Battery Safety Matters.

It’s one of the most important considerations when choosing energy storage for your home or business.

Luckily, with us, there isn’t much you have to consider.  Aquion batteries are the safest in the world, giving you peace of mind along with your energy independence.

Aquion’s batteries are not flammable, corrosive, or explosive within any environment, states of charge, or use condition as specified in Aquion’s specification sheets and users manuals.

Aspen batteries have a safe water-based electrolyte, as compared to the flammable organic solvent in lithium ion batteries and caustic sulfuric acid in lead acid batteries. This water-based system moderates the maximum temperature that the battery can reach – it is impossible for any internal reactions to drive the battery above 100°C, since at this temperature, all of the water will evaporate leading to an open circuit condition.


We tried to light our batteries on fire.

Just to prove how safe AHI chemistry is, because you’ve seen the news reports on battery fires. But thermal runaway events are simply not possible in the AHI chemistry for the reasons described above as well as the fact that lithium metal, dendrites, and SEI layers cannot form because they are all water soluble species and cannot build on the electrode surface and lead to short circuits. See for yourself:

We also drilled holes in our batteries.

Again, to show how much safety matters to us. Battery punctures can cause dangerous explosions or toxic material leakage. To test for this, manufacturers perform a standard nail penetration test. We conducted our own version of this test– but with a drill– on an energized AHI battery. In most cases, a lithium-ion battery will explode immediately. Meanwhile, the benign, non-toxic materials inside the Aquion battery cannot explode, and the leakage is not harmful. Watch the side-by-side comparison:

Battery safety is a top priority for us, and it should be for you, too.

We keep up an ongoing discussion about safe energy storage issues on our blog. Check out some of these posts for more information:
