Electrovaya announces promising solid-state battery results as it eyes EV markets

Lithium-ion battery manufacturer Electrovaya has achieved breakthrough performance results for its proprietary solid-state hybrid battery (lithium metal) technology.

Tests at its Electrovaya Labs division showed the company is on track to meet its automotive targets for lithium metal and solid-state batteries.

Coin cell samples reached 300 cycles with minimal degradation under standard room temperature conditions— showing the technology’s promise for passenger automotive applications, which targets 800 cycles with 80% capacity retention.

Pouch cells using Electrovaya’s proprietary solid-state hybrid battery technology were cycled at C/5 rates at room temperature at 100% DOD, no external pressure on cells.

Electrovaya has also scaled to single, two-layer and four-layer pouch cells, which have been cycling at room temperature with no external pressure and are following the same trends as the coin cells, say the Canadian firm.

Electrovaya aims to scale up and manufacture these cells using available methods, and is scaling its process to enable development of larger pouch cells, and accelerating efforts to reach commercial scale for its solid-state hybrid technology.

Battery certification
Earlier this month, Electrovaya completed UL2580 certification for 28 models of its 48V lithium-ion batteries.

Dr. Raj DasGupta, COO of Electrovaya, said: “Our 48V batteries went through extreme testing at various UL third party labs, and we are pleased to report the highly positive results.

“Receiving UL certification for so many new products is an important milestone as we work to expand market share for our batteries, which provide customers with unique safety and longevity without compromising energy and power.”
