Geely Holding has announced plans to begin pilot deployment of solid-state battery packs in vehicles from its brands in 2027. According to the company, the most advanced version of the battery will deliver an energy density of up to 500 Wh/kg, which could potentially allow electric vehicles to travel more than 1,000 km on a single charge. As early as 2026, Geely has already begun testing the technology under real-world conditions, and after validation is completed in 2027, the batteries are planned to be installed in limited batches on vehicles from the holding's ecosystem — which includes Geely, Zeekr, Lynk & Co, Volvo, Polestar, Lotus, Smart, Proton, Farizon, and other brands. The company has not yet specified which exact models will be the first to receive the new batteries. ### What This Means for Range According to Geely's estimates, electric vehicles equipped with the new batteries will approach diesel-powered cars in terms of driving range. The stated target is more than 1,000 km on a single charge. The increased specific energy capacity theoretically makes such a range achievable without a proportional increase in battery mass, which is a key advantage of the solid-state architecture over conventional lithium-ion solutions. ### Comparison with Current Golden Brick Cells Geely is developing several variants of solid-state batteries with different specific energy capacities. The flagship version is rated at 500 Wh/kg. For comparison, the company's liquid-electrolyte Golden Brick cells have an energy density of about 250 Wh/kg at the cell level. Thus, the claimed gain is roughly twofold, confirming the scale of the technological leap that Geely intends to achieve within the next two years. ### Partnership with Dow Chemical One of Geely's partners in materials development is the American company Dow Chemical. The company previously developed a special adhesive for solid-state battery cells that maintains stability at temperatures ranging from -40 to +120 °C. This is critical for ensuring battery reliability across a wide range of operating climate conditions, from severe frosts to hot regions. ### Realistic Mass-Production Timelines That said, the mass appearance of fully solid-state batteries in electric vehicles in 2027 should not be expected. CATL previously rated its own technology at only the fourth level on a nine-point technology readiness scale (TRL), although the company expects to move on to full-scale prototypes and subsequent certification. In other words, 2027 will most likely be a stage of limited testing and pilot deployment, rather than full-scale mass production. BYD has also announced similar plans for 2027, indicating an industry-wide shift toward solid-state solutions. ## 🔍 Fact-Check Verification - [Geely EVs to Approach Diesel Cars in Range: As Early as 2027, Geely Will Start Installing 500 Wh/kg Solid-State Batteries in Its Vehicles](https://www.ixbt.com/news/2026/08/19/429155-elektromobili-geely-pribliziatsia-k-dizelnym-masinam-po-zapasu-xoda-uze-v-2027-godu-geely-nacnet-ustanavlivat-v-svoi-avto-tverdotelnye-batarei-s-plotnostiu-energii-500-vtckg.html) - Подтверждает 500 Вт·ч/кг, 2027 год, запас хода >1000 км и пилотный характер внедрения. - [Geely Announced a 2027 Project for EVs with 500 Wh/kg Solid-State Batteries](https://overclockers.ru/blog/kosmos_news/show/262123/Geely-anonsirovala-na-2027-god-proekt-elektromobilej-s-tverdotel-nymi-batareyami-emkost-ju-500-Vt-ch-kg) - Совпадает по срокам 2027 г. и значению 500 Вт·ч/кг. - [A Million Kilometers Ahead: Geely, Volvo, and Zeekr EVs to Get a Breakthrough Battery](https://focus.ua/auto/765093-tverdotelnaya-batareya-geely-obespechit-elektromobilyam-zapas-hoda-v-1000-km) - Подтверждает запас хода ~1000 км и участие брендов Volvo, Zeekr из экосистемы. - [BYD Plans to Switch to Solid-State Batteries by 2027](https://overclockers.ru/blog/letsplay/show/208735/BYD-planiruet-perejti-na-tverdotel-nye-batarei-k-2027-godu) - Совпадает по срокам 2027 г. и значению 500 Вт·ч/кг. ## ❓ FAQ ### Q: When will Geely start installing solid-state batteries? **A:** Pilot deployment is scheduled for 2027, after validation is completed; real-world testing is already underway in 2026. ### Q: What is the energy density of the new batteries? **A:** The flagship solid-state battery version is rated at up to 500 Wh/kg, twice that of the current Golden Brick cells (~250 Wh/kg). ### Q: What range is promised? **A:** More than 1,000 km on a single charge, bringing electric vehicles close to diesel cars in driving range. ### Q: Will there be mass production in 2027? **A:** No, only limited pilot deployment is expected; by analogy with CATL, the technology is still at an early readiness level (TRL 4 out of 9). ### Q: Who is Geely's materials partner? **A:** The American company Dow Chemical, which developed an adhesive for solid-state cells stable across -40 to +120 °C.
