Hydro battery can generally be used for 2-5 years.
As the battery contains a large amount of liquid, it is generally called a “water battery”. The liquid in the water battery is relatively easy to lose, so it needs to be replenished frequently, so it is also called maintainable battery. This type of battery is mainly used in cars and motorcycles, and its discharge current is relatively large, so it is also called traction battery and starting battery.

There are many things that can produce electricity by adding water. Today's liquid batteries use metals and other active oxides as two electrodes, but I think the following is more interesting The original posterYou can take a look at the "water watch" launched by Japan's Daioh Manufacturing Co., Ltd., priced at 1,980 yen. green watch which can generate electricity after adding water without using dry batteries This product is a green digital watch which does not require dry batteries or external power supply after pouring water into. the water supply tank, it can generate electricity and the liquid crystal part will display the time When the water runs out, the time display will also stop, so it is necessary to. replenish water in time when water is insufficient. Water injection can d.last 2 to 3 months. The metal and activated carbon inside the green watch will react with water and play the same role as a dry battery. The metal part and activated carbon serve as the electrode materials, the negative electrode and the positive electrode respectively, and water becomes the electrolyte to generate current between the electrodes.
Where can 12v120 mAh water battery be used?
(1) Nanomaterials have strong adsorption properties and can increase the adsorption area. This battery uses nanometers of manganese dioxide. The stem is a positive. electrode material which can improve the efficiency of power generation, so the answer is: stronger adsorption capacity (or larger surface area);
(2) Depending on the reaction total battery: 5MnO2+2Ag+2NaCL=Na2Mn5O10 +2AgCl, it is the metallic silver that loses electrons, and the oxidation reaction that loses electrons occurs on the electrodee negative of the original battery. Therefore, the negative electrode reaction is Ag+Cl--e-=AgCl↓. Na2Mn5O10 is generated, 2 moles of metallic silver are consumed and 2 moles of electrons are transferred, so the answer is: Ag+Cl--e-=AgCl↓;2;
(3) According to . the reaction: MnO2+C2O42-+4H+=Mn2++2CO2↑+2H2O, 2MnO4-+5C2O42 -+16H+=2Mn2++10CO2↑+8H2O, the relationship formula is obtained: 5MnO2--5C2O42---2MnO4- , assuming the mass formula n of manganese dioxide, then

Answer: The fraction mass of MnO2 in pyrolusite is 72.5%
Researchers have recently invented a “water” battery that can use the difference in salt content between fresh water and sea water to produce electricity. The battery reacts in sea water.
. Widely used in automobiles, electric vehicles, small cars, power tools, emergency lighting, audio and video products, navigation, electronic toys, testing instruments, etc.
12 V batteries have excellent performance. easy to use and charge, it is therefore favored by consumers, particularly in the automotive field, and is more widely used in electric vehicles.es, 12V batteries are small in size, large in capacity and have a long battery life
Water cells. Purpose: Using single water as raw material, as long as the specified amount of water is injected into the "water battery", it can produce electricity, whether it is tap water, soy sauce, drinks or. sea water, the battery can produce electricity.
Characteristics of water batteries: A water fuel cell of the same size can provide 8 times the electrical energy of a methanol fuel cell, which means that a water fuel cell can be very small to fit the size of a mobile phone. Compared to lithium-ion batteries, water fuel cells take less time to charge. As a result, the capacity is several times larger, so the standby time of the mobile phone can be extended. several weeks or even one or two months, and the conversation time does notcan no longer be calculated in hours
(1) According to the total response of the battery: 5MnO2+2Ag+2NaCl=Na2Mn5O10+2AgCl. . It can be judged that Ag should be the negative electrode of the original battery. The electrode equation for the negative electrode reaction is: Ag+Cl--e-=AgCl, so the answer is: Ag+Cl--e -=. AgCl;
(2) In primary battery, anions move towards negative electrode and cations move towards positive electrode, so sodium ions move towards positive electrode, therefore the answer is: positive;
(3) According to the equation in which 5MnO2 generates 1Na2Mn5O10, the valence is reduced by 2, so for each mole of Na2Mn5O10 generated, 2 moles of electrons are transferred, and when the external circuit lets 4 moles of electrons pass through, the quantity of material which generates Na2Mn5O10 is 2 mol, so the answer is: 2 mol
