Rechargable battery virus

Now that the researchers have demonstrated they can wire virus batteries at the nanoscale, they intend to pursue even better batteries using materials with higher voltage and capacitance, such as manganese phosphate and nickel phosphate, said Belcher. Once that next generation is ready, the technology could go into commercial production, she said. Lead authors of the Science paper are Yun Jung Lee and Hyunjung Yi, graduate students in materials science and engineering.

In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way. At the Massachusetts Institute of Technology MIT in Cambridge, she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries, the scientists combine what they know about biology the study of living things , technology and production techniques. Professor Angela Belcher shows off the virus-built battery she helped engineer.

The battery — the silver-colored disk on the right side of the device — is being used to power an LED. Many batteries are already pretty small. You can hold A, C and D batteries in your hand and the coin-like batteries that power watches are often smaller than a penny. However, every year, new electronic devices like personal music players or cell phones get smaller than the year before. The ideal battery will store a lot of energy in a small package. But inside, its components are very small—so tiny you can only see them with a powerful microscope.

How small are these battery parts? To get some idea of the size, pluck one hair from your head unless that seems too painful. Place your hair on a piece of white paper and try to see how wide your hair is—pretty thin, right? To humans, the M13 virus is actually harmless.

The virus only infects bacteria. Under a powerful microscope, the M13 virus looks like a thread. A virus usually has two main parts: a shell and genetic material, molecules called nucleic acid, inside the shell.

Not sure where to start? Check Price. Energizer was the first to the market with a line of rechargeable batteries made with recycled materials—4-percent of the components inside are previously used batteries.

These Energizer rechargeable batteries are made of nickel-metal hydride NiMH and are more environmentally friendly batteries that can be charged up to 1, times at up to 2, mAh. While these particular rechargeable batteries do not come pre-charged and ready to use like some others in this round-up do, once they are powered up the charge lasts up to one year in storage and you can also expect up to five years of usable battery life.

Why it made the cut: A reliable choice even if you put a pack in a drawer and forget about it for a long time. You will rarely have to think about replacing these batteries even if you feel like you are a pretty frequent user of gear that requires them. The eneloop batteries are designed to be able to be charged for up to 2, times and can be recharged even if they have only been partially drained of their energy. Another idea to consider is to preload gifts to those loved ones with these batteries, which are charged straight out of the package and ready to use.

Why it made the cut: Hassle-free micro-USB charging port on the battery makes this a serious universal choice. This model can be charged at least 1, times and will last most people for a number of years. A single battery can be charged with any micro-USB cable connected to a powered USB port and the pack comes with a 4-in-1 charging cable LED lights on top of the batteries indicate charging progress. You may want to consider keeping an eye on these so as to be mindful not to overcharge and minimize the chance of having some unwanted outcome.
