With the continuous advancement of lithium battery technology, the range anxiety of high-end new energy vehicles has been effectively addressed. Silicon-based negative electrode materials have played a crucial role in this. Batteries utilizing this technology not only achieve higher capacity but also have smaller volumes, making them the preferred choice for many new energy vehicles. Now, this technology is also beginning to be popularized in the field of mobile phone batteries.

Following in the footsteps of Honor and Vivo, OPPO has also started developing large batteries with silicon negative electrode technology. According to some tech bloggers, OPPO has already developed two new silicon negative electrode batteries for its upcoming devices. One is 2770 x 2 = 5540mAh-min, with a typical value of 5700mAh ±, and the other is 2820 x 2 = 5640mAh-min, with a typical value of 5800mAh ±. They mentioned that both of these new batteries support 100W wired charging, have very friendly volume control, and can be used in phones with curved screens.

According to OPPO's product planning, these two large batteries exceeding 5500mAh are likely to be used in the next generation of OnePlus 13 and OPPO Find X8 series. The upcoming GT6 Pro may also adopt this new battery technology. This shift indicates a trend where many manufacturers have been focusing on fast charging speeds, with some reaching up to 300W. However, for consumers, this hasn't brought significant perceptible improvements. Since the second half of last year, smartphone companies have shifted their focus towards larger batteries, continuously increasing battery capacity and density, with charging powers mostly staying below 150W. Compared to the saved ten minutes from fast charging, longer battery life undoubtedly provides a stronger benefit in terms of user experience.
