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.

Sodium-ion batteries seen as next contender in grid ESS market, with 20 percent share projected by 2030

Sodium-ion batteries are emerging as a next alternative in the grid energy storage system market, helped by lower raw material costs, performance in low temperatures and reduced cooling needs, Cleantechnica reported. Morgan Stanley Research estimates their installed-base share will reach 2 percent in 2027, 20 percent in 2030 and 37 percent in 2035. U.S. companies including ESS, Peak Energy and Unigrid are preparing products for grid and residential storage.

Ecopro BM begins Hungary plant line conversion

Ecopro BM has begun work to convert an existing NCA production line at its Hungary plant into a line that can also produce NCM, it said on Sunday. The move aims to supply high-nickel cathode materials for premium electric vehicles in Europe from the fourth quarter of next year. The conversion is expected to cost about 40 billion won. The Hungary plant began commercial operations in the first half of this year and is running at 54,000 tons of annual capacity.
