New Battery Technology

[rgleason]

This thread is devoted to highlighting and discussing new battery technology and types that are promising and preferably in production.

One likely possibility is http://aquionenergy.com/
Stainless Steel, Cotton, Manganese Oxide Electrode, Carbon Titainium Cathode, and Saltwater. Very safe, long life, good partial state, sustainable, good temp tolerance, low power density and delivery, inexpensive. Good for solar, not for fast charging.

"Aquion’s batteries use sodium ions from saltwater as their electrolyte. Electrical current moves through this brackish liquid from positive electrodes based on manganese oxide to negative ones based on carbon. The batteries are large and operate slowly, but they are also manufactured cheaply, using repurposed manufacturing equipment. Last week Aquion announced $34.6 million in funding to help it scale up production."

"The batteries cost about as much as lead-acid ones, which are sometimes used now, but they last twice as long, effectively cutting the long-term costs in half (see “Demo: Storing the Sun”). Other long-lived batteries exist, but they cost far more than lead-acid batteries.
The new energy storage technology could be crucial to making renewable energy more viable, especially in remote locations. "

Where can we buy these?

I believe that since emerging from Chapter 11 that they're focus is only on large alternative energy companies, telcos and grid suppliers.

LTO Batteries not for cruisers due to discharge inefficiency and expense.

Are we to presume the subject battery technology to be that which would have significant relevance as to marine applications, i.e., high energy density as to volume and weight, non-flammable, non corrosive, reasonable cost - specify currency per kilowatt hour, etc.

There being many battery technologies that would have terrestrial relevance but little marine benefit, e.g., rapid charging requires major source of power.

Please detail your areas of interest.

The statement should probably include "use in Marine applications".


The ability to charge faster might lead towards a larger alternator or generator and a smaller battery bank in our case. Also it would allow transient boats to stop at a marina for a quick full charge. There are use cases in the marine environment.

Yesterday IBM announced a new battery discovery which might prove very important. It is apparently a better lithium ion battery which uses a non-flammable electrolyte and suppresses formation of lithium metal dendrites during charging, thus eliminating the fire hazard inherent in current lithium ion designs.



Here's a link to IBM's announcement:

With the limiter areas we have available on a boat for mounting solar panels and our high dependence upon batteries for electrical power availability fast recharge is a very important consideration.

This looks like it might be a reasonable House Battery.

Maintenance Free - No watering required, with long 2-year shelf life that has low self-discharge rateMaximized

Cycle Life - Affordable high performance with 3000 Cycles @ 50% depth of discharge
Super-Fast Charging - High charge rates allow the 2100 PLC to go from 50% up to 90% state of charge in under an hour
Exceptional Value - Pay less up front and get lower overall cost per kWh cycle than other lead acid batteries
Advanced Technology - PLC high power, energy dense batteries have a specially formulated carbon additive that enhances the overall battery life
Partial State of Charge Applications - Pure lead + carbon = greater cycle life in both PSoC and non-PSoC off-grid operations.

In PSoC/daily cycling applications, the batteries do not need to be fully charged every day, and they will still get 3000 cycles.
5 Year Limited Warranty

AltE Energy - KiloVault 2100 PLC 2100Wh 180 Ah 12V Advanced AGM Battery
$500 127lbs, Max charge 140a Recommended charge 100a, 22"x 5" x 12.6"

pure lead carbon sealed AGM deep cycle solar battery, for cycling applications. KiloVault 2100 PLC is a cost-effective, maintenance-free battery that offers superior performance in Partial State Of Charge (PSoC) applications, combining pure lead and advanced carbon technology for extended battery life and rapid charging. The batteries are designed for residential or light commercial off-grid, backup, or self-consumption applications.

Does anyone have experience with them? Hits a lot of points.

Fast Charging.
Reduced PSOC problems.
No BMS needed as for LFP
Compatible with most alternators provided it has temp sensors and perhaps belt manager.
Price.

There have been number of lead-carbon batteries coming into to the market recently from different mainstream manufacturers. To date, they seem like a worthwhile replacement for AGMs.

Carbon agm batteries trying to be FireFly. Maybe they are good, but at same price as FF who wants to be the experiment?
