GM, LG Energy target commercializing manganese-rich batteries for EVs
This story was originally published on Automotive Dive. To receive daily news and insights, subscribe to our free daily Automotive Dive newsletter. Battery engineers at General Motors and its joint venture partner LG Energy Solution have developed an improved lithium manganese-rich (LMR) prismatic battery cell design for the company's future electric vehicles, the automaker announced in a May 13 press release. The LRM battery chemistry uses a higher percentage of lower-cost manganese to replace Cobalt, a critical raw material for EV batteries, making them less costly to produce while still delivering high energy density. GM aims to be the first major automaker to deploy LMR batteries in EVs. Its Ultium Cells joint venture with LG Energy plans to start commercial production of the battery cells in the U.S. by 2028 for full-size electric trucks and SUVs. GM's current EV models use nickel manganese cobalt aluminum oxide (NMCA) batteries, which contributes to improving driving range, but are costlier manufacture. LRM battery chemistry, on the other hand, can help GM make its future EVs more affordable. A high nickel battery cell typically consists of roughly 85% nickel, 10% manganese and 5% cobalt, according to GM. But LMR cells contain around 35% nickel, 65% manganese, and 'virtually no cobalt,' which can significantly reduce costs. In addition, GM says its LMR prismatic battery cell design has 33% higher energy density compared to the best-performing lithium iron phosphate (LFP) or manganese cobalt aluminum oxide (NMCA) cells used in many EVs on the road today, and at a comparable cost. The new LRM battery cells are not intended to replace GM's current batteries. Rather they will be used for some electric models along with high-nickel and iron-phosphate cells for others. According to GM, the lower cost LRM prismatic cell batteries will primarily be used to expand customer choice in the electric truck and full-size SUV markets. 'We're pioneering manganese-rich battery technology to unlock premium range and performance at an affordable cost, especially in electric trucks,' said Kurt Kelty, VP of battery, propulsion, and sustainability at GM, in the release. 'As we look to engineer the ideal battery for each vehicle in our diverse EV portfolio, LMR will complement our high-nickel and iron-phosphate solutions.' GM is targeting driving ranges of over 400 miles for its full-size electric trucks and SUVs equipped with LRM batteries, while achieving significant cost savings compared to today's high-nickel battery cells the automaker is currently using. The automaker said it began researching LRM battery cells a decade ago, which included prototyping cells at its Wallace Battery Cell Innovation Center in Warren, Michigan. The automaker accelerated its research in 2020 as its engineers collaborated with partners including LG Energy to achieve advancements in battery cathode materials, electrolytes, additives, form factors and assembly processes. GM said researchers overcame LMR's limitations in performance and durability that made them impractical for commercial use, according to the company. 'We've worked with our suppliers to optimize the materials in our LMR cells, adding proprietary dopants and coatings, along with particle engineering, process innovations, to achieve the right energy density and arrangement of battery materials inside the cell to keep them stable,' said Kushal Narayanaswamy, director of advanced battery cell engineering at GM, in a May 13 blog post. By the end of 2024, GM said its researchers coated roughly one metric ton of LMR cathode material at the company's Wallace Battery Cell Innovation Center, which included testing hundreds of large format prismatic cells in 18 different prototypes and three cell dimensions. In total, the tests were equivalent to 1.4 million miles of EV driving, according to GM. Unlike the 4680 cylindrical cell format used by Tesla for the Model Y, prismatic cells can be stacked closer together inside an EV's battery pack. Their flat design uses less space compared to cylindrical cell batteries, leading to higher energy density, as more cells can fit into each EV battery pack. The cells can also better dissipate heat for improved cooling performance with an outer case typically made of aluminum. 'That makes them substantially more efficient to package in full-scale trucks and SUVs,' Narayanaswamy said. Prismatic cells also require fewer components to assemble battery packs, which contributes to lower costs. The design can reduce battery module components by 75% and total pack components by 50%, according to GM. Pre-production of LRM battery cells is expected to begin at an LG Energy Solution facility by late 2027. The final cell design will be validated at GM's new Battery Cell Development Center in Warren, Michigan, that's expected to be operational by 2027. The batteries will also be validated at an unnamed LG Energy Solution facility before series production begins. 'We're excited to introduce the first-ever LMR prismatic cells for EVs, the culmination of our decades-long research and investment in the technology,' said Wonjoon Suh, executive VP and head of the Advanced Automotive Battery division at LG Energy Solution, in the release. 'GM's future trucks powered by this new chemistry are a strong example of our shared commitment to offering diverse EV options to consumers.'

Aging population focus of town hall meeting
CUMBERLAND — The public is invited to a town hall in Allegany County next week to discuss a plan for Maryland's aging population. Five years from now, more than a quarter of the state's residents will be at least 60 years old. That demographic, according to the Maryland Department of Aging, has increased over the years. In 2000, the 60 and older population represented 15% of all Marylanders, and by 2020, that percentage grew to 23%. Because people in the state are living longer than ever, Gov. Wes Moore in January 2024 signed an executive order that mandates development of Longevity Ready Maryland, a 10-year plan 'to address the challenges and maximize the benefits and opportunities of an aging society,' the Department of Aging said.

The LRM plan aims to 'lead to more integrated service delivery models and provide a voice to those who participate to ensure the needs of all Marylanders are heard,' MDOA said. Goals of the plan include formation of a longevity 'ecosystem' that connects a network of organizations, businesses, government agencies, health care providers, researchers and key stakeholders to work collaboratively with older Marylanders to enhance quality of life. LRM Summary (Maryland Department of Aging) Economic opportunities through an age-inclusive workforce and multigenerational consumer participation will be promoted. Other priorities in the plan include affordable housing, health care, retirement planning, health, wellness and mobility. Implementation of the plan is set for July 2025. According to the Department of Aging, how long and how well Marylanders live depends largely on their ZIP code. 'Where someone lives can significantly influence their life expectancy and overall well-being,' MDOA Communications Director Barbara Sigler said. Factors including access to health care, quality of education, income levels, environmental conditions, and community safety vary widely across the state, she said. 'These differences can create disparities in health outcomes and life expectancy,' Sigler said. Many rural areas in Maryland, including Dorchester, Allegany and Kent counties, have a much higher percentage of lower-income older adults, she said. Gender also influences how well Marylanders age, with women earning 14% less than men in the state — a pay disparity 'that is even more pronounced for Black and Hispanic women,' Sigler said. 'Because women are also much more likely to be caregivers to children and older adults, it impacts their ability to save for the future, care for themselves and invest in Social Security,' she said. Part of Longevity Ready Maryland's focus is on creation of an equitable and inclusive environment for all Marylanders, including addressing economic disparities faced by women, Sigler said. 'While its primary goal is to prepare Maryland for an aging population, it also emphasizes improving economic opportunities for women, particularly those in caregiving roles and the direct care workforce, where women are disproportionately represented and often earn below a living wage,' she said. 'A significant part of LRM is cross-sector collaboration, and (MDOA) has been working with the Maryland Department of Labor and the Governor's WorkForce Development Board on growing jobs in Maryland, including quality jobs in the caregiver sector,' Sigler said. LRM Fact Sheet (Maryland Department of Aging) The public is invited to review Maryland's plan to transform its approach to aging. A town hall will be held from 1 to 3 p.m. March 25 at the Allegany County Fairgrounds, 11490 Moss Ave., in the multi-purpose building. To register, which is free but required as space is limited, visit 'We chose to hold town halls in the eastern, central and Western Maryland geographic regions to ensure access to both rural and urban communities,' Sigler said. Additionally, MDOA will host virtual town halls. 'The LRM plan is posted on for anyone to review and provide feedback,' she said.
