Discover the Revolutionary Third-generation Silicon-carbon Battery: Setting New Standards with Advanced Power Management Chip from HONOR

Riyadh – Kingdom of Saudi Arabia, September 30, 2024: Today, smartphones have become indispensable tools for enhancing productivity, and battery life plays a crucial role for consumers who rely on their devices for extended periods. With a steadfast commitment to human-centric innovations, HONOR understands the significance of prolonged battery life for users. By continuously investing in battery technology, HONOR strives to expand the capabilities of smartphones, empowering users to maximize their productivity.

With this in mind, HONOR has embarked on groundbreaking advancement in battery technology, going beyond what the traditional smartphone industry has offered. In the age of AI, devices require greater computational power and battery performance, all within a slimmer and lighter package. Understand that traditional battery solutions are no longer sufficient to meet these evolving needs, HONOR has taken the lead in developing silicon-carbon batteries with high silicon content since the release of the HONOR Magic5 Series, consistently developing ultra-thin and long-lasting smartphones that set new industry standards. Introducing the all-new Third-generation Silicon-carbon Battery in the HONOR Magic V3,  this revolutionary battery technology delivers exceptional battery life and reliable performance, even in challenging low-temperature environments. By harnessing these remarkable advancements, HONOR aims to redefine user expectations, offering users enhanced productivity and unparalleled convenience.

Harnessing Silicon-carbon Material for Enhanced Battery Capacity

Lithium batteries have long served as the primary power source for smartphones, with their performance being heavily dependent on the amount and flow of lithium ions. One crucial factor influencing the quantity of lithium ions is the anode material. Graphite has been widely adopted as the material of choice for anodes in batteries, offering a theoretical capacity of 372mAh/g[1]. To enhance the capacity of its batteries, HONOR incorporates a silicon-based material for its anodes, which boasts a staggering theoretical capacity of 4200mAh/g[2], or 10 times that of graphite.

Given the immense potential of silicon-based anode material to take lithium, HONOR has effectively harnessed its capabilities to advance its battery technology. Through the integration of silicon-carbon materials, HONOR has successfully established a robust and high-performance electric chemical structure. Building on this achievement, HONOR has developed the industry-leading Third-generation Silicon-carbon Battery for the HONOR Magic V3, boosting the proportion of silicon in the negative electrode to 10%[3]. Remarkably, it accomplishes this while boasting a sleek average battery thickness of 2.6mm[4], resulting in a lighter yet stronger battery performance. Compared to the Magic V2, the HONOR Magic V3 has a battery thickness reduced by 4.4%[5] while achieving a 5.74%[6] increase in energy density.

In 2016, Tesla unveiled the Model 3, an entry-level electric vehicle powered by an innovative battery with a silicon-enhanced composition. This addition boosted the power density to approximately 550mAh/g, significantly improving overall battery performance for drivers. Inspired by Tesla’s advancement, the HONOR R&D team delved into the potential of silicon chemical structures, aiming to deliver optimal solutions for smartphone users. In terms of power capacity, the Third-generation Silicon-carbon Battery surpasses the latest graphite-based batteries, showcasing an exceptional battery capacity of 5150mAh[7]. Furthermore, by integrating the Power Enhanced Chip HONOR E1 and a power management system, this battery demonstrates substantial improvements in both normal and low-temperature performance. As a result, users can expect consistent and reliable battery performance in any environment, further solidifying HONOR’s position at the forefront of battery technology.

Elevating Battery Performance and Power Management with Power Enhanced Chip HONOR E1

The embedding of the HONOR E1 greatly improves power management efficacy and battery performance. This proprietary chipset presents a special three-in-one design, which seamlessly integrates the energy meter, protection and anti-counterfeit integrated circuits into a single compact unit. Retaining the dimensions of its predecessor’s battery protection board, the HONOR E1 chipset remains incredibly small and thin, delivering unmatched functionality.

Benefitted by the HONOR E1, the Third-generation Silicon-carbon Battery introduces an innovative Smart Discharging Solution, revolutionizing battery charging and discharging efficiency. By intelligently recognizing various temperatures and charging scenarios, the chipset optimizes the charging process to achieve a more complete battery charge while efficiently discharging the battery to combat battery aging issues. Compared to existing solutions that do not have a standalone power management chipset, the HONOR E1 further enhances discharging efficiency, achieving an additional 3%[8] accuracy in power management.  This precision extends to low battery conditions, where current monitoring becomes more accurate, thereby delivering a more efficient discharging. Additionally, the chipset adapts the discharging rate according to different scenarios, effectively extending the duration of low battery discharging.

Furthermore, the chipset includes a customized low-temperature algorithm, which elevates battery performance even in the most extreme conditions. In light of compatibility challenges, HONOR has developed a battery algorithm, resulting in a significant improvement in the accuracy of battery capacity calculations. This ensures precise power management and maximizes overall efficiency.

Strengthening Battery Reliable with Carbon Fiber Material

The HONOR Magic V3 stands out as the foldable device with the highest battery-to-device ratio in the industry. With the integration of silicon-carbon materials, the Third-generation Silicon Battery showcases significant advancements in size and thickness, setting a new industry benchmark with an astonishingly thin average battery profile of just 2.6mm. However, the challenge lies in maintaining the reliability of the battery, given its larger and thinner dimensions, as well as the ultra-slim profile of the device. The conventional approach of using an aluminum alloy protection chamber does not meet the reliability requirements within such a slim form factor.

To address this concern, HONOR takes a groundbreaking step by adopting carbon fiber as the material for the battery protection chamber. This innovative choice offers several advantages, including being lighter, thinner, and more reliable than traditional aluminum alloy. Notably, this marks the industry’s first extensive utilization of carbon fiber material, with carbon fiber covering nearly one-third of the area below the screen. This implementation ensures enhanced battery reliability and reinforces HONOR’s commitment to pushing technological boundaries.

Summary

With its Third-generation Silicon-carbon Battery technology, HONOR has once again taken the lead in battery innovation within the smartphone industry, underscoring its commitment to technological advancement. The introduction of this advanced battery technology marks a significant milestone, offering users extended battery life and enabling prolonged connectivity and productivity. HONOR’s use of silicon-carbon technology highlights its dedication to delivering superior smartphone experiences and setting new industry benchmarks. This innovative approach propels smartphone technology forward, providing users with a more powerful and reliable experience.
