On August 28th, according to Kuaikeji, realme officially unveiled its concept smartphone with a 15000mAh battery capacity at the realme Fan Festival today.
The company has collaborated with Global Power Manufacturer, Guanhua, to develop a groundbreaking, world-first all-silicon anode battery technology for this device.
The integrated 15000mAh battery boasts the highest energy density in its class, reaching an impressive 1200Wh/L. This advanced battery utilizes high-capacity cathode materials and solid electrolytes, ensuring ample energy storage and efficient ion transport. Its energy density is reportedly over 1.3 times greater than traditional silicon-carbon anode batteries, a significant leap forward in battery technology.
Despite its substantial 15000mAh capacity, this innovative smartphone maintains a remarkably slim profile, measuring just 8.89mm thick. This is achieved through a “mini diamond structure,” which also enables the global achievement of the narrowest Android motherboard, with a width of merely 23.4mm. This design showcases a commitment to balancing large battery capacity with a sleek and ergonomic form factor.
Furthermore, realme announced that its 45W fast-charging 20000mAh mobile power bank, featuring 3C certification, will be released alongside the realme Number Series in September. This complementary accessory would provide users with a convenient and powerful solution for on-the-go charging, enhancing the overall user experience.
