Energy sector Balancing and stabilization of high capacity battery systems HE3DA has developed an accumulator suitable for mass application in the energy sector. Its parameters enable utilization for: Peak balancing Frequency regulation Island networks Stabilization of renewables Power back up Volt/VAR control The main HE3DA module for the energy sector has a capacity of 1 MWh and is composed of 125 eight-kWh cells. The total dimensions of the module are 8,6 m3, including all external systems. The modules can be easily fitted into large energy storage systems. The installation of the HE3DA battery system is very simple due to the small number of cells and the innovative BMS concept. The systems are virtually maintenance free. Car industry HE3DA technology can currently be utilized for the automotive industry in the applications . listed below. All these applications will be developed to the production stage at the latest by mid-2016. 12V car battery HE3DA technology enables construction of safe single-cell lithium car batteries.

Therefore, we want to focus on our R&D as well as production of special batteries that will push our abilities even further. Aviation and astronautics Micro-batteries

Flexibility of use The capacity and charge/discharge time of the accumulator can be adjusted by choosing a particular electrode thickness. This allows for tailor-made solutions and a number of applications of HE3DA accumulators and represents a huge potential for development. Ability to construct large cells The HE3DA technology enables construction of cells an order of magnitudes larger than are currently produced by conventional technologies. This is allowed by low production of heat and the ability to cool the cells efficiently by internal cooling of the electrolyte. Safety HE3DA technology is inherently safe. Due to lower internal resistance, robust separators and the absence of any organic materials (except for the electrolyte), the HE3DA accumulator cannot burn or explode due to a short circuit. The battery can operate in a potentiostatic regime, which serves as a protection against overcharging. Technical parameters HE3DA technology offers top-class technical parameters: Battery system capacity up to 500 Wh/liter Kilowatt hour module offers fifteen times higher peak power than currently used technologies. Efficiency above 95% Lifespan 5000 cycles Economic parameters HE3DA technology achieves top-class economic parameters: Low cell production costs: Simplicity of production yields low capital expenditure and production costs. Use of standard production materials and the absence of ballast result in low material costs. Low cost of installation into large capacity storage systems: Low cooling requirements and internal electrolyte cooling. Ability to use a new, simple battery management system. Low operational costs allowed by high efficiency and low O&M requirements. = Low overall electricity storage costs = Mass utilization of batteries in energy sector and other industries. Future development potential Currently used 2D lithium accumulators have reached their technical limits. Many issues still remain, particularly safety. Producers are now focusing mainly on lowering prices, seeking economies of scale by constructing huge production facilities. HE3DA technology is still in an early stage of development. Future development potential is thus one of the greatest assets of HE3DA. Recyclability Today the recycling cost of a battery is approx. 5% of the battery’s value, reflecting the cost of ecological disposal. An HE3DA accumulator is 100% recyclable.

HE3DA technology eliminates the ballast from batteries, and optimizes the qualities of nano-materials and the morphology of electrodes. It enables a much greater thickness of electrodes and offers many new advantages and construction solutions. This technology greatly improves on the safety of lithium-based batteries and allows for a wide range of completely new technical solutions resulting from the so far unachievable technical and economic parameters found in HE3DA batteries. HE3DA technology allows accumulator capacity parameters and charge/discharge times to be set by adjusting the thickness of electrodes. Other parameters of the accumulato such as cost, robustness, operating temperature, weight etc can be adjusted by selection of production materials.
