Update on Nano One’s Breakthrough in Battery Longevity
November 24, 2020 (Source) — Dr. Stephen Campbell, CTO of Nano One® Materials Corp. (TSXV: NNO) (OTC PINK: NNOMF) (FSE: LBMB) is pleased to present Nano One’s latest durability test results confirming that its high-voltage cobalt-free battery is also stable at elevated operating temperatures required for automotive, power tool and energy storage applications. These results augment ambient temperature results announced on October 13, 2020 and further demonstrate the longevity and stability of Nano One’s Lithium Nickel Manganese (LNM) battery system.
“Nano One has achieved over 500 fast charge and discharge cycles at 45°C,” said Dr. Campbell, “in an innovative battery design that pairs its high-voltage LNM cathode with a conventional electrolyte and a graphite anode. We have also reached 1000 fast charge and discharge cycles at 25°C demonstrating that issues of excessive gassing, anode contamination and poor cycling may be overcome.”
Nano One’s proprietary LNM battery enables the benefits of increased voltage, elevated operating temperatures and fast charging, by eliminating failure from gassing in the first few cycles and failure from manganese contamination of the anode in the first 100 cycles.
Dr. Campbell added “Nano One’s LNM battery innovation breaks through the barriers that have hindered the commercialization of LNM cathode materials in both conventional liquid and advanced solid-state batteries.”
LNM, also known as high voltage spinel (HVS), is a cobalt-free, low-cost cathode material that operates at 4.7 volts. This voltage is 25% higher than commercial high nickel cathodes, providing improved efficiency, thermal management and power. Battery pack models suggest that LNM cathodes may reduce costs by over 30% as compared to high nickel NMC materials [Wentker et al, Energies 12 (2019) 504-521].
Inspired by ESG (Environmental, Social, and Governance) concerns, the Nano One patented One Pot process combines sulfate-free feedstocks with lithium carbonate, additives and coating materials in a single reaction to, ultimately, form coated single crystal cathode materials with enhanced durability. This process further improves LNM economics and environmental sustainability by eliminating cobalt feedstock and sulfate waste and by reducing energy and water consumption.
The LNM cathode (LiNi0.5Mn1.5O4) was tested with a graphite anode and conventional electrolyte in a 20-layer pouch cell (4.75V 126mAh 0.592Wh) charging and discharging 12 times per day for 1000 cycles at 25oC and for 500 cycles at 45oC. This demonstrates enhanced durability under operating conditions that are relevant to automotive, power tool and energy storage applications in a cobalt-free, high voltage battery.
Nano One’s LNM cathode is a leading candidate for next generation lithium-ion and solid-state batteries because its durability and dimensional stability enable a stable interface with both liquid and solid electrolytes. Several independent evaluations are currently underway within the automotive and battery supply chain demanding lower cost, higher voltage and improved safety without compromising longevity and performance.
“Nano One has developed processes, materials and now a battery innovation to enable our novel cathode materials for the future of lithium-ion batteries,” Dr. Campbell added. “We are excited by the commercialization and partnership opportunities of this latest breakthrough.”
