We report the preparation of MOS2 anode and solid electrolyte PVDF for the construction of three-dimensional (3D) Li-ion microbatteries based on silicon MCP. The MoS2 layer anode electrode on the Ni layer exhibits a higher specific capacity compared to other anode materials. The outstanding electrochemical property of the MOS2 layer makes it promising anode materials. The PVDF as the electrolyte matrix...
This effort focuses on nanofabricated devices that can be employed to probe the electrochemical behavior of individual nanowires (NWs) as lithium-ion battery electrodes. The hybrid fabrication approach involves synergistic integration of bottom-up (dielectrophoresis) and top-down (silicon nanomachining) manufacturing processes. The structure lends itself to characterizing the electrical and structural...
While advanced batteries have enabled great improvements in society's mobility and energy efficiency, the high cost of batteries hampers further market penetration. Battery technology improvements are most often sought in electrochemical laboratories. But control engineers have an important role to play in advancing this technology. As a first step, the battery community must begin to merge the knowledge...
Microfabrication of on-chip solid state electrochemical cells has provided a robust challenge to industry for the past decade. Previous efforts include RF Sputtering, screen-printing, and laser printing. All have merit in the laboratory but have proven difficult to scale due a combination of equipment cost and proper isolation from water and oxygen. We present a promising method for printing additively...
In this paper, the authors review the up-to-date development of lithium-ion batteries (LIBs), focusing mainly on the situation in Japan. The materials, constructions, and electrochemical performance of the latest commercially available LIBs, including lithium polymer batteries, which have come onto the market only fairly recently, are described in the first half of this article. The authors then discuss...
This paper traces the Bell System's 50 year adventure with the problems and solutions resulting from each new standby battery technology introduced into widespread system use. It describes the change in 1950, from almost 50 years of lead antimony (PbSb) usage to lead calcium (PbCa) technology. The next 12 years resulted in traumatic voltage irregularities, capacity failures, jar cracking and breakage,...
