New energy

Graphite materials hold paramount significance within the realm of new energy technologies. In the domain of lithium-ion batteries, graphite is widely recognized as a conventional negative electrode material.

Take artificial graphite as an illustrative case; it is synthesized via high-temperature graphitization processing of raw materials such as petroleum coke. This material exhibits a suite of advantageous properties, including a low-potential plateau, high specific capacity, excellent cycling stability, and cost-effectiveness.

During the charge-discharge cycles of lithium-ion batteries, lithium ions undergo intercalation into and deintercalation from the positive and negative electrodes. The layered architecture of graphite offers an extensive storage matrix for lithium ions, thereby guaranteeing high energy density and consistent charge-discharge performance in the battery. It stands as a pivotal determinant influencing both the initial coulombic efficiency and the cycle longevity of lithium-ion batteries.

In the context of fuel cells, graphite also finds pertinent applications. It can be employed to manufacture electrode materials for fuel cells. By capitalizing on its superior electrical conductivity and remarkable chemical inertness, graphite accelerates electrochemical reactions, consequently enhancing the power generation efficiency of fuel cells.

Furthermore, in the ongoing research and development endeavors of emerging energy storage devices, the distinctive physicochemical attributes of graphite materials pave the way for exploring high-performance energy storage modalities, thus playing a crucial role in propelling the advancement of the new energy industry.
