三星的石墨烯電池是什麼？

一夜之間，鋪天蓋地的微信文章。就沒有人花幾分鐘的時間看看原文么？

只看下摘要：

Improving one property without sacrificing others is challenging for lithium-ion batteries due to the trade-off nature among key parameters. Here we report a chemical vapor deposition process to grow a graphene–silica assembly, called a graphene ball.

CVD方式製備石墨烯-氧化硅複合材料-graphene ball

Its hierarchical three-dimensional structure with the silicon oxide nanoparticle center allows even 1 wt% graphene ball to be uniformly coated onto a nickel-rich layered cathode via scalable Nobilta milling.

這一塊說石墨烯包覆NCM

The graphene-ball coating improves cycle life and fast charging capability by suppressing detrimental side reactions and providing efficient conductive pathways. The graphene ball itself also serves as an anode material with a high specific capacity of 716.2 mAh g?1. A full-cell incorporating graphene balls increases the volumetric energy density by 27.6% compared to a control cell without graphene balls, showing the possibility of achieving 800 Wh L?1 in a commercial cell setting, along with a high cyclability of 78.6% capacity retention after 500 cycles at 5C and 60 °C.

思路是對的。但是CVD要多少錢？能否商業化？這個專利權利要求範圍是不是沒邊了？

石墨烯導電網路和硅材料-做石墨烯的人估計天天想這麼干，無他，給石墨烯找個好出路。

言歸正傳：這哪裡是石墨烯電池！好不

國內的微信號們轉發文章前仔細看看是誰發的？原文說什麼？
