  • Patent number: 10734695
    Abstract: The present disclosure relates to a lithium air battery and a manufacturing method thereof. A seed layer for inducing the growth of thin-film type discharge products is formed on a carbon positive electrode. The number of reaction regions that can react with lithium ions is increased, whereby high-speed discharging is possible. Since the seed layer induces the growth of the thin-film type discharge products, high-speed charging is also possible. In addition, since the seed layer induces the growth of the thin-film type discharge products, it is possible to increase the capacity of the battery. Furthermore, the occurrence of overvoltage in the lithium air battery is reduced, whereby the lifespan of the battery is increased while the stability of the battery is improved.
