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.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. EES has been considered as a key enabler of the smart grid or future grid, which is expected to integrate a significant amount of renewable energy resources while providing fuel (i.e., Click to enlarge.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

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. Energy densities of hybrid ultracapacitors can be significantly greater than that of carbon-carbon ultracapacitors, but power densities are lower.
