3、 Components of lithium-ion batteries
1. Dry battery (commonly used type is carbon zinc dry battery): The negative electrode is a cylinder made of zinc, with ammonium chloride as the electrolyte, a small amount of zinc chloride, inert filler, and water mixed into a paste electrolyte. The positive electrode is a carbon rod wrapped around a paste electrolyte mixed with manganese dioxide. The electrode reaction is: the zinc atom at the negative electrode becomes a zinc ion (Zn++), releasing electrons, and the ammonium ion (NH4+) at the positive electrode obtains electrons, forming ammonia and hydrogen gas. Using manganese dioxide to remove hydrogen gas to eliminate polarization. The electromotive force is approximately 1.5 volts.
2. Lead acid batteries are the most commonly used, with grids made of lead alloy as the electrode plates and dilute sulfuric acid as the electrolyte. Both polar plates are covered with lead sulfate. But after charging, the lead sulfate on the positive electrode plate is converted into lead dioxide, and the lead sulfate on the negative electrode is converted into metallic lead. When discharging, a chemical reaction occurs in the opposite direction.
3. Lead crystal batteries: Lead crystal batteries use proprietary technology, and the high conductivity silicate electrolyte used is a complex modification of traditional lead-acid battery electrolytes. The acid fog free internalization process is an innovation in the finalization process.
4. Iron nickel battery: also known as Edison battery. Lead acid batteries are a type of acidic battery, unlike iron nickel batteries where the electrolyte is an alkaline potassium hydroxide solution, which is an alkaline battery. Its positive electrode is nickel oxide, and its negative electrode is iron. The electromotive force is approximately 1.3-1.4 volts. Its advantages are lightweight, long lifespan, and easy maintenance, while its disadvantage is low efficiency.
5. Nickel cadmium battery: The positive electrode is nickel hydroxide, the negative electrode is cadmium, and the electrolyte is potassium hydroxide solution.
6. Silver zinc battery: The positive electrode is silver oxide, the negative electrode is zinc, and the electrolyte is potassium hydroxide solution.
7. Fuel cell: A fuel cell consists of four parts: fuel (such as hydrogen, methane, etc.), oxidants (such as oxygen and air, etc.), electrodes, and electrolyte.
8. Solar cell: A device that converts the energy of sunlight into electrical energy.
9. Atomic battery: a device that directly converts nuclear energy into electrical energy (the current nuclear power generation device uses nuclear fission energy to heat steam to drive generators to generate electricity, but it cannot directly convert nuclear energy released during nuclear fission into electrical energy).
10. Alkaline batteries: Alkaline batteries are the most successful high-capacity dry batteries and are currently one of the most cost-effective batteries. Alkaline batteries use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte.
11. Lithium battery: A battery with lithium as the negative electrode. According to the different electrolytes used, they are divided into: ① high-temperature molten salt lithium batteries; ② Organic electrolyte lithium battery; ③ Inorganic non-aqueous electrolyte lithium batteries; ④ Solid lithium battery
Electrolyte lithium battery; ⑤ Lithium water battery. The advantages of lithium batteries are high single cell voltage, high specific energy, long storage life (up to 10 years), good high and low temperature performance, and can be used at -40~150 ℃.
