As fuel cell electric passenger vehicles enter the market, many consumers believe that fuel cells are only used in cars. In fact, fuel cell electric passenger vehicles are probably one of the toughest markets to break right now, and fuel cells can scale to meet many different energy conversion or power needs. Fuel cells are proving to be a versatile technology from primary stationary power and cogeneration applications, to powering cell phones and laptops.(Lithium - Ion Battery Equipment) There are already three

Recently, researchers at Linköping University in Sweden have successfully developed a new type of fuel cell using lignin from trees as a raw material. Unlike batteries that use small molecules such as methanol and ethanol as fuel, this process does not generate carbon dioxide, not only is the raw material green and environmentally friendly, but also the product achieves zero carbon emissions. Lignin is an important structural material for plants and algae. It is common in bark or wood and is one of the by-p

Phased progress has been made in energy density solid-state lithium batteries. In terms of industrialization demonstration of high-energy-density, high-safety deep-sea solid-state lithium batteries, the company has conquered the key core technologies of deep-sea long-endurance power supplies, and has achieved the 11,000-meter pressure chamber test. And the whole deep-sea demonstration application, boosting the national deep-sea power supply to a new height.（Lithium - Ion Battery Equipment） The fire accidents of

The University of Bologna in Italy released news that after 8 years of hard work, researchers at the school have developed a new semi-solid oxygen flow lithium battery NESSOX. With an energy density of up to 1 MWh/ton, it can be recharged in minutes by replacing the liquid electrolyte inside the battery, just like a car "refueling". The battery uses a new type of liquid electrolyte, which can effectively inhibit the formation of substances that cause battery failure and maintain stable battery performance

Not long ago, Zhao Zhongwei, deputy dean of the School of Metallurgy and Environment of Central South University, and his team "packed" a container full of "black technology" equipment, and "tugged a box with a port" from Changsha, Hunan to "Golmud," Qinghai. A huge "black box" container with several water pipes that can "turn decay into magic". The local salt lake brine with high "magnesium-to-lithium ratio" entering the "black box"

EnergyTrend, a new energy research brand under TrendForce, said in a report that, under the influence of China's new energy policy, the demand for power batteries continued to grow, resulting in a shortage of cylindrical lithium batteries for IT. With the market adjustment, the current tight supply situation has been gradually eased. The latest lithium battery quotation shows that the price increase of cylindrical lithium battery in the second quarter is about 1~4%. With the expansion of production capacity,

The lithium battery protection board is the charge and discharge protection for the series-connected lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), and realize the equal charge of the individual cells of the battery pack. , effectively improving the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperatur

The pursuit of zero-carbon emission vehicles in advanced countries around the world is becoming more and more popular, and the demand for new energy vehicle specifications has become increasingly clear. However, the current sluggish development of lithium battery technology restricts the cruising range and safety, making the upgrade of new energy vehicles slow. Recently The shocking battery fire accident of new energy vehicles has occurred again and again, forcing BMW, Toyota and other international car manufacture

On September 11, Germany's "Automobile Weekly" reported that Volkswagen announced a large-scale electric vehicle development plan "RoadmapE". By 2030, all Volkswagen models will have electric versions, investing 50 billion euros in electric vehicle batteries and 20 billion euros in electric vehicles. car. It is not new for OEMs to invest in batteries, and Volkswagen CEO Murren also said that they are already planning the next generation of electric vehicle batteries, solid-state batteries
