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

Green Car Congress

The study, which provides a joint industry analysis of how different types of batteries are used in different automotive applications, concludes that lead-based batteries will by necessity remain the most wide-spread energy storage system in automotive applications for the foreseeable future. In full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.

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. The researchers also concluded that the energy market sector and its use of the lead-acid battery will continue to grow with significant expansion in use for storage in renewable energy systems.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Typical ultracapacitors are characterized by high power density compared to batteries (but poor energy density), as well as quick charge and discharge. Energy densities for the cells are typically around 2-4 Wh/kg. Ioxus says that it is working on increasing the energy densities as well. Energy densities of hybrid ultracapacitors can be significantly greater than that of carbon-carbon ultracapacitors, but power densities are lower.
