Chinese EV giant BYD Co. Ltd. (OTC:BYDDY) (OTC:BYDDF) has reached breakthroughs in its Sodium-ion, as well as solid-state battery pursuits.<h2>10,000 Charging Cycles</h2>The automaker shared in an investor note that its sodium-ion batteries would be capable of 10,000 cycles, CnEVPost reported on Sunday. The company also shared that its sodium-ion battery research platform had reached its third generation, the report suggests.Typically, current batteries are capable of anywhere between 1,500 and 3,000 cycles. An enhanced cycle range for the EV battery could significantly increase its lifespan, helping the battery last for years.For context, a typical Tesla Inc. (NASDAQ:TSLA) battery lasts for about 300,000 to 500,000 miles, which would translate to at least 1,500 charge cycles, according to UK-based used car platform Cinch. BYD, on the other hand, says its current Blade LFP (Lithium Iron Phosphate) batteries can last for 5,000 cycles.As far as the solid-state battery project goes, BYD shared that its sulfide solid-state battery could be in small-scale production by 2027, promising enhanced lifespan and faster charging times for the batteries.<h2>BYD's Stock Sell-Off, Ford Partnership?</h2>The news comes as BYD's Hong Kong-listed shares experienced a decline recently, fueled by the company's below-average sales in January in the Chinese domestic market. The automaker's sales fell 30% last month, selling 210,051 units, which was a 50% decline from its December 2025 performance.BYD was also reportedly in talks with Ford Motor Co. (NYSE:F) as the latter mulled procuring batteries for its Hybrid vehicles as demand for EVs slows in the U.S. market. Ford's hybrid vehicle sales rose 18% YoY in the fourth quarter as it sold about 55,000 vehicles.<h2>Tesla's Battery Chemistry Breakthrough</h2>Meanwhile, Tesla also shared that it recorded a major battery chemistry breakthrough, outlining its dry electrode process, which the automaker says would help quell significant risk to the environment and human health posed by a wet electrode process, which uses wet solvents like N-Methyl-2-pyrrolidone (NMP).The breakthrough also means that Tesla can add enhanced energy density to its battery through the dry electrode process, while also simplifying the manufacturing process of the battery.Check out more of Benzinga’s Future Of Mobility coverage by following this link.Photo courtesy: Tada Images / Shutterstock.com

BYD has announced advancements in its Sodium-ion and solid-state battery technologies, promising a lifespan of 10,000 charging cycles. The company aims for small-scale production of its solid-state batteries by 2027, which will offer faster charging times. Despite these innovations, BYD's stock has recently declined due to a 30% drop in sales in January. Additionally, BYD is reportedly in discussions with Ford for battery supply as EV demand slows in the U.S. market. Meanwhile, Tesla has achieved a breakthrough in battery chemistry with its dry electrode process, enhancing energy density and manufacturing efficiency.

- BYD Co. Ltd. has achieved advancements in sodium-ion batteries, capable of 10,000 charging cycles, and is progressing in solid-state battery production expected by 2027.  
- The company reported a significant sales decline of 30% in January 2026, amidst discussions with Ford for battery procurement for hybrid vehicles.  
- Tesla also announced a breakthrough in battery chemistry through a dry electrode process, enhancing energy density and production efficiency.
