Patent ID: 10483595

Abstract:
The invention concerns a high-performance tungsten-based super battery system, which relates to an integrated design and a construction method of a corresponding material, a structure and a process. In the technology, a tungsten-based material is used a negative electrode, and a high-specific-surface-area carbon or lead oxide is used as a positive electrode to assemble four types of super batteries comprising: 1) a tungsten-carbon super battery, 2) a tungsten-tungsten super battery, 3) a tungsten-lead oxide super battery, and 4) a super battery system of a hybridized tungsten super battery (comprising lead oxide, lead, and a carbon material) on which the foregoing two types of super batteries are hybridized in use. The introduction of the tungsten-based material endows a novel class of super batteries with higher power density, higher energy density, longer cycling life, high durability and reliable safety. This will enable a broad range of applications.
