a unique fabrication method of a three-layer membrane- electrode assembly (MEA) by concurrent electrophoretic deposition of two electrodes directly on each side of an electrically insulating and
ion-permeable membrane. 
The MEAs manufactured by the simultaneous EPD method can be used in various energy devices, including, inter alia, batteries, fuel cells, flow cells, and super capacitors.
UNMET NEED
Printed batteries are an excellent alternative to conventional batteries for an increasing number of applications such as radio frequency sensing, interactive packaging, medical devices, sensors, and wearable electronics.
OUR SOLUTION
Concurrent electrophoretic deposition (EPD) of positive and negative battery electrodes (LFP and LTO) on opposite sides of a commercial nanoporous membrane (Celgard 2325) results in the formation of a three-layer-battery structure. The cell comprising this electrophoretically deposited structure ran for more than 150 cycles with 125-140mAh/g capacity, which approaches the theoretical value of lithium iron phosphate.
ADVANTAGES
The energy storage devices which can be manufactured using EPD can be free form-factor, green, and will enable completely new products and innovations in a wide range of applications: from wearables to point-of-care devices in our increasingly interconnected and mobile modern society.

APPLICATIONS
Products, such as activity trackers, smart clothing, printed electronics and e‐skins are part of a large eco‐system of devices commonly referred to as ‘Internet of Things’. ‘
These smart devices will sense, communicate with each other, take action and provide information to the user. The battery requirements for these products should have small footprint, flexibility and unique form factor.
In addition to typical characteristics such as low cost and high energy density.
