"Affordable" rechargeable zinc-key materials for air batteries have been developed -Lithium - Ion Battery Equipment
The reporter learned from Central South University that Professor Lei Yongpeng's team of the school developed a graphene gas gel electrocatalyst that can be used for recharge zinc-air batteries. First, performance is comparable to it. Related results were published in the Energy Express of the American Chemistry Association, an internationally renowned academic journal.
Lei Yongpeng introduced that zinc-air batteries are more "high-end" than batteries such as lithium ions and lithium iron phosphates on the market. Theoretical energy density is 2 times that of lithium batteries and 8 times the lead-acid battery. "The existing lithium ion batteries in the market uses an electrolyte, and the internal is easy to be short-circuited. If it is improperly used, there will be risks such as explosion. Zinc-air batteries use oxygen in the air as positive active substances, and zinc with rich earth reserves as negative polar active substances. With the water solution as an electrolyte, there is no risk of explosion, and the cost of raw materials is much lower than lithium -ion batteries. It is a high -energy density, safety and environmental protection, low cost, zero pollution and renewable battery. "(Lithium - Ion Battery Equipment)
It is reported that a zinc-air battery has been used for electronic devices such as hearing products, navigation lamps and railway signal devices. However, the useful metals such as platinum and 金 as a recipient zinc-air battery, due to the high price of catalysts, affects its consumer electronics products such as mobile phones, laptops, and electric vehicles, electric vehicles, drones and other loading tools. application.
This time, the team has made breakthroughs in the design and battery performance of the catalyst: the oxide graphene and graphite nitride nitride nano -nanol tablets are the main raw materials. Graphene gas gel catalysts are assembled with capable zinc-air batteries. The battery energy density is as high as 872.3WHKGGG-1. After the circulation is 234 times, the performance has no obvious attenuation, showing excellent charging stability.
