Description
Technical Field
The invention relates to a life battery and a preparation method thereof, in particular to a life battery based on a biological discharge principle and a preparation method thereof, and also relates to a device for preparing the life battery, belonging to the technical field of batteries.
Background
It is known that there are some organisms in nature which will discharge, such as eels, rajas, catfishes, etc., wherein the peak voltage of eels during discharge can be as high as 800V, which is the most powerful freshwater fish of the fishes, so it is called "high voltage line" in water. The peculiar biological discharge phenomenon arouses great interest, and at the end of the 18 th century, Galvani finds that the frog muscle contracts when contacting with a loop formed by different metals, and puts forward the view of 'animal electricity' for the first time. Since then, many experiments have demonstrated the existence of "animal electricity", researchers have proposed theories such as "resting potential", "membranous theory", etc., to attempt to explain bioelectrical phenomena, but these theories have not been confirmed, limited by experimental conditions. Until 1939, microelectrodes were inserted into the large nerves of Sepiella maindroni, and the potential difference between the inside and outside of the nerve fiber membrane was directly measured, thus proving the existence of resting potential. This innovation in technology has driven the development of electrophysiological theories.
At present, researchers have made a more thorough understanding of the mechanism of biological discharge. In the case of electric eel, the muscles on both sides of the tail are composed of 6000 to 10000 regularly arranged thin cells, which are separated by connective tissue and have many nerves connected to the central nervous system. The cell membrane of each flake cell has a large amount of Na+/K+Channels, which are under neural control, determine ion migration inside and outside the cell. K in cell membrane of front and back sides under non-irritant condition+All channels are open, K+Migrating from inside to outside to form a 'resting potential' of about-65 mV, but offsetting the front and back, the overall voltage of the cell is zero; in a stressed state, the anterior membrane K+The channel is closed and Na+Opening of the channel, Na+The membrane still retains K after migration from outside to inside and thus forms an "action potential" of about +85mV+The channel is opened unchanged, so the whole battery generates an open-circuit voltage of about 150mV, and thousands of sheets are connected in series to generate a voltage of 300-800V.
Although artificial electronic organs, implantable or wearable electronic devices have been developed in the prior art, most instruments still require a traditional chemical power source (such as a lithium-iodine battery) as a supporting power source, and the development and application of the devices are still restricted by the problems of biocompatibility and service life.
