What are the advantages and disadvantages of lithium batteries and Ni-MH high-rate batteries?

Lithium batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and use non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the production, storage and use of lithium metal have high environmental requirements. Advantages: small self-discharge, no memory effect, small size, light weight, green and environmental protection. Disadvantages: high manufacturing process requirements, high cost, low current, and inability to overcharge. The energy density of lithium batteries is 48% higher than that of nickel-hydrogen batteries. The cycle life can reach more than 600 times of charge and discharge. Since the specifications of lithium batteries are not uniform, there will be cases where the batteries cannot be purchased after production is discontinued. However, it has improved a lot. Ni-MH high-rate battery Ni-MH battery is a kind of battery with good performance. As an important direction of hydrogen energy application, people are paying more and more attention. Advantages: low price, strong versatility, high current, strong reliability, good over-discharge, over-charge protection, high charge-discharge rate resistance, no dendrite formation, excellent low-temperature performance, at -10°C , The capacity has not changed significantly. Disadvantages: large size, relatively heavy, and short cycle life. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
