In this way, the suitable cathode material must be at least LiMO2. Therefore, in the case of a maximum transfer of 1 mole of Li, the gram capacity of the layered material is the highest, and it is the first choice for high specific energy batteries.<\/p><p>As a comparison, the spinel material LiMn2O4 is equivalent to transferring only 0.5 mole of lithium (Li0.5MnO2), and the theoretical capacity is low. However, LiFePO4 increases the weight of PO2, so the theoretical specific capacity is also relatively low. It has been known through the previous analysis that the high-voltage LCO and the high-capacity high-nickel ternary in the layered material can achieve an energy density of 500wh\/kg.<\/p><p>However, the safety of these two materials is very poor. The temperature of thermal decomposition and oxygen release will be below 150\u00b0C, and the maximum temperature of thermal runaway can reach above 800\u00b0C. Therefore, although high specific energy can be achieved, high safety cannot be guaranteed, and new material systems need to be developed.<\/p><p>Experts have proposed that multi-electron and light elements are important directions for lithium-ion batteries to achieve high specific energy. Lithium-rich manganese-based materials achieve high capacity through polyatomic transfer, and in fact we can also achieve high capacity by using lighter elements. The most radical of this route is the lithium-air battery, that is, the reaction of Li with O2, but its reversibility is particularly poor.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-108293\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/High-specific-energy-low-cost-high-safety-battery-system.webp\" alt=\"High specific energy, low cost, high safety battery system\" width=\"1000\" height=\"500\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/High-specific-energy-low-cost-high-safety-battery-system.webp 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/High-specific-energy-low-cost-high-safety-battery-system-300x150.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/High-specific-energy-low-cost-high-safety-battery-system-768x384.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/High-specific-energy-low-cost-high-safety-battery-system-600x300.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>In summary, even without considering commercial value, the research and development of 500 wh kg battery has a lot of academic value.

Among them, the Jikrypton 001 Kirin battery version is ready to be delivered, with an energy of 140kwh and a battery life of 1032km. The specific energy of the battery cell is 285wh\/kg, and the energy density of the battery pack is about 205wh\/kg.<\/p><p>It can be seen that the specific energy of the battery cell is less than 300wh\/kg, which already meets the requirements of the battery life of electric vehicles for thousands of miles. For electric vehicles, on the premise of meeting the battery life, cost and safety are more important to consumers. In other words, as long as the basic needs are met, the battery life is enough.<\/p><p>Continuing to increase battery life on this basis will have diminishing marginal effects and will not significantly improve user experience. Even if the 500 wh kg battery guarantees high specific energy and high safety, it is difficult to balance cost, power, cycle life, etc., so the hope of car use is relatively slim.<\/p><p>In addition to automotive use, 3C electronic products are also very important application scenarios of 500 wh kg battery.

Starting from these points, the ternary can be matched.<\/p><h2 id=\"Conclusion\">Conclusion<\/h2><p>The 500 wh kg battery is a must for the advanced battery routes of China, the United States, Japan and other countries, and corresponding progress has been made so far. Although the probability of a 500 wh kg battery being applied in the field of power batteries is very low, a lot of knowledge and experience will be accumulated during the development process.<\/p><p>It can pave the way for the next generation of high specific energy batteries, and can also be used in existing systems to reduce costs and improve safety. The commercialization of 500 wh kg battery can make up for the lack of energy density and help lithium batteries soar in the vast sky.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9daca5d elementor-widget elementor-widget-heading\" data-id=\"9daca5d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-heading-title elementor-size-large\">Related posts<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ab51db8 elementor-grid-3 elementor-grid-tablet-2 elementor-grid-mobile-1 elementor-posts--thumbnail-top elementor-widget elementor-widget-posts\" data-id=\"3ab51db8\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;classic_row_gap&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;34&quot;,&quot;sizes&quot;:[]},&quot;classic_columns&quot;:&quot;3&quot;,&quot;classic_columns_tablet&quot;:&quot;2&quot;,&quot;classic_columns_mobile&quot;:&quot;1&quot;,&quot;classic_row_gap_tablet&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;classic_row_gap_mobile&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]}}\" data-widget_type=\"posts.classic\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-posts-container elementor-posts elementor-posts--skin-classic elementor-grid\" role=\"list\">\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-106847 post type-post status-publish format-standard has-post-thumbnail hentry category-battery-industry category-best-list category-lithium-ion-battery-knowledge tag-battery tag-battery-cell tag-catl tag-lithium-ion-battery\" role=\"listitem\">\n\t\t\t\t<a class=\"elementor-post__thumbnail__link\" href=\"https:\/\/www.takomabattery.com\/fr\/top-5-lifepo4-280ah-cell-in-china\/\" tabindex=\"-1\" >\n\t\t\t<div class=\"elementor-post__thumbnail\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"225\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/Top-5-lifepo4-280ah-cell-in-China-300x225.webp\" class=\"attachment-medium size-medium wp-image-106921\" alt=\"Top 5 lifepo4 280ah cell in China\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/Top-5-lifepo4-280ah-cell-in-China-300x225.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/Top-5-lifepo4-280ah-cell-in-China-768x576.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/Top-5-lifepo4-280ah-cell-in-China-600x450.webp 600w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/06\/Top-5-lifepo4-280ah-cell-in-China.webp 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/div>\n\t\t<\/a>\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<div class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/www.takomabattery.com\/fr\/top-5-lifepo4-280ah-cell-in-china\/\" >\n\t\t\t\tTop 5 lifepo4 280ah cell in China\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-post__meta-data\">\n\t\t\t\t\t<span class=\"elementor-post-date\">\n\t\t\tjuin 8, 2023\t\t<\/span>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-43509 post type-post status-publish format-standard has-post-thumbnail hentry category-battery-industry category-lithium-battery-technology category-lithium-ion-battery-knowledge tag-battery tag-battery-cell tag-lithium-battery tag-lithium-ion-battery\" role=\"listitem\">\n\t\t\t\t<a class=\"elementor-post__thumbnail__link\" href=\"https:\/\/www.takomabattery.com\/fr\/a-comparison-between-20-volt-battery-vs-40-volt-battery-which-is-better\/\" tabindex=\"-1\" >\n\t\t\t<div class=\"elementor-post__thumbnail\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"225\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/05\/A-comparison-between-20-volt-battery-vs-40-volt-battery-which-is-better-300x225.jpg\" class=\"attachment-medium size-medium wp-image-43513\" alt=\"A comparison between 20 volt battery vs 40 volt battery -
