Have you ever wondered battery will eventually go from here? If proper recycling, battery materials can be reused, but if it is thrown into landfills or nature, it will cause irreparable environmental damage. The American scientists have developed a cheap disposable product. Microbial cells not only more environmentally friendly, but also contribute to the development of a one-time system of things.
According to Associate Professor of Electrical and Computer Engineering at Binghamton University Seokheun Choi to say, these new technologies may be equipped with cheap, small, delicate disposable packaging, can only surf or transmit information over a period of time on the Internet.
However, this design is very convenient, but it also means these sensors, circuits, etc. are disposable batteries. If not recycled or environmentally friendly technology, it will bring a huge burden on the environment. Choi team has started the development and use of environmentally friendly and useful disposable batteries.
In the last experiment, the Binghamton University team has two main directions, a one-time low-power paper bio-battery, the other is a long-life microbial fuel cell, but no matter what kind of solutions, both in the experimental research team in, Choi developed microbial fuel cell having a high energy density and low power fluid system. Therefore, the team began to think that low-power, solid-state one-time microbial cells is the most appropriate and most easily implemented. of.
The team finally decided these two solutions combined, and the development of a new generation of one-time microbial cells. According to this FUN88 Public team paper "Journal of Power Sources", bio-anode microbial nutrient storage battery and an ion path μL cell stage. Avoid the use of fluid energy-intensive systems, and significantly extend battery life.
The team also innovatively old anolyte liquid, salt bridge and a cathode compartment into a solid counterparts, to further increase the density of bacteria and slowly and continuously reacted. In addition, by solid phase member, scientists also possible to manufacture smaller, and easier to integrate the battery applications.
According to the experimental groups, the maximum power of the current cell is a microorganism per square centimeter 4μW, a current density of 45μA per square centimeter, and can run for 96 hours as compared to the liquid prior to the control element only the power generation cell for 4 hours.
The argument Choi, most waste things use of expensive and environmentally unfriendly battery. Large-scale application could lead to costly and hard to ignore environmental problems. The team developed a microbial cell is relatively cheap and environmentally friendly. Microbial cells and DC / DC converter integrated.
