This is an interesting technology brought to our attention by one of our readers (sfuchs)
The video is really worthwhile watching especially taking to the battery with a pick axe
A True Innovation in Batteries
The HE3DA® nanotechnology utilizes the high charge and discharge speed of nanomaterials, resulting in superior safety and many new properties of Li-accumulator modules that were heretofore unthinkable.The HE3DA® nanotechnological platform moves the frontier of lithium accumulators decades forward.
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
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.
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
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.
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.
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.
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:
Stabilization of renewables
Power back up
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.
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. The batteries meet all necessary requirements, including operating temperature.
50V car battery
50V car batteries will allow many innovations in the car industry. When car makers are ready, HE3DA will be able to supply the batteries..
Accumulators for electric vehicles
HE3DA is a step in the direction toward a safe and affordable high-power accumulator with a fast charging time. Currently achieved parameters of HE3DA battery for electric vehicles are:
Energy density of battery system 520 Wh/liter
Efforts to achieve parameters which are now only seen as the frontier of development are the engine of future development. Therefore, we want to focus on our R&D as well as production of special batteries that will push our abilities even further.
