By leveraging these advancements, Honor aims to redefine user expectations and deliver enhanced productivity and convenience, reshaping the smartphone industry by setting new standards for innovation.

Lithium batteries have long been the dominant choice in the smartphone market. The capacity and charging rate of these batteries are directly influenced by the amount and flow rate of lithium, and a critical factor in determining the amount of lithium ions is the selection of negative electrode material. Typically, graphite has been the commonly used negative electrode material, offering a theoretical capacity of 372mAh/g. However, Honor has taken a significant leap forward by incorporating silicon-based negative electrode material.

The theoretical capacity of a pure silicon-based anode stands at an impressive 3579mAh/g, which is 10 times more than that of graphite. However, the pure silicon-based material has an extremely exaggerated volume expansion rate of up to 300%, which might easily cause damage to the battery and the phone. Meanwhile, in terms of the battery life cycle, pure silicon-based electrodes are far lower than graphite-based electrodes, due to the particle pulverization and structural collapse of the silicon material caused by the huge volume change.

Recognizing the enormous potential of silicon-based anode material to deliver way better electron adsorption, Honor has harnessed its power to enhance its battery technology, building up a stable while powerful electric chemical structure with silicon-carbon material. Proudly standing as the first smartphone manufacturer to apply silicon-carbon battery technology, Honor first introduced the Silicon-carbon Battery in the HONOR Magic5 Pro. Building upon this success, Honor has now upgraded the battery, bringing the industry-leading Second-generation Silicon-carbon Battery to the Honor Magic 6 Series.

Traced back to 2016 when Tesla announced the Model 3, the entry-level EV powered by the all-new battery innovation, with a certain percentage of silicon added, the power density can be boosted up to roughly 550 mAh/g, promising an overall improved battery performance to drivers. Likewise, the Honor R&D team also conducted in-depth learning from the silicon chemical structure, aiming at delivering the best solutions to smartphone users, the Second-generation Silicon-carbon Battery boasts a far more here concentration of power capacity compared to the latest graphite-based battery, pushing the boundaries of battery capacity to an extraordinary 5600mAh.

By integrating the Power Enhanced Chip Honor E1 and a power management system, this battery demonstrates significant improvement in both normal-temperature and low-temperature performance. Thanks to these advancements, HONOR ensures that users enjoy a more stable battery performance in various conditions, solidifying its position at the forefront of battery technology. HONOR believes, the advanced silicon-carbon battery technology will be utilized widely not only in smartphone industry, but also EV giant Tesla.

Revolutionary Enhancements in Silicon-Carbon Battery Technology

The utilization of the latest high-density silicon-based anode material brings a host of compelling benefits. By incorporating Nanostructured Silicon-carbon material and implementing a Porous Carbon Nanostructure, the battery’s stability is enhanced through increased carbon coating and lessened silicon carbide particles. This improvement leads to enhanced cycling efficiency and reduced expansion behavior, ensuring a more reliable battery performance.

Through revolutionary advancements in underlying materials and manufacturing processes, the Second-generation Silicon-carbon Battery achieves remarkable improvements in power density and fast-charging capabilities. Compared to other latest graphite batteries available during the same period, the HONOR Magic6 Series has achieved an impressive 6.0% increase in power density. By utilizing a targeted silicon-carbon binder, the silicon particles are enveloped by new lithium-rich binder groups, resulting in a directionally distributed coverage that enhances the Li+ transmission capability of the silicon-based anode and effectively improves the charging rate. Using the HONOR Magic6 standard version as a sample, under the same fast charging spec, the HONOR Magic6 has seen a notable increase of 2.1% in power density.

Moreover, the innovative Microtunneling Laser Guidance Technology is incorporated into silicon-based anode. This technology significantly increases the contact area between the electrolyte and the silicon-based anode, creating new ion transport channels and tapping into the usable capacity in the low-voltage range of the silicon-based anode, thereby comprehensively elevating the power density of the battery. Thanks to this technology, HONOR Magic6 Series packs with a further enhanced fast charging capability without compromising a bit on the power density. Compared to the last generation, the HONOR Magic6 Series elevates the fast-charging performance from 66W to an impressive 80W.

Power Enhanced Chip HONOR E1: Empowering Battery Performance and Power Management

The Second-generation Silicon-carbon Battery is powered by the Power Enhanced Chip HONOR E1, bringing significant advancements in power management and battery performance. This proprietary chipset features a unique three-in-one power management design, combining the energy meter, protection and anti-counterfeit integrated circuits into a single compact unit.
