as well so systems designers should look carefully at the testing protocols. By doing so, we enable ultracapacitors with up to 35Wh/L (5x EDLC) and 25x lower build cost vs. EDLCs—addressing the two most prominent ultracapacitor weaknesses. And this chemistry and architecture allow low-cost, ultra large scale manufacturing.

Co-founded by MIT’s Dr. Yet-Ming Chiang, 24M’s Chief Scientist, the company is leveraging existing, preferred energy storage chemistry but using a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs.

The future grid will face significant challenges by providing clean power from intermittent resources to a much more dynamic load. To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. Among the most important factors are capital cost and life-cycle cost.

PbC batteries are multi-celled asymmetrically supercapacitive lead-acid-carbon hybrid batteries. Like a lead-acid battery, it comprises a series of cells. NS originally built NS-999 in early 2009 with lead–acid batteries; however, the lead–acid system consistently failed field testing.

Designed to operate as a ‘Plug-In Hybrid Electric Vehicle’ (PHEV), the development team retained the existing conventional front-wheel-drive system of the Combo but added an electric drive, powered via Exide’s low cost advanced lead acid batteries, to the rear wheels.

Its goal is to become a full-service Tier 1 supplier of vehicle battery systems capable of designing and delivering Li-ion cells, modules and packs along with the supporting battery monitoring, wire harnesses and thermal management components. and help optimize the battery pack so it doesn’t end up being over-designed based on one criteria.

Since battery weight in a boat isn’t much of an issue, they can use low cost lead acid batteries, yet still get all the power and energy they need. Plugging into the SoCal grid, in this case, SoCal Edison, this PHEV tug is significantly cleaner than its diesel burning brethren. Smoke, that is.

at least, the recycling infrastructure for the well-established lead-acid batteries is robust. lead-acid batteries have a far better recycling rate than even aluminum bottles — over 90% of lead-acid batteries are recycled. None of the new electric cars are planning to use old-tech lead acid batteries.
