What is the difference in performance between lithium-ion batteries and nickel hydrogen batteries?
1. Energy density: The energy density of lithium-ion batteries is usually higher than that of nickel hydrogen batteries, which means that lithium-ion batteries can store more energy in the same volume. The energy density of lithium-ion batteries is approximately three times that of nickel hydrogen batteries.
2. Self discharge rate: The self discharge rate of nickel hydrogen batteries is relatively high, which means they will lose power faster when not in use. In contrast, the self discharge rate of lithium-ion batteries is very low, almost negligible.
3. Memory effect: Nickel hydrogen batteries have a memory effect, and if they are not regularly discharged deeply, their capacity may gradually decrease. Lithium ion batteries have no memory effect and can be charged at any time without affecting their performance.
4. Voltage platform: The voltage of a single lithium-ion battery is usually 3.6V, while the voltage of a single nickel hydrogen battery is 1.2V. The high voltage platform of lithium-ion batteries means that they can provide higher voltage output at the same level of charge.
5. Charge and discharge characteristics: Lithium ion batteries typically use constant current constant voltage charging, while nickel hydrogen batteries typically use constant current charging. The charging speed of lithium-ion batteries is usually faster than that of nickel hydrogen batteries.
6. Cycle life: The cycle life of lithium-ion batteries is usually longer than that of nickel hydrogen batteries, which means they can withstand more charge and discharge cycles.
7. Safety: Lithium ion batteries may pose safety risks in the event of overcharging or overdischarging, such as thermal runaway or battery expansion. Nickel hydrogen batteries are relatively safer, but still require proper charging and usage management.
