Revolutionary third-generation silicon-carbon battery: HONOR takes the lead in smartphone battery innovation

Today, smartphones are an indispensable productivity tool, and battery life is essential for users who need to rely on their devices. Constantly committed to human-centered innovation, HONOR recognizes this need and strives to further advance battery technology to enhance the smartphone experience and enable users to maximize their productivity.



With this goal in mind, HONOR embarked on a groundbreaking development of battery technology that goes beyond what the traditional smartphone industry offers. In the age of artificial intelligence, devices require more processing power and battery, all in a thinner and lighter package. HONOR understands that traditional battery solutions are no longer enough, and since the launch of the HONOR Magic5 series, the company has taken the lead in the development of silicon batteries with high silicon and carbon content. It develops ultra-thin, long-lasting smartphones that set new industry standards. This revolutionary technology, which is the brand new third-generation silicon-carbon battery in HONOR Magic V3, provides exceptional battery life and reliable performance even in harsh cold conditions. By leveraging these remarkable advances, HONOR aims to change user expectations and offer them greater productivity and unmatched convenience.

Use of silicon-carbon material to increase battery capacity

Lithium batteries have long served as the primary power source for smartphones, with their performance largely dependent on the amount and flow of lithium ions. One of the decisive factors that affect the amount of lithium ions is the anode material. The preferred and widespread material for the production of anodes is graphite, which offers a theoretical capacity of 372 mAh/g(1). However, to increase the capacity of its batteries, HONOR uses a silicon-based material in the production of anodes, which boasts a staggering theoretical capacity of 4,200 mAh/g(2)which is ten times more than graphite.

Considering the huge potential of silicon-based anode material capable of receiving lithium, HONOR has effectively used its capabilities to develop its battery technology. By integrating silicon and carbon materials, HONOR was able to create a robust and high-performance electrochemical structure. Based on this success, HONOR has developed a high-end third-generation silicon-carbon battery for HONOR Magic V3, which increases the proportion of silicon in the negative electrode to 10%.(3) Remarkably, it achieves this with an average battery thickness of only 2.6 mm(4). Compared to Magic V2, HONOR Magic V3 has reduced battery thickness by 4.4%(5) and at the same time achieved an increase in energy density by 5.74%.(6)

Inspired by Tesla’s progress

In 2016, Tesla introduced the Model 3, an entry-level electric car powered by an innovative battery with an improved silicon composition. This increase in silicon increased the energy density to around 550 mAh/g, which greatly improved the overall performance of the battery. Inspired by Tesla’s progress, HONOR’s R&D team delved into the potential of silicon-based chemical structures to deliver an optimal solution for smartphone users. In terms of battery capacity, the third-generation silicon-carbon batteries surpass the latest graphite-based batteries, showing an exceptional capacity of 5,150 mAh(7). In addition, by integrating the Power Enhanced discrete chip and the HONOR E1 power management system, this battery shows a substantial improvement in performance at both normal and low temperatures. As a result, users can expect consistent and reliable battery performance in any environment, further cementing HONOR’s position at the forefront of battery technology.

Increased battery performance and power management with the HONOR E1 Power Enhanced chip

The inclusion of the HONOR E1 discrete chip significantly improves power management efficiency and battery performance. This patented chipset is a special three-in-one design that seamlessly integrates energy meters, protection and anti-counterfeit ICs into one compact unit. While maintaining the dimensions of its predecessor’s battery protection board, the HONOR E1 chipset remains incredibly small and thin and provides unmatched functionality.

One of the outstanding capabilities of the HONOR E1 Power Enhanced chip is the intelligent discharge solution, which brings remarkable improvements in charging and battery discharge efficiency. By intelligently recognizing different temperature and charging scenarios, the chipset optimizes the charging process to achieve a more complete battery charge, while increasing the discharge efficiency to alleviate the battery aging problem. Compared to the existing solution without a discrete power management chipset, the Power Enhanced HONOR E1 chip further optimizes the discharge efficiency and enables an additional 3%(8) accuracy in power management. This accuracy extends to low battery levels, where current monitoring is more accurate, resulting in more efficient discharge. In addition, the chipset adjusts the discharge speed according to different scenarios, effectively extending the discharge time when the battery is almost empty.

The chipset also integrates a customized low-temperature algorithm that optimizes battery performance in extreme conditions. To overcome compatibility issues, HONOR has developed a battery algorithm specially adapted for this technology, which significantly improves the accuracy of battery capacity calculations, ensures accurate power management and maximizes overall efficiency.

Enhancing battery reliability using carbon fiber material

HONOR Magic V3 stands out on the market as a foldable smartphone with the highest battery-to-device ratio. By integrating silicon-carbon materials, the third-generation silicon battery represents a significant advance in size and thickness, setting a new standard with an incredibly thin average battery profile of just 2.6mm. However, the challenge is to maintain the reliability of the battery due to its larger and slimmer dimensions and ultra-thin profile. The conventional approach of using an aluminum alloy protective chamber does not meet the reliability requirements in such a thin design.

HONOR solves this problem with a breakthrough step by using carbon fiber as the material for the protective battery chamber. This innovative choice offers several advantages, including lighter weight, less thickness and greater reliability than is common with traditional aluminum alloy. Notably, this is the industry’s first extensive use of carbon fiber material, with carbon fiber covering almost a third of the area under the screen. This implementation ensures increased battery reliability and reinforces HONOR’s commitment to pushing technological boundaries.

Summary

With its third-generation silicon-carbon battery, HONOR has taken the lead in battery innovation in the smartphone industry, demonstrating its commitment to technological breakthroughs. The introduction of this advanced battery technology is a significant milestone that offers users extended battery life, allowing them to stay connected and productive for long periods of time. HONOR’s adoption of silicon-carbon technology underscores its commitment to delivering exceptional smartphone experiences and redefining industry standards for smartphone batteries. This innovative approach pushes smartphone technology forward, providing users with a more powerful and reliable experience.
