There are a range of technologies available for energy storage, each having a number of tradeoffs in terms of capacity, weight and performance. Capacitors are quick to charge and lightweight, but do not have a large capacity. Batteries are capable of retaining more charge, but are heavy and take a long time to recharge. Graphene is currently known as the best conductive material. The electron mobility of graphene exceeds 15000 cm2/(V·s) at room temperature. Its resistivity is only about 10-6 Ω·cm, which is the smallest resistivity material in the world. Because of these excellent properties, graphene has the potential to produce high-performance batteries, supercapacitors and other fields.
The excellent properties of graphene make it suitable for battery production. Based on the application requirements of graphene in batteries, Alfa Chemistry solves the problems faced by graphene in batteries for different battery systems.
Graphene-based silicon-carbon composites have shown great potential as anode materials for lithium-ion batteries due to their high capacity, good operating potential, environmental friendliness and high abundance. Alfa Chemistry can quickly compound graphene for different silicon materials to solve corresponding problems.
Activated Carbons have received extensive attention in gas storage, catalyst supports and electrode materials due to their high surface area, good electrical conductivity, low cost and easy preparation. We can produce high-surface-area activated carbon to be used for lithium battery supercapacitor electrodes and silicon carbon negative electrodes.
Alfa Chemistry provides comprehensive services to meet customers' research needs for battery and energy storage.
Alfa Chemistry' technical R&D team has focused on the preparation and application of graphene for many years, especially the application of graphene materials in the energy field. We have conducted research on various problems encountered by lithium batteries and designed effective solutions.
