Li-ion battery





These portable wind turbines can be packed into the trunk of your car!

While renewable energy resources are indeed the future, many of the currently-available technologies lack feasibility when it comes to widespread, everyday use. For instance, even with the falling price of solar panels, installing a home-based photovoltaic array is often quite an expensive affair. Although the most viable option, in certain areas, wind power usually requires…


Tin-oxide nanoparticles can reduce the charging time of Li-ion batteries from hours to mere minutes

In October, we talked about an advanced Li-ion battery design that replaces graphite with the cheaper titanium dioxide gel. This time around, scientists at the Purdue University have developed a new alternative for graphite, in the form of a material made from tin-oxide nanoparticles. According to their research (which is published in Advanced Energy Materials),…
