Electric cars need batteries three or four times better than current that would store as much energy per kilogram as the hydrocarbon fuel used in a conventional car.
The only battery technology that comes close to matching the energy density of petrol is lithium-ion’s close cousin – lithium-air cell.
The lithium/air couple has a theoretical energy density that is close to the limit of what is possible for a battery (~10,000 Wh/kg).
Recent invention of the protected lithium electrode (PLE) by PolyPlus could be approaching commercial reality.
- While still in development is expected to achieve much higher energy density than commercial Li-ion chemistry.
- Use of a solid electrolyte membrane in advanced Li/Air technology also eliminates self-discharge, leading to exceptionally good shelf life and maintenance of high quality inventory over time.
- PolyPlus possesses extensive intellectualproperty in the invention of protected electrodes and battery chemistries enabled by them, including issued and filed U.S. patents, international patents and PCT applications, as well as thorough know-how on the fabrication and use of protected electrodes in battery cells.
