Comparative analysis of the advantages and disadvantages of fuel power batteries and lithium batteries

The advantages and disadvantages of fuel power batteries and lithium batteries were asked on the Internet: Compared with lithium batteries, what are the advantages and disadvantages of fuel power batteries? The following are answers from battery practitioners. Regarding the comparative advantages and disadvantages, the premise is under the premise of the same purpose of use. First, compare the differences and similarities between the fuel power battery and the lithium battery, and then make use of the different comparative advantages and disadvantages. Different working methods: fuel power battery inputs chemical energy and outputs electrical energy; lithium battery inputs electrical energy and outputs electrical energy. Therefore, the fuel power battery is an energy conversion device, and the lithium battery is an energy storage device. The discharge principle is the same: the energy output of fuel power batteries and lithium batteries is not a thermal process, but an isothermal and adiabatic electrochemical power supply process, so the power is higher. Advantage 1. When the gap is human society on the earth, regarding the significance of future power structure adjustment, fuel power batteryu003e: Most fossils of lithium batteries can represent power share in 1,200 years, how can we progress from fossil energy consumption terminals Useful work, and how to prevent specific useful work methods and confirm that it corresponds to a dynamic structure, the key is the innovative steam engine of energy conversion equipment (people simply analogize the meaning of the industrial revolution), and the use of energy storage devices is often to optimize electrical energy Energy use. 2. When the gap is a car, especially a car on the ground, a fuel-powered battery-powered car is more likely to be similar to today’s automotive industry, rather than a lithium battery-powered car: energy recovery is less than 3 minutes, driving distance More than 400 kilometers. The chemical reaction requires oxidant, reductant (commonly known as fuel) and reaction site. Fuel-powered vehicles only need to carry two: fuel and reaction site fuel-powered batteries; lithium battery vehicles will take all three samples, and lithium battery oxidizers and reductants, The inspection is very close (currently dependent on a few hundred microns thick film). If it does not work, there will be self-discharge. The lithium battery reaches a complete cycle and often imitates a pale, unlike a traditional car, the oil is dried and refueled every cycle. , So when using the binary theory of driving range. This is why the current fuel-powered battery vehicle has a cruising range of more than 600 kilometers, while the lithium-ion vehicle has a cruising range of less than 100 kilometers. Fuel-powered battery vehicles are similar to natural gas internal combustion engine vehicles. The reaction and fuel are physically separated. The actual fuel is a physical process, and the speed can be very fast. It just feels that it is economical, and the energy recovery of lithium battery vehicles is a charging process, that is, electrolysis reaction, management Or attack, we will have a technological advancement that reacts to the fuel filling speed limit. Lack 1. When the gap is a portable electronic device, due to the separation of oxidizer, reductant and echo site, the system integration difficulty of fuel power battery is much greater than that of lithium batteries or other types of secondary batteries that have been fully integrated; 2. When When the gap is an uninterrupted backup of the power grid, it is almost impossible for 2ns electronic equipment to require fuel power cells to send the separated oxidizer and reducing agent to the battery; degree of industrialization: manufacturing of fuel-free power battery products; lithium batteries for portable electronic devices It is now part of the mass manufacturing industry. But as far as automobiles are concerned, neither of them constitutes a product manufacturing industry. The common technical difficulty lies in how to adapt the electrochemical response to the large dynamic demand of the reasonable load of the motor. Simply put, it is confusing: Now that the lithium battery industry has a firm foothold, it is easier for lithium battery vehicles to replace internal combustion engines than fuel-powered battery vehicles. Error in principle: product development starts from customer needs, lawn mowers and internal combustion engines that have not been heard can be upgraded and modified to achieve internal combustion cars; relevant experience: battery cars, since 1900, lithium batteries have entered the first The four waves seem unlikely to succeed in this decade. This is an arduous task. The most promising statement: a fuel-powered battery engine + lithium battery constitutes an electric hybrid vehicle, which can 1) increase twice the power; 2) zero emission of vehicles; 3) the simple arrival of life and capital; 4) Get rid of the single dependence of automobiles on crude oil resources.
