A brine battery uses a concentrated salt solution as its electrolyte. They are not flammable and are more easily recycled than batteries that use toxic or flammable materials.

History

In 2008, Carnegie Mellon professor Jay Whitacre founded Aquion Energy and received venture funding from Kleiner Perkins Caufield and Byers. He won the 2015 Lemelson-MIT Prize, a $ 500,000 award, to create a brine battery of the company. They are the first and only battery manufacturer to meet all the stringent criteria to get the Cradle-to-Cradle (Bronze) certification.

Design

Aquion Energy

Aquion Energy batteries are classified as standard items without special handling required in shipping. It has no side reactions that reduce life while not in use. This is robust for every profile of cycling variables and long duration intervals while partially filled. Maintenance of cycling to maintain performance/life is not necessary. The optimal operating temperature range is -5 Â ° C to 40 Â ° C and slightly affected by changes in operating temperature. It operates without additional load or external power supply. Chemical properties are not susceptible to thermal runaway. Active thermal management is generally unnecessary, unless given extreme environmental temperatures. The mechanical material can be recycled in a normal recycle stream. Chemicals can be removed without special equipment or containers.

Water in salt

Different designs use electrolytes that have a water-to-water ratio of six to one, almost saturated, so they can also be called batteries water in salt .

Solid electrolyte interfase

The designers claim that they have induced the cells to form Solid-electrolyte interfaces, the first for aqueous electrolytes. SEI allows the battery to operate at higher voltages and self discharge more slowly. A high salt concentration allows the interphase to form. This raises the maximum voltage for such a battery from 1.23 V to about 3 V. At 2.4V, the battery-specific energy is around 100 Watthour/kg and it exhibits consistent performance over 1,000 charge/discharge cycles.

The device is operated with nearly 100% coulombic efficiency at low (0.15 C) and high (4.5 C) discharge and charge rates.
