“Ion bi-layer cell architecture is made of inexpensive, nonflammable materials and use of a lithium metal anode has been able to meet next-generation performance metrics, including high-energy density, strong cycling performance, wide temperature range, and fast charging all at room temperature and without compression,” he said. This architecture makes Ion’s solid-state electrolyte compatible with a wide range of existing and next-generation cathode chemistries.” The dense ceramic electrolyte separator is connected to a porous ceramic electrolyte scaffold,” explained Ovadia. “The porous scaffold acts as a “sponge,” creating uniform and continuous pathways for lithium metal plating without external volume change, while the dense layer acts as a solid-state separator blocking lithium metal dendrites – thereby avoiding the need for compression and preventing short circuits. “Ion’s unique technology unlocks the power of solid-state batteries through its patented Bi-layer cell design. Ovadia noted that Ion is working on a variation to the core product meant for stationary storage applications. Neil Ovadia, Ion’s vice-president of operations, told pv magazine that the company can target multiple markets, ranging from defense to consumer products to electric vehicles and stationary grid storage.
This reduces typical lithium-ion battery defects, and works with existing and next-generation cathode chemistries, avoiding the use of critical raw materials like cobalt, nickel, and gold. The key differences to other solid-state and next-generation batteries is a bi-layer cell design. Ion Storage is developing solid-state batteries and aims to produce 10 MWh per year and generate commercial revenue by the end of 2023. The company aims to develop factories to reach mass battery cell production.
