What is the difference between black gold battery and electric vehicle lithium ion battery?

The differences between lithium-ion batteries and black gold batteries for electric vehicles are as follows: 1. Safety comparison: power-type lithium-ion batteries (lithium manganate, lithium iron phosphate) have different safety materials. Black gold battery technology is quite mature and safer than lithium High ion battery. 2. Environmental protection comparison: Li-ion batteries are not polluted (most of them, but there are also manufacturers that do relatively poorly), while black gold batteries are polluted by heavy metal lead. Therefore, electric vehicles using lead-acid batteries will still pollute the environment. 3. Price comparison: The price of lithium-ion batteries with the same capacity on the market is more than double that of black-gold batteries. This is why electric vehicles using lithium-ion batteries are more expensive. 4. Energy comparison: The mass ratio, volume ratio, and energy ratio of lithium ion batteries are about 40% higher than that of black gold batteries. 5. Comparison of self-discharge rate: The monthly self-discharge of lithium-ion batteries is less than 3%, while that of black-gold batteries is 15-30%. 6. Comparison of service life: The current universal lithium iron phosphate is charged for 1500 times without memory effect. After 1500 times, the storage capacity is about 85%, while the storage capacity of black gold batteries is about 500 times. The storage capacity will be greatly reduced, and the memory effect is very high. distinct. Therefore, the battery life of electric vehicles using lithium-ion batteries will be longer. 7. Voltage platform comparison: Li-ion battery voltage platform is greater than 3V, black gold battery is 2V. 8. Comparison of discharge characteristics: Simply put, when a battery with the same capacity is discharged at a high current, a lithium ion battery discharges about 30% more electricity than a black gold battery.
