Solar Batteries
The Basic Facts Of Solar Battery
Solar power is an effective way to harness the power of the sun, the plants have been doing this for millions of years. Solar energy is cheap, reliable and can produce tremendous power, but only in the daytime. This is the main problem of solar energy utilization. The average home will use less power during the day, and much smaller in the summer which is the peak power (fastest time) for solar panels to generate energy. To be effective this power should be stored.
One popular way to store solar power is to connect the solar panels to the electrical grid, which effectively turn it into a battery. This allows excess energy to be sent back to the electric company, actually make the electric meter run backwards. At night, the power drawn from the grid as usual. This is only as reliable as the existing grid. Each power outages could still affect these solar panels, but no rechargeable batteries should be used.
Rechargeable batteries are known for having a short age, and expensive. They also have low power flow for a long time with good capacity, or they have a high power electrical short time with the poor capacity. Typical batteries, especially lithium ion, has a high capacity to store power, but provides a weak output and recharge slowly. An ideal solar battery will be able to charge quickly, has a high density to save power and can emit as much power as needed. This ideal combination is something that no battery has been able to do until now. It can only be done through the study of nanotechnology.
Researchers at the University of Maryland have developed a way to create a very powerful battery, the dense refill using nanotechnology. Individual parts, which looks surprisingly like a photovoltaic panel is only a thousand times smaller, is assembling his own, self-replication, and aligning itself too. There is no mechanical process can achieve anything similar small, which also contributes to their relatively low cost. They are still in the testing stage and court, but should look widely and production operations in a year. Able to store the power created from sun and wind will soon make fossil fuels obsolete and mysterious.
