Battery Performance of Microfiber/Nanofiber Lithium Ion Battery Separators
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high "dead space" that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow.
Smart Cities: Intelligent Transportation and Smart Grid Standards - Part 1
Standards-based solutions were instrumental in the exponential growth of the Internet. For the Smart City, public electrical infrastructure ecosystem to expand, development, application and worker training of interoperability standards is an important strategic foundation from which to grow. This convergence of intelligent transportation systems with the Smart Grid, is allowing the Smart City concept to gain hold in many areas of the US and around the world.
Investing in Solar Energy Industries in the US
As the technology of renewables advances, and as their track records continue to show stable returns, pension funds will continue to increase their investment in renewables, either through direct investment, infrastructure funds or private equity funds.
Advanced Biogas Thermal Mass Flow Meter Boosts Methane Recovery System Operation
The S.P.M. Mill operators initially tried using Oscillator and Vortex technology flow meters. They found that these flow technologies contain moving parts or orifices and were unable to measure flows accurately at the low flow rate demanded by this digester application.
Residential Solar adds to Property Value
On average, a California solar system will pay for itself within five to 10 years, depending on the size of the system. However, if the system is leased and homeowners put little down upfront, the solar system will begin paying for itself on day one, creating instant savings.
Creating a new eCommerce B2B Global Solar and Renewable Energy Marketplace
The iSolar Exchange online marketplace is designed to create a secure site that connects the entire supply, manufacture, and delivery channels for solar and renewable energy products and services - worldwide. That's all we do - that's all we focus on.
3D Solar Technology Improves Efficiency
In current technology about 30% of the light is reflected back into space. We have created a 3-dimentional structure in the silicon that virtually eliminates reflection by causing the light to bounce around within the structure until it is fully absorbed.
