FAQ
Battery Types and Applications
What is a paper battery? What is a smart secondary battery?
Why do fuel cells have great development potential?
1) High efficiency. Because the chemical energy of the fuel is directly converted into electrical energy without thermal energy conversion in the middle, the conversion efficiency is not limited by the thermodynamic Carnot cycle; because there is no conversion of mechanical energy, mechanical transmission losses can be avoided, and the conversion efficiency does not depend on the size of the power generation. And change, so the fuel cell has higher conversion efficiency;
2) Low noise and low pollution. In the process of converting chemical energy into electrical energy, the fuel cell has no mechanical moving parts, but the control system has some small moving parts, so it is low-noise. In addition, fuel cells are low-pollution energy sources. Taking phosphoric acid fuel cells as an example, the sulfur oxides and nitrogen compounds they emit are two orders of magnitude lower than the U.S. regulations;
3) Strong adaptability. Fuel cells can use various hydrogen-containing fuels, such as methane, methanol, ethanol, biogas, petroleum gas, natural gas and synthetic gas, etc. The oxidant is inexhaustible air. Fuel cells can be made into standard components with a certain power (such as 40 kilowatts), assembled into different powers and types according to the user's needs, and installed in the most convenient place for the user. If necessary, it can also be installed into a large power station and used in connection with the conventional power supply system, which will help regulate the power load;
4) Short construction period and easy maintenance. After the industrial production of fuel cells is established, various standard components of power generation devices can be continuously produced in factories. It is easy to transport and can be assembled on-site at the power station. Some people estimate that the maintenance required for a 40-kilowatt phosphoric acid fuel cell is only 25% of that of a diesel generator of the same power.
Because fuel cells have so many advantages, both the United States and Japan attach great importance to its development.
Battery Performance and Testing
What is the standard charge retention test?
After the battery is discharged to 1.0V at 0.2C, it is charged at 0.1C for 16 hours, stored at a temperature of 20℃±5℃ and a humidity of 65%±20% for 28 days, and then discharged to 1.0V at 0.2C. NiMH batteries should last longer than 3 hours.
The national standard stipulates that the standard charge retention test of lithium batteries is: (IEC has no relevant standards) The battery is discharged to 3.0/unit at 0.2C, and then charged to 4.2V at 1C constant current and constant voltage, with a cut-off current of 10mA, at a temperature of 20 ℃±5℃, after 28 days of storage, discharge at 0.2C to 2.75V, calculate the discharge capacity, and compare it with the battery's nominal capacity, it should not be less than 85% of the initial capacity.
What is the power output of the battery?
The smaller the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be smaller than the internal resistance of the electrical appliance. Otherwise, the power consumed by the battery itself will be greater than the power consumed by the electrical appliance, which is uneconomical and may damage the battery.
Battery and Analysis
What is overcharging and what effect does it have on battery performance?
Positive electrode: 4OH- - 4e → 2H2O + O2↑;①
Negative electrode: 2H2 + O2 → 2H2O②
Since the negative electrode capacity is higher than the positive electrode capacity during design, the oxygen generated by the positive electrode passes through the separator paper and combines with the hydrogen generated by the negative electrode. Therefore, under normal circumstances, the internal pressure of the battery will not increase significantly. However, if the charging current is too large, Or if the charging time is too long, the generated oxygen will not be consumed in time, which may cause the internal pressure to rise, battery deformation, leakage and other adverse phenomena. At the same time, its electrical properties will also be significantly reduced.
