What are the advantages and disadvantages of lithium batteries and NiMH 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. Application fields: transportation power supply, electric energy storage power supply, mobile communication power supply, new energy storage power supply, aerospace military power supply, electric vehicle application. 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. In recent years, more and more digital cameras use nickel-metal hydride batteries. Battery manufacturers are also optimistic about this market. They have launched high-capacity nickel-metal hydride rechargeable batteries. The batteries are on par, and even the charger is getting better and better, and the charging time is greatly reduced.
