LiET’s Aluminum Graphite Dual ion Battery (AGDiB)
LiET are commercializing an entirely new, environmentally friendly, low-cost battery that overcomes many of the problems of lithium ion batteries (LIBs). Our battery technology represents a revolutionary step forward for the clean energy industry. The commercialization of this new battery type will significantly enhance the performance of portable electronic devices, electric vehicles and renewable energy storage systems.
The main components of a battery are its two electrodes—a positively charged cathode
and a negatively charged anode—and an electrolyte. Conventional lithium-ion batteries
have an anode made of graphite or other carbon materials; a cathode made of a lithium
metal compound; and a lithium salt electrolyte.
While the name “lithium-ion battery” is the common term for all types of lithium
batteries, there are many variations. For example the cathode material; any number of
different materials are used today, including lithium cobalt oxide, which is widely used
in cell phones and notebook PCs, lithium manganate which is used by new energy
vehicle makers, as well as lithium nickel oxide, lithium iron phosphate, and systems
that combine nickel and manganese with a base of lithium cobalt oxide.
The major variation of LiETs, AGDiBs are (1) the use of graphite cathode (2) aluminum counter electrode (3) conventional lithium salt and carbonate solvent as the electrolyte.
As a result, our new aluminum-graphite dual-ion battery (AGDiB) offers significantly reduced weight, volume, and fabrication cost, as well as higher energy density, in comparison with conventional LIBs.
Compared with conventional LIBs, this battery (AGDiB) shows key advantages in specific density (~1.3-2.0 times), and energy density (~1.6-2.8 times).
Lithium batteries electrodes are prone to exploding – in the office, on the road or
in your pocket. The advantages of aluminum used by LiET as the electrode are that
aluminum is not flammable, so unlike traditional LIBs our new battery won’t catch
fire, even if you drill a hole through it.
Demand for LIBs is booming. Disposing of all of these batteries creates major
environmental problems, since most batteries contain toxic metals in their electrodes
that are non-recyclable. Unlike most batteries, the AGDiB contains no toxic metals
its electrode materials consist only of aluminum and graphite, while its electrolyte is
composed of conventional lithium salt and carbonate solvent.
Aluminum is the most abundant metal in the Earth’s crust making it much cheaper
than lithium and very importantly, infinitely recyclable, without losing any of its
integrity, in addition, the commercial recycling can be achieved from start to finish
in less than 2 months.
Landfills across the globe continue to drown with infinite numbers of aluminum
soft drink cans, beer cans and every other type of aluminum based product imaginable,
which, when not treated correctly when incinerated, contaminate the air with toxic
compounds that can take up to 500 years to fully decompose. However by recycling
already-manufactured aluminium materials and applying them to our batteries,
precious land space can be cleared by recycling and because aluminum is not toxic,
without any environmental damage to the environment!
Alongside the billions of small lithium batteries that power our assortment of electronic
gadgets that we can’t live without today, as the world’s vehicles, homes and power
stations make the transition to clean energy, according to the Freedonia Group, world
battery demand is expected to rise 7.7% annually, reaching US$120 billion by as early
Replacing traditional LIBs with our AGDiBs would go a long way to resolving the
environmental hazards from discarded lithium batteries.
The barrier to mass market adaptation of lithium-ion batteries in automobiles for example is cost: lithium-ion is still far too costly and will remain so. Demand for lithium is driving up prices. In 2014, lithium prices grew 20% and in 2015 battery grade lithium spot prices in China surged from $7,000 per ton in the middle of the year to a staggering $20,000 per in early 2016.
Market consumption is anticipated to triple from 160,000 metric tons to 470,000 metric tons by 2025. And even looking at a very conservative increase in demand for EVs of just 1% of the their current market share, lithium demand will increase by 70,000 metric tons—double current levels.
Aluminum is the most abundant metal in the Earth’s crust and is much cheaper than lithium. The AGDiB’s electrode materials consist of environmentally friendly low-cost aluminum and graphite only, while its electrolyte is composed of conventional lithium salt and carbonate solvent.
Compared with conventional LIBs, our batteries can be produced 50% cheaper than current LIBs.
Another barrier to entry for LIBs in key sectors is supply constraints for lithium, which is a major factor contributing to sky high lithium prices.
Arguably the leading EV maker today is Elon Musk’s Tesla Motors (NASDAQ:TSLA). When Elon Musk announced the opening of their new gigafactory he was quoted as saying “In order to produce a half million cars per year…we would basically need to absorb the entire world’s lithium-ion production.” And that is just one company in the auto sector; demand for consumer electronic devices is exploding, as is demand for lithium for commercial scale clean energy and off grid storage.
Aluminum as we just noted is the world’s most abundant metal and unlike lithium infinitely recyclable, without losing any of its integrity. Our AGDiB removes the barriers to entry not only in the automobile industry, but reduces the cost of batteries for consumer electronic devices and makes renewable energy storage on a mass scale more cost effective.
