When the world focuses on lithium battery cathode materials, white carbon black is quietly becoming the "behind the scenes hero" in improving battery performance. In solid-state electrolytes, nanoscale white carbon black can be used as a filler to construct a three-dimensional ion conduction network, increasing the lithium ion migration number to over 0.8 while inhibiting lithium dendrite growth, resulting in a battery cycle life exceeding 2000 times. Even more surprising is that in the field of hydrogen energy, modified white carbon black as a catalyst carrier can reduce the amount of platinum catalyst by 70%, while increasing the catalytic efficiency by three times, significantly reducing the cost of fuel cells. In addition, the white carbon black based composite also shows excellent anti-aging performance in the photovoltaic adhesive film, which extends the service life of the solar panel to more than 30 years. These breakthrough applications have made white carbon black an indispensable "hidden champion" in the new energy industry chain.
