Second rechargeable battery: thanks to the reversibility of chemical reactions, a new battery can be formed. That is, once a chemical reaction is converted into electrical energy, the electrical energy can be used to repair the chemical system and then the chemical. The reaction can be used to convert into electrical energy, which is why it is called secondary battery (rechargeable battery). Rechargeable Battery: Rechargeable battery, also called rechargeable battery or storage battery, refers to a battery that can be activated by charging to continue using the active material after the battery is discharged.
Rechargeable batteries can charge and discharge cycles from thousands to tens of thousands of times, so they are more economical and practical than dry batteries.
The main rechargeable batteries currently on the market include the “nickel-metal hydride”, “nickel-cadmium”, “lead-acid (lead-acid battery)”, “lithium-ion (including lithium batteries and lithium-ion polymer batteries). batteries)", etc.
Self-discharge of secondary batteries is also called charge retention capacity. It refers to the ability to maintain the energy stored in the battery under certain environmental conditions in open circuit Generally speaking, self-discharge is mainly affected by the manufacturing process, materials and storage conditions. Self-discharge is one of the main parameters to measure battery performance. Generally, the lower the battery storage temperature, the lower the self-discharge rate. However, it should also be noted that the temperature is too low or too high, which may damage the battery and make it unusable. require a temperature rangeStorage temperature -20 to 45°C. Once the battery is fully charged and left open for a period of time, some degree of self-discharge is normal. The IEC standard states that after nickel-cadmium and nickel-metal hydride batteries are fully charged and left in open circuit for 28 days at a temperature of 20 degrees and humidity of 65% [1], the discharge time at 0.2°C is longer. respectively more than 3 hours and 3 hours and 15 minutes.
Compared to other rechargeable battery systems, the self-discharge rate of solar cells containing liquid electrolyte is significantly lower, approximately 10%/month at 25°C.
