On environmental issues: lithium-ion batteries are greener. However, lead-acid batteries have been used for 150 years and environmental problems have always existed, but they have always been used. Of course, many restrictions have begun to appear in recent years. Lead carbon batteries, essentially a new type of lead-acid battery, have environmental problems with lead. Environmental pollution is about 100 %, and the total pollution of lead-acid batteries(lead smoke, lead dust, acid mist and waste water) accounts for about 1 %, which is not small, and local areas are far greater than this assessment.
On the issue of cycle life: Of course, lithium batteries have a longer life, and lead-acid batteries have a shorter life. Therefore, lithium batteries are more expensive to buy and cheaper to use, which is due to the long life.
Self-discharge rate: The self-discharge rate of lithium batteries is much smaller than that of lead-acid batteries, which can not be compared with lead-acid batteries.
Type self-discharge rate/month
Alkaline manganese MnO2 / Zn circular battery "2 %
Zinc carbon MnO2 / Zn circular battery "4 %
Lithium-ion lithium MnO2 circular battery about 1 %
Lithium-ion lithium MnO2 button battery about 1 %
Nickel-cadmium battery 35 %
Nickel hydride battery "35 %
Lead acid batteries 20-30 %
Voltage platform: lead-acid battery is 2V, lithium battery is 3.2 V to 4.8 V according to different varieties.
Application maturity: Although my lead-acid battery application has a long history, can be said to be grandfather level. But lithium-ion batteries are now much more widely used than lead-carbon batteries.
Commodity price: Since lead-carbon batteries have not yet been used on a large scale, the current manufacturing cost is much higher than that of lead-acid batteries, but it will be lower if manufactured in large quantities. In terms of the comprehensive cost of application, the difference in the combined cost of the two batteries is not very different, and lithium ion batteries are more economical.
One-time investment: At present, one-time investment expenses, lead-carbon batteries have advantages, such as for electric bicycles, so that the car's price is lower than that of lithium batteries. Given their life span, lead-carbon batteries do not have much advantage.
In short, the two types of batteries may have different fields that can coexist for a long period of time, give play to their respective market advantages, and there will be no incompatible situation. There is no relationship between lead-carbon batteries and lithium-ion batteries.
