What is capacity degradation of Li-ion battery pack? Capacity degradation refers to the phenomenon that Li-ion battery packs gradually lose their usable capacity during use. Li-ion Battery Pack capacity decay is caused by changes in the internal chemistry of the battery. As the battery usage time increases, the positive and negative materials of the battery will undergo structural changes, such as particle aggregation, surface film formation, etc. resulting in a gradual decrease in the usable capacity of the battery. Capacity decay is a normal aging phenomenon of lithium battery Pack, with the increase of use time, the capacity of the battery will gradually decrease. The rate of capacity degradation is affected by a variety of factors, including the number of charge/discharge cycles, charge/discharge rate, charging temperature, storage temperature and so on. In order to prolong the life of Li-ion battery packs, measures can be taken such as avoiding over-charging and discharging, controlling the temperature, and using appropriate chargers to slow down the rate of capacity degradation. #solarenergystorage #solarpower #sustainability #solarenergy #inverter #EVchargingstation #jsdsolar #solarpowersystem #hybridsolar #offgridandongridsolarpowersystem #lithiumbattery #solarsystem #solarenergy #solarpv #solarindustry #solarproject #lithiumionbatteries #lithiumion #lithiumpower #lithium #inverter #inverterbattery #inverters #electronicvehicle #hybridsystem #offgridsolarsystem #ongridsolarsystem #bms

Supercapacitor A type of storage system ·       Have a great power density ·       Have great specific capacitance There are three types of supercapacitors 1.Electrode-electrolyte interface: Electrode double layer capacitors (EDLCs) : High power density but relatively low energy density 2. Pseudocapacitors: Uses redox reactions at the electrode surface Offering higher energy density but often at the expense of lower power density 3.Asymmetric supercapacitors: Utilizing both EDLC and pseudo-capacitors electrode materials within the same device. The positive electrode is typically made of high –surface area carbon material for EDLC-like behavior. While the negative electrode incorporates a pseudo-capacitive material like metal oxides or conducting polymers. ·       High energy density than traditional EDLCs ·       Maintain the rapid charge and discharge rate characteristic of super-capacitor Application: 1.Regenerative braking system for electric vehicles. 2.Peak power leveling in renewable energy systems. 3.Portable electronic devices Conundrum, Research needed to be carried out for ·       High power vs high energy density optimization ·       Suitable material fabrication for electrode ·       Maintaining good cycling stability ·       Maintaining long-term performance  #supercapacitors #hybridsupercapacitors #energystorage #energystoragedevices #materialsscience #materialsengineering #electrochemical #capacitance #greenenergy #greenchemistry
