An injection of graphite foam is giving new life to the venerable lead acid battery, according to Firefly Energy.
The Peoria, Ill.-based company has come up with a way to coat the membrane, a fan-like lead lattice that allows the battery to generate electrons, with graphite foam. This change results in a more efficient battery that can extract more electricity from the electrolyte, release more electricity per charge, and endure more charging cycles. The battery also will last longer. The foam gives the membrane a larger surface area for reactions.
Firefly's Oasis batteries are designed for long-haul trucks. … Read more
