However, to achieve mass marketization, it is crucial for BEVs to achieve a range of more than 500 kilometers, and the cost of the car is less than 40,000 $.<\/p><p>Unfortunately, lithium-ion batteries based on graphite anodes and lithium transition metal oxide anodes are almost impossible to achieve such high energy densities.<\/p><h2 id=\"Presentation_of_results\">Presentation of results<\/h2><p>Recently, an article entitled &#8220;Opportunities and Challenges of High-Energy Lithium Metal Batteries for Electric Vehicle Applications&#8221; on ACS Energy Lett.<\/p><p>In terms of energy density and cost, lithium metal battery has a huge advantage over existing lithium-ion battery, providing huge opportunities for long-range and low-cost electric vehicles. In this paper, the researchers discuss the requirements and challenges of high-energy density lithium metal battery in future electric vehicle battery packs and system applications, and highlight the latest advances in these areas.<\/p><h2 id=\"Illustrated_reading\">Illustrated reading<\/h2><p>In order for electric vehicles to successfully replace traditional internal combustion engine vehicles, driving distance and price are the most important factors to consider, and another important factor is battery life. As lithium metal battery energy density increases, more energy can be stored in battery packs of the same size or weight. Due to the longer drive range per charge, the cycle life requirements for lithium metal battery may be reduced. For EV applications, lithium metal battery requires a cycle life of at least 500-1000 cycles.<\/p><p>The long cycle life of LIB is the formation of a stable solid electrolyte intermediate phase (SEI) layer on the graphite anode, which prevents the electrolyte from further decomposing and spalling during cycling. However, unlike graphite, the lithium metal anode exhibits large volume and morphological variations during repeated plating or stripping processes.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-46057 size-full\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Three-key-parameters-for-bag-batteries.jpg\" alt=\"Three key parameters for bag batteries\" width=\"1000\" height=\"442\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Three-key-parameters-for-bag-batteries.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Three-key-parameters-for-bag-batteries-300x133.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Three-key-parameters-for-bag-batteries-768x339.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Three-key-parameters-for-bag-batteries-600x265.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">Three key parameters for bag batteries<\/span><\/p><h4 id=\"Operating_temperature_range\">Operating temperature range<\/h4><p>Temperature has a great influence on lithium metal battery, and the electrochemical reaction kinetics and ion conductivity will vary with temperature changes. In extreme conditions, safety issues such as fires, gas releases, and explosions can be caused.<\/p><p><strong>Microtherm.<\/strong> It has been found that the performance of the battery will decay rapidly below 0 \u00b0C. This attenuation is thought to be due to lower ion conductivity, higher charge transfer resistance, and lower Li ion diffusion at low temperatures. At low temperatures, lithium plating occurs on the anode electrode.<\/p><p><strong>High temperature.<\/strong> When operating at high temperatures, lithium-ion batteries age quickly, reflected in the rapid decline in battery capacity and performance. Side reactions between the cathode and the electrolyte and changes in the inactive electrode assembly are critical for aging degradation at high temperatures.<\/p><h4 id=\"Quick_discharge_and_charging\">Quick discharge and charging<\/h4><p>The high magnification capability of the battery is critical to the performance of an electric vehicle. For any EV, regenerative braking or &#8220;refueling&#8221; of a fast pulse discharge and continuous charging energy storage system is required. One challenge in the high-speed operation of lithium metal battery is the generation of heat, which increases the battery temperature, thereby accelerating the aging of the battery. On the other hand, the morphology and recyclability of the lithium anode depends on the current density of stripping and plating.<\/p><p><strong>Battery volume changes.<\/strong> First, the matrix-free deposition and dissolution of lithium causes the lithium anode and the entire battery to expand and contract periodically during charging and discharging. A change in the lithium anode causes a change in the volume of the entire battery by about 15%. As the thickness of the cathode increases and the excess of lithium, this relative volume change decreases. In order to apply lithium metal battery technology to electric vehicles, the battery pack needs to be properly designed to accommodate this periodic change in battery volume.<\/p><p><img decoding=\"async\" class=\"aligncenter size-full wp-image-46053\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Expansion-of-bag-batteries-in-different-electrolytes.jpg\" alt=\"Expansion of bag batteries in different electrolytes\" width=\"1000\" height=\"450\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Expansion-of-bag-batteries-in-different-electrolytes.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Expansion-of-bag-batteries-in-different-electrolytes-300x135.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Expansion-of-bag-batteries-in-different-electrolytes-768x346.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/07\/Expansion-of-bag-batteries-in-different-electrolytes-600x270.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">Expansion of bag batteries in different electrolytes<\/span><\/p><p>Expansion of bag batteries in different electrolytes.

SEI, which forms naturally by electrolyte decomposition, can hardly meet all of these requirements. Therefore, surface coating with a protective layer or artificial SEI on the lithium anode is an effective method.<\/p><p><strong>Lithium structure engineering.<\/strong> To minimize volume variations in the negative electrode of lithium metals, some 3D collectors or stable main structures with pre-stored lithium have been introduced.
