Nickel-cadmium batteries (nickel-cadmium battery) PCGA-BP4V metal cadmium as negative electrode active material, nickel hydroxide positive electrode active material for alkaline batteries. Positive and negative electrode materials were filled in perforated strip attached to nickel (or nickel belt), the by slurry, rolling, sintering, chemical or pasted, drying, tabletting methods such as plate made; polyamide non-woven materials such as an isolation layer; with potassium hydroxide aqueous solution as electrolyte solution; electrode assembly through the coiling or laminated in plastic or nickel-plated steel inside. PCGA-BP2V Ni-Cd battery nominal voltage of 1.2V, a cylindrical enclosure (KR), button (KB), a square enclosed (KC) and many other types. Has a wide temperature range, long life cycle and storage, capable of higher current discharge characteristics, but there is "memory" effect, often a result of regularity caused by the improper use of electrical performance. Ni-Cd batteries battery expression: (-) Cd ︱ KOH (NaOH) ︱ NiOOH (+) Cell reaction is: Discharge: Cd + NiOOH + H2O → Ni (OH) 2 + Cd (OH) 2 Charging time: Ni (OH) 2 + Cd (OH) 2 → Cd + NiOOH + H2O A large bag, and open-type nickel-cadmium batteries used in railway locomotives, mines, armored vehicles, aircraft engines, etc. to start or emergency PCGA-BP2T power supply. Cylindrical sealed nickel-cadmium batteries for electric tools, portable electric shaving devices. Small button nickel-cadmium batteries are used in low current, low-discharge rate of the cordless phones, electric toys. As the nickel-cadmium battery waste pollution of the environment, the series of batteries will be gradually better performance nickel-metal hydride batteries replaced. Lithium battery lithium primary battery Of a high-energy chemical battery. Commonly known as Li-ion battery. With lithium as the anode, solid salts, or soluble in organic solvents for electrolyte salts, metal oxides or other solid, liquid oxidant for the cathode active material. General circular lithium manganese dioxide (Li/MnO2) batteries and lithium fluoride carbon 〔Li / (CFx) n〕 battery CR and BR, respectively, said the letter, the subsequent numbers indicate the battery model. Lithium battery is 60 years since the late 20th century, the development of new chemical PCGA-BP2S power supply.
