Bio-battery
Bio-battery.pptx (Size: 160.93 KB / Downloads: 33) What is Bio-battery A bio-battery is an energy storing device that is powered by organic compounds, usually being glucose, such as the glucose in human blood. When enzymes in our bodies break down glucose, several electrons and protons are released. Therefore, by using enzymes to break down glucose, bio-batteries directly receive energy from glucose. These batteries then store this energy for later use.This concept is almost identical to how both plants and many animals obtain energy How It Works ? Structure Bio-batteries contain an anode, cathode, separator and electrolyte. Each component is layered on top of another component. The anode is located at the top of the battery and the cathode is located at the bottom of the battery. Anodes are components that allow electrons to flow in from outside the battery, whereas cathodes are devices that allow current to flow out from the battery. Between the anode and the cathode lies the electrolyte which contains a separator. This system as a whole, allows for a flow of protons (H+) and electrons (e-) which ultimately generate electricity. Glucose Bio batteries are heavily based on the amount of glucose available. The decomposition of materials to glucose is the main step in getting the cycle started. Materials can be converted into glucose through the process of enzymatic hydrolysis. Enzymatic hydrolysis is the process in which cellulose (an insoluble substance) is converted to glucose with the addition of enzymes.After glucose exists oxygen and other enzymes can act on the glucose to further produce hydrogen ions and electrons. Sony Develops A Bio Battery Powered By Sugar Sony has developed a biologically friendly battery that generates electricity from sugar in a way that's similar to what's found in living organisms. Battery test cells have generated up to 50 milliwatts, or enough electricity to power music playback on a memory-type Walkman. Sony said that the output is the highest for a bio battery of this type. Advantages A significant advantage that bio-batteries have in comparison to other batteries is their ability to allow an instant recharge. In other words through a constant supply of sugar, or glucose, bio batteries are able to continuously keep themselves charged without an external power supply. Bio batteries are also a source of non-flammable, and non-toxic fuel. This provides a clean alternative renewable power source. Disadvantages Compared to conventional batteries, such as lithium batteries, bio-batteries are less likely to retain most of their energy. This causes a problem when it comes to long term usage and storage of energy for these batteries. However, researchers are continuing to develop the battery in order to make it a more practical replacement for current batteries and sources of energy. |
