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.

Balqon Corporation introduces HIQAP industrial lithium-ion packs to replace lead-acid batteries

Green Car Congress

Balqon Corporation, a developer of heavy-duty electric vehicles, drive systems and lithium battery storage devices, has introduced high-capacity lithium-ion batteries as an alternative to the current industrial deep cycle lead acid batteries. HIQAP batteries include large format 1000 Ah and 700 Ah, 3.25

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.

DIY Electric Car

Next will be the design and implementation of the electronics? m still planning on using # 12 gp 27 deep cycle batts as my power pack I hope that gets me at least 40 mi. Tomorrow I will raise the drive wheels and give her a good testing of the drive train. I do well with the heavy work, soldering, and wiring, but I don?

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.
