According to foreign media reports, batteries have been integrated into our daily lives. Electric vehicles, flashlights, and remote controls seem to have long been inseparable from batteries in our lives. Fortunately, the battery of the future is developing in a sustainable direction. The editor has compiled five examples of innovative battery technologies in the future for readers to appreciate, as follows: 1. New battery powered by human skin Today, "smartwearables" such as smartwatches, Bluetooth

On the premise of ensuring safety, improving energy density, reducing production costs, and improving product consistency are topics of widespread concern in the power battery industry. The production cost curve is constantly fluctuating, and product consistency is not easy to quantify. To evaluate the technical level of power battery companies, comparing the energy density of cells is the most intuitive method. This article takes the ternary battery as an example, according to the three packaging systems of squ

The new energy vehicle market has achieved unprecedented development. Correspondingly, the new energy vehicle technology has also performed well. From the perspective of the entire electric vehicle system, the overall driving range has been improved, and the energy consumption per 100 kilometers is also much lower than in the past. In addition, great progress has been made in many aspects such as battery safety, energy recovery, and lightweight. So, in the past year, which industrial technologies have attracted our

Recently, the research group of Professor Xu Maowen from the Department of Materials and Energy of Southwest University has made important progress in the design and development of high-performance lithium-sulfur batteries. Relevant research results were published in the international energy journal Advanced Energy Materials (Advanced Energy Materials) under the title of "Double-ShelledNiO-NiCo2O4HeterostructureCarbonHollowNanocagesasAnEfficientSulfurHostforAdvancedLithium-SulfurBatteries", with an impact

According to the "Nihon Keizai Shimbun" report, the Japanese government will join hands with private enterprises to promote the development of a new generation of pure electric vehicle (EV) batteries. Starting in May, Japan's Ministry of Economy, Trade and Industry will cooperate with Toyota, Asahi Kasei, Panasonic and other automotive, materials, and electronic machinery companies to promote the development of high-efficiency all-solid-state batteries. At present, Japan is losing market share to Chin

Recently, according to South Korean media reports, the research team of Samsung Electronics General Technology Institute has successfully developed a new battery material "graphene ball", which is 45% higher than the charging capacity of existing lithium-ion batteries, and the charging speed is increased by more than 5 times. The researchers found that after adding silica to the high-strength, high-conductivity graphene material, graphene can be synthesized in large quantities, and the synthesized grap

As a new type of nanomaterial with the thinnest, hardest, and the strongest electrical and thermal conductivity ever discovered, graphene is known as "black gold" and "the king of new materials". Scientists even predict that graphene will become a revolutionary material in the 21st century. "Black Technology". Since it was first artificially produced 12 years ago, it has become a global goal to bring graphene, which has broad application prospects in the fields of electronic informa

Recently, the Ministry of Industry and Information Technology released the "Catalogue of Recommended Models for the Promotion and Application of New Energy Vehicles", in which no ternary electric commercial buses have been found, which means that the models that have not entered the "Catalogue" will not be able to enjoy government subsidies and purchase tax-exempt (10%) vehicles. Preferential policies. A "suspend order" for ternary lithium batteries has thrown a "bomb" into C

According to foreign media reports, on May 30, local time, Panasonic said that it will develop cobalt-free batteries for automobiles in the near future. As an important battery component for electric vehicles, the price of cobalt materials has also soared with the development of electric vehicles. Kenji Tamura, head of Panasonic's automotive battery business, said in a meeting with analysts, "We have significantly reduced the use of cobalt and hope to achieve cobalt-free batteries in the near future, an
