Navitas Systems receives $1.55M contract for 2nd-gen 6T Li-ion battery; double energy density, +50% power density

Green Car Congress

Navitas Systems will leverage the award to enhance the capabilities of its current Ultanium Military 6T Battery by significantly increasing the energy and power density over the current first generation lithium version. The 12V version can be used in either military or in commercial starting/deep cycle applications.

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

Green Car Congress

In a paper in the Journal of Power Sources , they suggest that the replacement will probably be specific to certain vehicle OEMs and geographical locations. There will still be a need for a 12 V battery for the supply of auxiliary power that will not necessarily be a Pb-acid SLI battery. —Ferg et al. Schuldt, J. 2019.03.063.

Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

The Climate Foundation , the Seattle-based company behind the project, has found that this deep cycling makes kelp grow three times as fast as it can when kept in shallow waters, as seaweed farmers do now. It’s our hope in 2024 to validate our model and then, as [they] say in Silicon Valley, design it once and build it a million times.”

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. That makes a very powerful combination. The electrode can be continuously deep cycled up to 5,000 times without significant capacity decay.

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

EES is already an established, valuable approach for improving the reliability and overall use of the entire power system (generation, transmission, and distribution [T&D]). In addition, it can provide services to solve more localized power quality issues and reactive power support. The need for storage.
