General Motors and LG Energy have announced plans to use lithium manganese-rich (LMR) prismatic battery cells in electric trucks and full-size SUVs. The automaker intends to be the first to use LMR batteries and production is slated to begin by 2028.

GM says LMR batteries are a breakthrough as traditional battery cathodes require nickel, manganese, and expensive cobalt. This drives up prices and makes EVs expensive.

LMR batteries seek to address this by using a “higher proportion of more affordable manganese.” They also promise to deliver a “greater capacity and energy density.”

The companies didn’t go into many specifics, but said their new LMR prismatic battery cell has a  33% higher energy density than the best-performing lithium iron phosphate (LFP) cells, despite having a comparable cost.

So what does this all mean? We can expect an electric truck that delivers more than 400 miles (644 km) of range as well as “significant battery pack cost savings compared to today’s high-nickel pack.” That would be a welcome development as the 2025 Chevrolet Silverado EV LT Extended Range starts at $75,195 and has an EPA-estimated range of up to 408 miles (657 km).

GM’s director of advanced battery cell engineering said the batteries are the result of a decade of development. Kushal Narayanaswamy went on to say GM’s current crop of electric trucks and SUVs use NMCA batteries and these have a composition that is roughly 85% nickel, 10% manganese, and 5% cobalt. LMR batteries are vastly different as they’re about 65% manganese, 35% nickel, and use “virtually no cobalt.” In effect, they use more of the cheaper materials and less of the expensive ones.

The Hyundai Motor Group stormed the Seoul Mobility Show with an impressive array of concepts and production models. Besides the redesigned Nexo and facelifted Ioniq 6, Genesis brought a beautiful G90 coupe and convertible.

That brings us to Kia, which introduced a couple of PV5 Spielraum concepts. Named after the German word for “play space,” the vans are built for digital nomads.

The first is the Spielraum Studio concept, and it’s essentially a store on wheels. The rear doors open to reveal shelves that can display products, while the cargo area has a clothes rack as well as clear cases holding shoes.

The oddities continue inside with a smart mirror, coffee machine, and what appears to be a refrigerator. They’re joined by a round chair as well as an LG Styler, which is billed as a “clothing care solution designed for garment caring, focusing on sanitization and deodorization through TrueSteam technology.”

Since AI is the latest buzzword, artificial intelligence has been incorporated into the concept to monitor your schedule and calculate the remaining travel time to your destination. It also recommends settings for the LG appliances housed within.

The Spielraum Glow Cabin concept goes in a different direction thanks to a lounge-like interior with a wraparound sofa and covered walls. Kia says this variant was “designed to cater to the growing demand for car picnic experiences,” so it features a refrigerator, oven, and wine cellar. We can also see what appears to be a cooktop and storage compartments.

This would make for an interesting tailgating vehicle, and Kia noted the appliances are covered by color-changing MoodUP panels. Users can adjust their look via the LG ThinQ app.

It’s no coincidence that Kia and LG teamed up for the concepts as the two firms have decided to “collaborate on the implementation of mobility space solutions based on PBV (Platform Beyond Vehicle) technology.” The companies didn’t go into many specifics, but we can expect to find LG’s AI and appliances in PBV vans.

The firms said the tie-up will enable owners to transform their vehicles into a personalized office, studio, or lounge. We can expect to learn more in the future as the partnership is slated to bear fruit in the second half of 2026.
