At the Realme Fan Festival held today, realme officially announced a concept phone with a battery capacity of 15,000mAh.Judging from the latest official announcement, this mobile phone is the world’s first all-silicon anode battery created by realme and Zhuhai Guanyu.

The 15000mAh capacity battery built into the mobile phone has the No. 1 energy density. The high-capacity battery cathode material and solid electrolyte of up to 1200Wh/L ensure sufficient battery energy storage and efficient ion transmission. The battery energy density is more than 1.3 times that of traditional silicon-carbon negative electrode batteries.

Although the battery capacity is so large, the body of this phone is only 8.89mm (mini diamond structure), unlocking the achievement of the world's narrowest Android motherboard, with a width of only 23.4mm.

According to the official statement, the 45W fast charging 20000mAh mobile power supply with 3C certification will be released in September together with the Realme 15 series.
