LG Energy Solution, in collaboration with Seoul National University, has identified a critical factor in lithium manganese-rich (LMR) battery degradation: voltage limits during charging and discharging. This breakthrough research pinpoints operating conditions that effectively suppress gas generation, a major hurdle for integrating LMR chemistry into larger, high-capacity EV battery packs. The findings pave the way for more stable and efficient next-generation electric vehicle batteries.
A collaborative effort between LG Energy Solution and Seoul National University has significantly improved the longevity of lithium-manganese-rich (LMR) battery cells. By optimizing charging and discharging protocols, researchers maintained 92% capacity after 883 cycles, addressing a key hurdle for this promising, cost-effective battery chemistry.
Japanese chemical giant Asahi Kasei has unveiled a novel lithium pre-doping technology aimed at enhancing the performance of silicon-rich lithium-ion batteries. By integrating lithium carbonate into the cathode, the innovation significantly mitigates the permanent capacity loss typically experienced during the cell's initial charge-discharge cycle, a critical step for improving EV range and durability.
New research indicates that a specific manufacturing flaw in high-nickel, manganese-containing EV battery cathodes could lead to premature battery degradation. This discovery suggests that while these chemistries aim to boost range and reduce reliance on expensive materials, improper handling of precursors during production might compromise their long-term durability.
The type of battery powering an electric vehicle significantly impacts its performance, cost, and longevity. While all EV batteries are fundamentally lithium-ion, their cathode chemistry, specifically whether it's Lithium Iron Phosphate (LFP) or Nickel Manganese Cobalt (NMC), offers distinct advantages and trade-offs. Understanding these differences can help consumers make informed decisions when purchasing an EV.
A new UK government-backed initiative aims to advance lithium manganese iron phosphate (LMFP) battery technology for both electric vehicles and defense applications. Integrals Power will provide the critical cathode active material for this £2-million, 30-month development program, led by the Denchi Group.
Researchers at the U.S. Department of Energy's Argonne National Laboratory have discovered that a nanometer-thin magnesium oxide coating can significantly improve the stability of sulfide-based solid-state electrolytes. This breakthrough could be crucial for advancing next-generation solid-state batteries, which promise greater energy density and safety for electric vehicles.

The electric bicycle industry is keenly eyeing sodium-ion batteries as a potential game-changer. These next-generation power cells promise substantial cost reductions, improved safety profiles, and a decreased reliance on scarce materials such as lithium, cobalt, and nickel, addressing key pain points in current battery technology.
The electric vehicle industry is increasingly exploring sodium-ion battery technology as a compelling alternative to traditional lithium-ion cells. These batteries, which avoid critical materials like lithium, nickel, and cobalt, offer a promising pathway to reduce costs and dependence on scarce resources, accelerating the adoption of more affordable EVs globally.
Integrals Power, a UK-based company, has announced successful external validation of its lithium iron phosphate (LFP) cathode active material. Cell tests at the University of St Andrews confirmed a specific capacity exceeding 153 mAh/g, positioning their UK-produced LFP favorably against existing Chinese market leaders. This advancement could bolster the Western supply chain for crucial EV battery components.
The chairman of CATL, the world's leading EV battery manufacturer, has tempered expectations for solid-state batteries, stating the technology is currently only at "level four" on a nine-step readiness scale. He predicts that widespread adoption and commercial viability for solid-state batteries are not expected until at least 2030, suggesting the technology is still far from ready for mass production.
GM Energy is enhancing its offerings with new vehicle-to-grid (V2G) support, allowing compatible GM EVs to send power back to the home or grid. Alongside this, the company announced advancements in energy storage battery chemistry, aiming for more efficient and sustainable power solutions.
