https://interestingengineering.com/energy/ustc-lithium-hydrogen-battery China’s new hydrogen EV battery hits 2825 Wh/kg energy density with 99.7% efficiency USTC’s latest innovation introduces a safer, more sustainable future for battery-powered systems. Updated: Feb 14, 2025 08:42 AM EST Stock photo: Hydrogen fuel cell concept. Anew study from the University of Science and Technology of China (USTC) can potentially elevate renewable grid energy storage and electric vehicles to unprecedented heights. It involves a new type of chemical battery system that utilizes hydrogen gas as the anode instead of the conventional lithium derivatives. The research team published their findings in the Angewandte Chemie International Edition. Over the past years, hydrogen (H2) has gained attention as a stable and cost-effective renewable energy carrier due to its favorable electrochemical properties. However, current hydrogen-based batteries primarily utilize H2 as a cathode. This restricts their voltage range to 0.8–1.4 V and limits their energy storage capacity. The batteries can only operate within a limited voltage window, which caps how much energy they can store and deliver. Imagine a world where electric vehicles charge faster and last longer; USTC’s new Li-H battery could make this a reality The USTC research team went down an innovative path to improve battery performance and overcome this limit. They proposed utilizing H2 as the anode to enhance energy density and working voltage significantly. The team engineered a prototype battery system with a configuration that allows efficient lithium-ion transport while minimizing undesired chemical interactions. Designated as the Li-H battery, this prototype includes a lithium metal anode, a platinum-coated gas diffusion layer serving as the hydrogen cathode, and a solid electrolyte (Li1.3Al0.3Ti1.7(PO4)3, or LATP). Through rigorous testing, this new model displayed a staggering theoretical energy density of 2825 watt-hours per kilogram (Wh/kg), with a steady operational voltage of around three volts. Moreover, the battery exhibited an exceptional round-trip efficiency (RTE: a measure of energy delivered versus energy used to charge the battery) measured at a staggering 99.7%, signifying minimal energy dissipation during charge and discharge cycles, with remarkable long-term operational stability. To make this solution even more cost-effective and safe while enhancing manufacturability, the team developed an anode-free Li-H battery variant that eliminates the need for pre-installed lithium metal. Instead, the battery facilitates the deposition of lithium sourced from lithium salts (specifically LiH2PO4 and LiOH) during the charging cycle. This new and improved version retains the advantages of the aforementioned Li-H battery while providing additional benefits. It enables efficient lithium plating and stripping with an impressive Coulombic efficiency (CE: is the ratio of the input and output charges) of 98.5%. It also operates stably even at low hydrogen concentrations, reducing reliance on high-pressure H₂ storage. Computational modeling, such as Density Functional Theory (DFT is a computational quantum mechanical modeling) simulations, were also performed to get insights into how lithium and hydrogen ions move within the battery’s electrolyte. This step in Li-H battery innovation provides new opportunities for advanced energy storage solutions, and the USTC’s research team has opened the doors for future explorations into lithium-hydrogen battery tech applications. The impact of this finding can transform the performance and efficiency of renewable energy systems, long-range electric transportation, and next-generation aviation. The Li-H system provides improved energy density and efficiency compared to regular nickel-hydrogen batteries. It is a strong candidate for the next-gen power storage systems of an increasingly electrified world moving towards decarbonization. The anode-free version has proven effective in establishing a pathway toward more affordable and scalable hydrogen-based batteries.
An EV can now be charged in a mere 5 minutes. A combination of advancements in battery and charging technology. BYD unveils new super-charging EV tech, to build charging network in China https://finance.yahoo.com/news/chinas-byd-unveils-faster-charging-114700761.html BEIJING (Reuters) -BYD on Monday unveiled a new platform for electric vehicles (EVs) that it said could charge EVs as quickly as it takes to pump gas and announced for the first time that it would build a charging network across China. The so-called "super e-platform" will be capable of peak charging speeds of 1,000 kilowatts (kW), enabling cars that use it to travel 400 km (249 miles) on a 5-minute charge, founder Wang Chuanfu said at an event livestreamed from the company's Shenzhen headquarters. Charging speeds of 1,000 kW would be twice as fast as Tesla's superchargers whose latest version offers up to 500 kw charging speeds. Fast-charging technology has been key to increasing EV adoption as it is seen to help assure EV drivers' concerns over being able to charge their cars quickly. "In order to completely solve our user's charging anxiety, we have been pursuing a goal to make the charging time of electric vehicles as short as the refuelling time of petrol vehicles," Wang said. "This is the first time in the industry that the unit of megawatt (charge) has been achieved on charging power," he said. The new charging architecture will be initially available in two new EVs - Han L sedan and Tang L SUV priced from 270,000 yuan ($37,328.91) and BYD said it would build over 4,000 ultra-fast charging piles, or units, across China to match the new platform. The company didn't specify the time frame or how much it would invest in building such facilities. To date, BYD owners have largely relied on other automakers' charging facilities or public charging poles run by third-party operators to charge their vehicles. Tesla has offered its superchargers in China since 2014 and BYD's smaller Chinese peers such as Nio, Li Auto, Xpeng and Zeekr have also been investing extensively and building charging facilities for years. BYD mostly relies on plug-in hybrids for its sales, which hit 4.2 million units last year. It has targeted selling 5-6 million units this year.

Round Trip efficiency for the module is over 99% compared to 90% for Li and 30-85% for Hydrogen with energy recovery. f. Charge time for supercapacitors is minutes compared to hours for Li and Hydrogen g. Discharge rates up to 5 times Li and Hydrogen h. The temperature range for the supercapacitor batteries is an impressive -30 to +70 degrees with no cooling required making them extremely adaptable to all environments i. Pure supercapacitor Batteries are 100% static electricity storage and therefore do not require exotic material or mined resources and are manufactured using synthetic graphene which makes them a significant decarbonising technology Low pressure Hydrogen Low pressure Hydrogen (LPH) storage technology is simple and cost competitive with Li Ion capex solutions with improved safety and lower operational cost. j. The low pressure (LPH) storage is consistent with safe Metal Hydride solutions, with no thermal runaway fire risk k. LPH is being implemented on our Telstra contract and will provide Telstra with over 50% cost saving compared to the previous Hydrogen technology l. LPH is simple and has no requirement for thermal management which is required for Metal some Hydride storage. m. LPH and Metal Hydride solutions have virtually zero self-discharge making the solution well placed for large seasonal shift of energy compared to other technologies. Supercapacitor Batteries and LP Hydrogen storage solutions both have their place in providing storage and where Supercapacitors will replace Li Ion solutions, Hydrogen is still well placed to provide seasonal energy storage shift due to virtually nil self-discharge rate. H2G is also moving to supercapacitor batteries Level 12, 680 George Street Sydney NSW 2000 ABN: 51 000 689 725 cosec@companymatters.com.au www.greenHy2.com.au instead of Li Ion for the startup and balancing requirements in our H2 systems.
