Core Insights - QuantumScape has signed a manufacturing agreement with Corning to scale production of its solid-state lithium-metal battery technology, which has led to a 14% increase in its stock price this week [1][3][4] Group 1: Company Developments - QuantumScape showcased its solid-state battery technology for the first time at a mobility summit in Germany, featuring a Ducati racing motorcycle powered by its battery cells [3] - The partnership with Corning is expected to enhance the development and commercialization of QuantumScape's ceramic battery components, which aim to provide safer and more efficient batteries for electric vehicles [4][5] Group 2: Market Reaction - Following the announcement of the manufacturing agreement, investor confidence in QuantumScape has increased, resulting in a notable rise in stock price [1][5] - The company has been viewed as a "story stock," with previous hesitance from investors due to the lack of a clear commercialization plan until now [4]

Core Insights - General Motors (GM) has introduced a new battery chemistry called lithium-manganese-rich (LMR), which aims to reduce costs while providing a driving range of over 400 miles in their trucks [1][3] - The LMR technology will significantly decrease the reliance on nickel and cobalt, which are critical minerals not readily available in the U.S. [2] Cost and Range Analysis - The Chevrolet Silverado EV currently uses nickel-manganese-cobalt (NMC) cells, achieving a range of 492 miles but starting at a price of over $73,000. A version with lithium-iron-phosphate (LFP) cells will reduce the price by $6,000 but lower the range to 350 miles. LMR technology aims to maintain price reductions while minimizing range loss [3] - The new LMR cells will contain 0-2% cobalt, 30-40% nickel, and 60-70% manganese, making them cheaper than current NMC cells, which contain up to 10% cobalt and 80% nickel [4] Manufacturing and Design Innovations - LMR battery packs will utilize prismatic cells instead of pouch cells, allowing for a battery pack design with over 50% fewer parts, leading to significant cost savings [7] - GM has invested billions in battery manufacturing through its joint venture with LG Energy Solution, focusing on LMR technology for the past decade [9][10] Market Strategy and Future Plans - GM plans to integrate LMR technology across its electric vehicle lineup, positioning LFP for entry-level vehicles and NMC for high-range applications [8] - The company has produced approximately 300 large-format cells, equating to around 1.5 million miles of testing, with a target to scale production by 2028 [11][12]
