Battery Development

Chinese battery manufacturer CATL expects to begin producing sodium-ion batteries for electric vehicles in significant quantities this year. According to production chief Ni Jun, this battery technology is expected to power approximately 10,000 to 20,000 vehicles by 2026. However, CATL CEO Robin Zeng is tempering expectations for solid-state batteries. He states that widespread mass production is not yet on the horizon. Sodium-ion batteries set to debut in vehicles soon CATL has been working on sodium-ion batteries since 2016. To date, the company has invested nearly 10 billion yuan (just under 1.5 billion U.S. dollars) in their development, a figure expected to reach 15 billion yuan by the end of 2025. In April 2025, CATL launched the Naxtra brand for this purpose. The cells are expected to achieve an energy density of up to 175 Wh/kg. According to the company, this is roughly equivalent to standard LFP batteries. A production vehicle developed in partnership with Changan Automobile is set to be released in mid-2026. CATL states that the range will be up to 400 kilometers. Once the supply chain matures, CATL believes a range of 500 to 600 kilometers will be possible. CATL cites cost savings and improved performance in cold weather as the main advantages. Even at minus 40 degrees Celsius, capacity retention is expected to remain above 90 percent. CATL is also expanding its presence in the stationary storage sector. The Tener Sodium system is scheduled to begin shipping in China in September. Global deliveries are planned for June 2027. Solid-state technology remains development territory for now CATL is taking a much more cautious stance on solid-state batteries. Zeng rated the current state of the technology as level four out of nine. Level nine represents mass production. Zeng noted that technical progress, reliability, safety, supply capability, and commercial acceptance are all crucial factors. Previous statements indicated that CATL aims to reach levels seven or eight by 2027. This would enable small-scale production runs. However, high costs and unresolved production issues remain hurdles. Zeng had previously stated that producing in the millions is unlikely before 2030.

According to a Reuters report, General Motors may change its plans for the batteries in its future electric vehicles.  The company’s head of batteries, Kurt Kelty, revealed that the U.S. automaker is considering excluding LFP cells from its EV portfolio. Previously, GM had announced plans to develop lithium iron phosphate (LFP) batteries for future electric vehicle models. Production was scheduled to begin in late 2027 at a jointly operated plant in Tennessee. However, GM is now shifting its focus toward lithium-manganese-rich (LMR) batteries. The company apparently views this cell chemistry as the more important technology for higher production volumes. According to GM, LMR cells in the U.S. are expected to cost roughly the same as LFP cells but have a higher energy density. The Tennessee plant is set to begin producing LFP cells this month. However, these are intended for stationary energy storage, not electric vehicles. Strategy deviates from market trend Avoiding the use of LFP cells in electric vehicles would set GM apart from many competitors, who use LFP cells to reduce costs and offer more affordable electric vehicles. Several manufacturers use LFP cells to reduce costs and offer more affordable electric vehicles. These include Tesla, Rivian, and Ford. Chinese manufacturers adopted the technology on a large scale early on. LFP batteries are considered cheaper, more robust, and safer than many nickel-rich cell chemistries. However, their lower energy density can lead to shorter ranges. GM has used more powerful nickel-rich batteries in more than a dozen U.S. electric models so far. The new Chevrolet Bolt, on the other hand, is expected to use LFP cells from the Chinese company CATL.

General Motors and Peak Energy plan to develop sodium-ion battery cells for stationary grid storage. This initiative is based on a strategic partnership that includes an investment by GM Ventures in Peak Energy. The goal is to deploy the cells in large-scale energy storage systems. The technology is expected to be ready for mass production in 2028 at the earliest. As part of the collaboration, GM will develop the sodium-ion cell in its Michigan battery laboratories. The company will also retain exclusive manufacturing rights. Peak Energy will then integrate the cells into its own energy storage systems. Passively Cooled Storage as a Cost Advantage According to Peak Energy, the company is focusing on passively cooled storage systems. These systems are designed to operate without the energy-intensive active cooling common in many lithium iron phosphate systems. Peak Energy claims its sodium-ion systems could reduce storage costs by 20 percent compared to conventional systems. GM Seeks Additional Uses for Battery Investments For GM, this move comes during a period of weaker electric vehicle sales in the U.S. The NYT reports that GM and other manufacturers have scaled back production of electric cars. Reasons for this include the expiration of tax incentives and heavy losses from previous investments in electric cars. Stationary storage systems could help automakers leverage their existing battery expertise more broadly. Tesla has been selling such systems since 2015, and Ford is planning large-scale battery storage projects as well.
