and is at the forefront of commercialization progress in the industry.
In addition to pure silicon anode batteries, Haopeng Technology is also making strides in the semi-solid and solid-state battery fields. According to company disclosures in March 2025, their semi-solid batteries can achieve a volumetric energy density of 950Wh/L, with a cycle life of over 500 weeks, and have passed relevant safety tests such as puncture and overcharging.
Meanwhile, solid-state batteries are expected to provide sample verification to the market as early as this year.
Industry Significance: Redefining Consumer Electronics Endurance Standards
The maturity of pure silicon anode battery technology will have a profound impact on the design of consumer electronic products.
Higher energy density means that longer battery life can be provided in the same battery volume or that the battery volume can be reduced under the same endurance requirements, leaving more space for other components.
This is particularly important for emerging product categories with limited space, such as AI wearable devices and AR/VR glasses.
Analysis referencing data from the realme concept phone indicates that a full-silicon anode battery could support a smartphone to last five days on a single charge.
While actual performance may vary by device, this indeed showcases the potential of pure silicon anode batteries in extending device endurance.
Global consumer electronics brands are closely monitoring this technological advancement. Thousands of prototype batteries have been sent to leading global consumer electronics customers for testing.
If everything goes as planned, we may witness the commercial mass production of pure silicon anode batteries in 2027, at which point the endurance experience of products such as AI glasses, AR/VR devices, and smart wearables may undergo a qualitative leap.
Innovation in battery technology never stops, and each breakthrough may redefine the boundaries of electronic products.
