3. Xiang Fenghua
The company specializes in the research, development, production and sales of anode materials for lithium-ion batteries. It is the leader of anode materials for lithium batteries and the second largest supplier of anode materials for lithium batteries in contemporary Anpu Technology Co., Ltd.. At the same time, for sodium ion batteries, the company has developed high-performance hard carbon anode materials, which have entered the customer testing stage.
The difference between sodium battery and lithium battery
1. The internal charge carriers of batteries are different: lithium-ion batteries are charged and discharged by the movement and conversion of lithium ions between the positive and negative electrodes, while sodium-ion batteries are charged and discharged by the insertion and removal of sodium ions between the positive and negative electrodes. In fact, they work on the same principle.
2. The ionic radii of the two batteries are different: the performance of sodium ion battery is far worse than that of lithium ion battery due to this radius difference; Lithium-ion cathode can make graphite, but sodium ions can hardly intercalate and intercalate in graphite, so the capacity is very small.
3. There is a difference in energy density between sodium battery and lithium battery: energy density refers to the amount of energy that can be stored by a battery with unit volume or mass. Because the sodium ion of sodium battery is relatively large and heavy, the energy density of sodium battery is usually relatively high. This means that under the same volume or weight, sodium batteries can store more energy and provide longer service life.
