LG Energy Solution, Seoul National University solve gas generation in LMR batteries

LG Energy Solution and Seoul National University said they have addressed a key hurdle to commercialising lithium manganese-rich (LMR) batteries by curbing gas generation in large cells for electric vehicles. The team analysed oxygen redox behaviour during charging and discharging and found that both upper charge voltage and lower discharge voltage affect oxygen recovery. Using redesigned operating and activation conditions, a 40Ah-class LMR large cell retained 92.2 percent of initial energy after 883 cycles.

Is driving a plug-in hybrid in 2026 an in-between choice

Battery electric vehicles retain strengths in efficiency and maintenance convenience, but a driver case suggests a plug-in hybrid can be a more practical choice depending on charging conditions and travel patterns. Cleantechnica on Sept. 5 introduced a family that has used both types. The writer cited EV simplicity and lower maintenance, while noting plug-in hybrids are more complex. Long-distance trips with bikes reduced EV range, prompting a switch to a 2026 Toyota RAV4 plug-in hybrid.

Tesla unveils rare earth-free Cybercab motor; doubts remain over supply chain shift

Tesla said it has fitted Cybercab with a new electric vehicle motor that does not use rare earths. The motor is 18 percent smaller and 25 percent lighter than its existing high-performance drive unit, and is more efficient, according to Electrek. The company has not disclosed the magnet material used. While the change could matter for supply chains amid tighter Chinese export controls on rare-earth processing, broader adoption beyond Cybercab remains uncertain.
