EEStor, the developer of a new high-power-density ceramic ultracapacitor (the Energy Storage Unit—EESU), has broken a long public silence and announced reaching two key production milestones. First, its automated production line has been proven to meet the requirements for precise chemical delivery, purity control, parameter control and stability.

Second, EEStor has completed the initial milestone of certifying purification, concentration, and stability of all of its key production chemicals—notably the attainment of 99.9994% purity of its barium nitrate powder.

The company anticipates that the relative permittivity of the current powder will either meet and/or exceed 18,500, the previous level achieved when EEStor produced prototype components using it engineering level processing equipment.

The EEStor ESU is projected to offer up to 10x the energy density (volumetric and gravimetric) of lead-acid batteries at the same cost. In addition, the ESU is projected to store up to 1.5 to 2.5 times the energy of Li-Ion batteries at 12 to 25% of the cost.

And they intend to ship their first production ultracaps to Zenn sometime this year.
