The tech is real and not just for primary batts. The tech was "invented" the same way humans usually "invent", by trying everything and discovering universal principles, but now we can try faster

Wildcat Discovery Technologies Discloses Fundamental Advances in Rechargeable Battery Materials Technology
Newly developed 5-volt electrolyte, cathode material boost battery performance 25-65 percent in cars, electronics, other applications
SAN DIEGO--(BUSINESS WIRE)--Fundamental advances in rechargeable battery technology disclosed today by Wildcat Discovery Technologies could result in battery performance improvements of 25 to 65 percent or more in electric cars, portable electronics, military, medical devices, and other demanding applications.
â€œThis is a breakthrough discovery by our development team, which can lead to batteries capable of storing much more energy than current materials allowâ€
Wildcat has developed a pair of new materials that set new standards for the rechargeable battery industry, by providing unprecedented energy density of more than 675 Wh/kg while operating in full cells at 5 volts â€“ levels beyond todayâ€™s industry standards.
Wildcatâ€™s EM1, a novel 5V electrolyte formulation, and CM1, a new high voltage cathode material, have been shown to deliver a 25 percent improvement in gravimetric energy density, and a 61 percent improvement in volumetric energy density in the electrode, compared with existing state-of-the-art battery materials with comparable attributes. Thus far, batteries made with EM1 and CM1 have expected power and safety performance comparable to lithium iron phosphate (LiFePO4), while also handling more than 100 charge/discharge cycles in full-cell testing.
â€œThis is a breakthrough discovery by our development team, which can lead to batteries capable of storing much more energy than current materials allow,â€ said Wildcat CEO Mark Gresser. â€œWhen batteries hold more energy, it creates new options for design engineers - electric cars can go farther, tablets, laptops and smartphones can be smaller with no loss of runtime, soldier packs can be lighter, and implanted medical devices can last longer before the need for replacement surgery. And while our initial tests have shown a 61 percent improvement in energy density, this is just the beginning â€“ because the EM1 electrolyte is stable at 5-volt operation, it opens the door to development of a new world of cathode materials that should bring even greater advances.â€
Gresser added that the new materials are fully compatible with industry-standard anode materials.
The EM1 electrolyteâ€™s high-voltage capability is of special interest for the automotive sector, where cell development has been restricted by the inability of existing electrolyte formulas to cycle at high voltages. Current EV systems based on low voltage cells require complex and expensive pack designs and battery management systems. EM1 enables high voltage systems which are expected to reduce required cell quantities 30-40% vs. competing materials like LFP and NMC. Fewer cells and simpler pack designs translate into substantially lower costs for auto makers.
The materials were developed using Wildcatâ€™s proprietary high-throughput synthesis and screening platforms, which enable rapid discovery and development of advanced materials. For the CM1 cathode material alone, Wildcatâ€™s R&D team synthesized and evaluated more than 3000 materials in just eight months; this research may have taken years using conventional methods.
Wildcat is actively seeking licensees and partners for further development and commercialization of EM1 and CM1 and successor materials. Sample quantities of up to 1 kilogram will be available as of April, 2011.

We'll never know if EEStor is real...but keep an eye out for EM guns that don't use homopolar generators
