Abstract Lithium-ion batteries (LIBs) have become the most important rechargeable battery for portable devices, electric vehicles (EVs) and large scale energy storage systems (ESSs) with high energy density and long cycle life. However, such an increasing demand for LIBs may induce a price increase of Li, Co-containing law materials and anode materials. Here we present a new battery system that is not affected by the price of cathode materials and low cost Pb-based anode materials for post LIBs. First, we introduce a new concept energy storage device that uses natural seawater as a cathode material. Seawater batteries store sodium (Na) ions from the seawater into the anode side during charging and then the harvested Na metal can be discharged with seawater to produce electricity. We discuss the cell design and development of coin-type seawater batteries, and the novel use of TiO2 nanotubes as a photo-anode to increase voltage efficiency. The cell design of seawater batteries and improved voltage efficiencies are mainly discussed. Second, we present Pb-based composite anode materials for sodium-ion batteries (SIBs) and seawater batteries. Lead and lead oxides have advantages of low cost and high volumetric energy density. Here, we report Pb-O-C composite anodes synthesized by simple a high energy ball milling process. The electrochemical data tested in sodium cells show higher reversible capacity and improved cycle stability when compared to previously reported data of lead and lead oxides materials. The reaction mechanism and effect of composite structure are discussed in detail. Studies of this novel solar seawater battery and Pb-based anode materials are in the early stage and further performance improvements are under development. However, we expect they to have global application for low cost ESSs in the near future. 1PDF Image | China solar seawater battery

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
