Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Use the following reaction: Li+MnO2=LiMnO2 This reaction is a redox, discharge reaction. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements.
Solar cells are made of monocrystalline silicon, polycrystalline silicon, thin-film semiconductors and other materials by diffusion to form a PN junction. The PN junction directly converts light energy into electrical energy through the photoelectric effect or photochemical effect.
A silver oxide battery is an alkaline battery that uses silver oxide as the positive active material and zinc as the negative active material. The batteriessilver oxide generally use an aqueous solution of potassium hydroxide as the electrolyte. The reaction of the battery is:
During discharge: Zn+AgO+H2O→Zn(OH)2+Ag
or<. /p>
Zn+Ag2O+H2O→ Zn(OH)2+Ag
When charging: Zn(OH)2+Ag→Zn+AgO+H2O
or
Zn(OH)2+Ag→Zn+Ag2O+H2O
A fuel cell is an electricity production device that directly converts the chemical energy present in fuel and oxidizer into electrical energy. It directly converts the chemical energy of the fuel into electrical energy without going through the combustion process.
