Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

The advantages of a lithium-ion SLI battery would primarily be in terms of its longer cycle-life and weight reduction when it is considered as a ‘drop-in’ replacement option for the existing lead-acid battery, which has dominated the SLI application market for the last 100 years. This energy sector is primarily driven by the need for low-cost with reasonably long cycle-life energy storage technology, for which the lead-acid battery is well suited.

These issues can lead to low active materials utilization, low coulombic efficiency, and short cycle life of the S electrode.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Advanced lead-based batteries (AGM and EFB technologies) are installed to meet extra requirements in start-stop and basic- micro-hybrid vehicles, due to their increased charge recoverability and higher deep-cycle resistance. Therefore their cycle life, power density and charge acceptance will need to be further improved. Power density, cycle life, energy density and reliability are all expected to be improved by 2025, with overall cost to decrease significantly.

Apparently the alarm is indicating a timeout that the charge cycle is taking too long for the capacity of batteries that I have. After contacting Zivan tech support, they said that lead-acid batteries typically get 400 deep cycles or 800 half-cycles at best. If my average trip is 20 miles between charges and I have 8600 miles on the car, that means about 430 half-cycles. I think my battery pack is dead after 8600 miles and 1.5 years.

For example, they note, to regulate frequency, the energy storage capacity may not need to be long-lasting—minutes can be sufficient—but it must have a long cycle life because the system is likely to encounter multiple daily discharge events. This type of application requires high round-trip energy efficiency and a long deep-cycle life, along with low operation and maintenance costs. Among the most important factors are capital cost and life-cycle cost.
