Electrovaya Announces Breakthrough Performance for Proprietary Solid State Hybrid Battery Technology
2022-04-13 08:02:00 AM ET (ACCESSWIRE)
On track to meet automotive targets for lithium metal & solid state batteries. Achieved ~94% capacity retention after 300 cycles, scaled to multilayer pouch cell, demonstrating larger cell formats
TORONTO, ON / ACCESSWIRE / April 13, 2022 /Electrovaya Inc. ("Electrovaya" or the "Company") (TSX:EFL)(OTCQB:EFLVF), a lithium-ion battery manufacturer with differentiated intellectual property that allows heightened safety and improved longevity, today announced that it has achieved breakthrough performance results for its proprietary solid state hybrid lithium metal battery technology at its Electrovaya Labs division. The results support opportunities to significantly expand Electrovaya's product offerings and customer base over the long term.
Coin cell samples reached 300 cycles with minimal degradation under standard room temperature conditions (see Figure 1). These results highlight the ability of the technology to meet passenger automotive applications, which target 800 cycles with 80% capacity retention.
Figure 1: Capacity retention of multiple samples using Electrovaya's proprietary solid state hybrid battery technology. Coin cell samples were cycled at C/5 rates at room temperature at 100% DOD and have crossed 300 cycles with ~94% capacity retention.
Electrovaya has also achieved scaling to single, two-layer and four-layer pouch cells. These cells have been cycling at room tempera ture with no external pressure and are following the same trends as the coin cells. The first 40 cycles of a pouch cell sample are shown in Figure 2.

"The fact that Electrovaya has achieved these results without the use of external pressure on the cells and at room temperature showcases the strength of the technology relative to other solid state and lithium metal cell technologies, and will also allow easier adoption in automotive battery pack designs," said Dr. Raj Das Gupta, COO of Electrovaya.
Electrovaya has extensive experience in manufacturing cells, and the aim is to scale up and manufacture these cells using available methods. The Company is scaling its process to enable development of larger pouch cells, and is accelerating efforts to reach commercial scale for its solid state hybrid technology.
