PPT on Nuclear Microbatteries

Somatic cell nuclear transfer ppt Technology. As the Ni decays it emits beta particles, which are high-energy electrons that spontaneously fly out of the radioisotope’s unstable nucleus. Tech ECE 4th Year. NASA is trying to harness this technology in space applications. Absorbed radiation microbatterids electron-hole pair which in turn results in the generation of electric current. Automobiles No need for frequent recharging as in case of present electric vehicles.

Until final disposal all Radiation Protection Standards must be met. After a brief period — whose length depends on the shape and material of the cantilever and the initial size of the gap- the cantilever come close enough to the source to discharge the accumulated electrons by direct contact. Fuel and Solar cells are expensive and requires sunlight respectively.

Then mail to us immediately to get the full report. These daintiset get collected on the copper sheet. The word ‘dainty’ means pretty. Uses energy from beta particles. Energy Production Mechanism 5. Nuclear pestel ppt 2 Documents. Nuclear Battery uses emissions from radioisotope to generate electricity. The most powerful source of energy known is radium Gamma – These are photons, just like light, except of much higher energy. Others are developing on-chip combustion engines, which actually burn a fuel like gasoline to drive a minuscule electric generator.

These devices use thin radioactive films that pack in energy at densities nucleag of times greater than those of lithium-ion batteries. Depending on the application, these devices often require an on board power source for remote operation, especially in cases requiring for an extended period of time.

Since it is not easy to micro fabricate solid radioactive materials, a liquid source is used instead for the micro machined p-n junction battery. So the scientists had to find some other ways of converting nuclear energy into electric energy. Need for compact, reliable, light weight and long life power supplies.

On this cantilever beam there is a copper sheet attached to it. Reduces green house and associated effectsFuel used is the nuclear waste from nuclear fission. Batteries should have reliability and longevity to avoid frequent replacements.

This concept involves a more direct use of the charged particles produced by the decay of the radio active source: The emitted beta particles ionized the diode’s atoms, exciting unpaired electrons and holes that are separated at the vicinity of the p-n interface. The idea of nuclear battery was introduced in the beginning ofand was patented on March 3rd, to Tracer lab. The device consists of a small quantity of Ni placed near an ordinary silicon p-n junction – a diode, basically.

As shown in figure a number of bulk-etched channels have been Micro machined in this p-n junction. It consists of a core composed of radioactive elements.

nuclear batteries

The following figure shows the experimental setup. Because of the high energy density nuclear batteries are extremely small in size. In the quest to boost micro scale power generation several groups have turn their efforts to well known enable sources, namely hydrogen and hydrocarbon fuels such as propane, methane, gasoline and diesel.

High power for long time independent of atmospheric conditions. Nuclear batteries have lifespan up to decades. Dalntiest process will repeat as long as the source is active.

The diagram of a micro machined p-n junction is shown below.

But all these approaches have some difficulties regarding low energy densities, elimination of by daintieest, down scaling and recharging. Effect of silver co-sputtering on amorphous V2O5 thin-films for microbatteries Documents. They have succeeded by developing nuclear batteries. Batteries of the near future.

Compact and lighter in weight.
