LG Energy Solution aims big after IPO

LG Energy Solution was listed on the main Kospi bourse in January, 30 years after the company took its first step as a pioneer in the rechargeable battery business in 1992.

Its next goal is to become “a company that is trusted and loved by customers.”

LG Energy Solution’s initial public offering set several records, raising capital of more than 10 trillion won ($8.3 billion) and attracting 114.1 trillion won in deposits from some 4.4 million retail investors.

As the first Korean company to have begun research on storage batteries, LGES has invested 5.3 trillion won in research and development over the past 10 years, and as a result, owns some 22,900 patents in materials, process and core technologies.

With about 3,300 research and development personnel around the world and R&D centers in Korea, China, the US and Europe, LGES owns intellectual properties in not just cells, but also in battery packs and battery management systems.

“It is virtually impossible to develop new batteries independent from LGES’ patents,” an official in the battery industry said.

The “world’s first” technologies and products developed by LGES include a double-layer coating technology that reduces battery charging time, high-nickel NCM (nickel-cobalt-manganese) positive electrode materials and silicon anode materials.

The company also owns various battery platforms from small to large, cylindrical, prismatic and pouch, allowing it to meet customers’ price and performance demands.

Among global secondary cell manufacturers, LGES has the largest global production system.

LGES and General Motors Co. last month unveiled a $2.6 billion plan to build a new electric vehicle battery plant with an annual production capacity of 50 gigawatt hours in the US.

The new factory to be built in Lansing, Michigan, by 2024 will be the two companies’ third joint plant after the first in Ohio and the second in Tennessee, both currently under construction and aiming for annual production capacities of over 35 GWh each.

LGES is also running its own or joint EV factories in Korea, North America, China, Poland and Indonesia to minimize logistics costs and quickly respond to changes in local policy and markets.

Having raised some 10.2 trillion won through the recent IPO, LGES plans to invest 5.6 trillion won in North America, 1.4 trillion won in Europe and 1.2 trillion won in China by 2024, and 645 billion won in Korea by 2023 to expand production capacity.

With a strong commitment to environmental, social and corporate governance, LGES is taking steps to introduce renewable energy to drastically cut energy use and minimize greenhouse gas emission in the battery production process.

The company was the first in the industry to join global environmental campaigns RE100 and EV100.

“We are going forward with various battery recycling and reuse projects to establish a virtuous cycle of resources in all of our workplaces worldwide,” LGES vice chairman Kwon Young-soo said.

“For responsible management of supply chains, we will diversify product development and supply sources, and recruit talent regardless of nationality, gender or disability for diversity.”

CHICAGO, March 28, 2022 (GLOBE NEWSWIRE)

NanoGraf, an advanced battery material company and enabler of the world’s most energy-dense 18650 lithium-ion cell, today announced that it won a $1 million development contract from the Department of Defense to produce a more powerful, longer-lasting 4.3Ah lithium-ion battery. The cell will provide U.S. military personnel with enhanced run-time for the equipment they rely on to operate safely and efficiently.

Soldiers carry upwards of 20 pounds of lithium-ion batteries to power communication devices, goggles, helmets, and more. Battery-powered technology helps soldiers achieve their missions, but the weight can result in fatigue and mobility issues, putting soldiers at risk. Improved battery performance is key to the U.S. military’s success and ability to provide excellent communications and keep soldiers safe. NanoGraf’s batteries will continue to improve run time on U.S. soldiers' equipment, resulting in increased overall performance.

This is the second Department of Defense project won by NanoGraf. In 2021, the company developed the world’s longest-running 3.8Ah 18650 cylindrical lithium-ion cell, at 800 watt-hours per liter (Wh/L). This cell will go into volume production in the Spring of 2022.
“When people talk about range anxiety with electric vehicles, it’s about the inconvenience, whereas in the military, it can be about life or death,” said Dr. Francis Wang, CEO of NanoGraf. “We’re honored to have this opportunity to enable enhanced survivability and effectiveness to our Soldiers and Warfighters with greater runtimes for their critical electronic devices.”

In an industry where performance improvements are typically very small, the 4.3Ah will be a dramatic increase in energy density reaching 870Wh/L, and NanoGraf expects no impact on cycle life, shelf life, discharge rate capability, or operating temperature.
The cell will enter into volume production in Q2 2024, and be available for battery pack qualifications and fielding to the Warfighter in late 2024.

Amprius using Silatronix OS3 electrolyte in high-energy-density silicon-anode batteries

29 March 2022

Amprius Technologies, a provider of silicon anode Li-ion battery cells with the Si-Nanowire platform (earlier post) is using Orbia’s Fluorinated Solutions brand Koura’s Silatronix OS3 electrolyte material in commercial lithium-ion batteries. OS3 is the latest generation in performance enhancing organosilicon electrolyte materials available from Silatronix.

The introduction of Silatronix OS3 has seen the battery cells achieve an industry leading energy density of 450-Wh/Kg and 1150-Wh/L (earlier post)—among the highest of any commercial lithium-ion cell in the world. Amprius battery cells achieves this level of energy density by applying its proprietary Si-Nanowire platform, which utilizes 100% silicon in the anode.

"The collaboration between Amprius and Koura on this project has been a partnership which has resulted in outstanding performance of our battery cells, even in challenging environments. Using Silatronix OS3 has helped Amprius achieve the highest energy density of any commercial lithium-ion battery cell in the world."

—Ronnie Tao, Vice President of Business Development for Amprius

Additionally, engineers at Amprius collaborated with Orbia Fluorinated Solutions to optimize high-performance electrolyte containing OS3, enabling the cells to operate with long cycle life in challenging environmental conditions.

Advanced electrolyte materials such as OS3 are a critical component of increasing energy density in lithium-ion batteries, working together with advanced electrode technologies such as Amprius Si-Nanowire.

Koura is a fully integrated fluorine technology company currently executing on a strategy to accelerate technology development in the rapidly expanding lithium-ion battery industry.

Koura notes that OS3 has been proven to deliver strong performance improvements in a wide range of Si-anode based systems including less gas generation; reduced impedance; longer cycle life; and improved high-temperature stability.

OS3 has a strong compatibility with fluoroethylene carbonate (FEC), which is commonly used to provide stability in Si-anode systems. FEC comes with a downside of creating significant gas generation. Silatronix has demonstrated that when OS3 and FEC are combined in a system, OS3 specifically removes gas components associated with FEC, providing an enablement of the electrolyte solution.

Energitettheten er god, men kan ikke stille opp mot de 400 Wh/kg som første generasjon med silisiumanoder fra Sila / G14, som jeg mener hevdes rundt 400 Wh/kg.

At Tesla ikke har fått noe av sitt metallurgiske silisium inn i anoden sin, er skuffende. Funket det kanskje ikke som de hadde tenkt? Sparer de det til neste generasjon?

Kanskje en av REC-partnerne vil se Tesla på kundelisten etter hvert likevel?

Enovix releases 100% silicon anode cells

US battery startup Enovix has newly developed 100% active silicon anode cells for its new-generation 3D silicon lithium-ion batteries, significantly boosting the battery energy density up to 900Wh/l, a lead over that of traditional lithium battery by five years, according to the company's Asia Pacific sales VP Jay Wang.

At the moment, most lithium battery makers still use graphite as main anode material, which has an energy density of only 372mAh/g, far lower than the theoretical density of up to 4,200mAh/g for silicon material. Though they are trying hard to boost the content ratio for silicon material to improve energy density, the ratio is now still under 10%, compared to 100% at Enovix, Wang noted.

Wang stressed Enovix has successfully rolled out 100% silicon active anode cells by tackling all the barriers encountered by traditional lithium battery makers in incorporating silicon material, such as easy expansion and breakage of such material.

He said the company has also incorporated its unique BreakFlow technology, an intra-cell system that significantly increases tolerance against thermal runaway from internal shorts, without compromising high energy density.

Wang also noted that Enovix will mainly target consumer applications for its products, particularly wearable devices, before advancing to EV applications in 2025.

The annual battery market scale for mobile and computing devices is estimated at US$13 billion, including US$3.2 billion for wearable devices cells, Wang said, disclosing that Enovix has started volume shipments to vendors of wearable devices, and will set up a new plant in the US by the end of 2022 before moving to plan a new production base in Asia after 2023.
