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

Green Car Congress

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. That will see an uptake of more hybrid-, plug-in hybrids and BEVs in the EU.

year involvement with NS, which also includes the parallel development of a hybrid system for line-haul locomotives, noted Axion Power Chairman & CEO Thomas Granville. The contract is also a milestone in NS’ quest for a battery/hybrid locomotive, which reaches back a number of years to the Green Goat effort. Micro-hybrids.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Ioxus says that it is working on increasing the energy densities as well. both electrodes are carbon, as opposed to the hybrid (asymmetric) ultracapacitors in which in one of the electrodes is carbon and the other electrode utilizes a different material. Ioxus makes carbon-carbon ultracapacitors—i.e.,
