Some battery industry experts have said that in addition to power batteries for new energy vehicles, lithium batteries are also in great demand in areas such as energy storage and even electric bicycles. The energy storage industry is also calling on battery companies to create special batteries for energy storage applications, and the product development and production line layout of battery companies in the field of energy storage are attracting industry attention. CATL, EVE Lithium Energy, China Power God and other companies have clearly stated that they have special batteries for energy storage and are promoting mass production plans.
In terms of the choice of battery technology route, it was previously reported that South Korean LG, SKI, etc. have slowed down the pace of developing high-nickel ternary lithium batteries, and through the Polaris energy storage network to sort out the products launched by battery companies since 2019, and the products that will be mass-produced in the future, many domestic battery companies are still exploring the limits of lithium iron phosphate batteries.
On August 22, BYD revealed at the performance exchange meeting that the new generation of lithium iron phosphate batteries that will be launched in May-June 2020 will increase the volume specific energy density by 50%, the life of up to 8 years and 1.2 million kilometers, and the cost can be saved by 30%. BYD has been open to the supply of batteries since 2018, and in 2018, BYD said that the energy density of lithium iron phosphate monomer is 165Wh/kg and the package is 140Wh/kg. In the next two years, it is planned that the energy density of the monomer will be increased to more than 180Wh/kg, and the package will be increased to 160Wh/kg. In the future, BYD will also split the entire battery business to achieve an independent listing.
Earlier, foreign media reported that CATL announced that it had manufactured a sample of the NCM811 battery with an energy density of 304Wh/kg. The battery sample belongs to the second generation of products, the first generation of NCM 811 battery developed earlier is an ordinary anode made of graphite, but the second generation will use graphite mixed with a small amount of silicon to make a negative electrode to increase energy density, and it may take another year before mass production. In May 2019, according to Wang Wei, director of CATL energy storage business, since 2018, CATL has increased its global energy storage business layout, and will launch high-safety and long-life lithium iron phosphate battery products for energy storage in 2019.
EVE Lithium Energy
EVE’s performance report for the first half of 2019 stated that it has successfully developed and mass-produced special batteries for energy storage during the reporting period, which has greatly improved the cycle performance and safety and reliability of the cells. While the power battery ranks in the domestic installed capacity continues to rise, the layout of the energy storage battery business has been completed, and the market share has risen rapidly.
God of electricity
On April 29, 2019, Lishen Qingdao base phase I put into production and new product launch conference said that Qingdao Lishen Phase I production line will mainly produce LP71173207 (305Ah), LP54173207 (230Ah) and LP54173207 (170Ah) two specifications of three batteries, according to industry analysts, the latter is mainly used in the energy storage market.
On December 28, 2018, Guoxuan Hi-Tech released the record of interaction with investors, which revealed that the high-nickel NCM 811 ternary soft package sample prepared by it has passed the mid-term inspection of the Ministry of Science and Technology, with an energy density of 302 Wh/kg, and the negative electrode is made of silicon-carbon material. The mass-produced cylindrical lithium iron phosphate battery products have an energy density of 180Wh/kg, which can be used for models with a cruising range of more than 400km, reaching the international leading level. The newly developed 190Wh/kg cylindrical lithium iron phosphate cell product will also be mass-produced in 2019.
During the Shanghai Auto Show on April 17, Envision AESC, a power battery technology company under Envision Group, released a new generation of Gen5-811 power battery products, which will have a high specific energy of more than 300Wh/kg. The facelifted power battery will be officially mass-produced in Wuxi plant in 2020, and the total annual production capacity of the Wuxi plant will reach 20GWh in the future. According to reports, Envision AESC intends to build intelligent batteries defined by AIoT, and is committed to breaking through the boundaries of power battery performance and application with intelligent IoT, creating more intelligent scenarios, allowing electric vehicles to participate in fragmented renewable energy systems, and promoting the common development of clean energy and new energy automobile industries.
Recently, the “Nikkei Asian Review” reported that Tesla battery supplier Panasonic is preparing to establish a joint venture with Toyota to put into production of electric vehicle power batteries. In the future, Panasonic will transfer ownership of five battery production facilities in China and Japan to the joint venture. Toyota’s Panasonic battery joint venture produces batteries that are 50 times larger than those used in Toyota’s existing standardized hybrid vehicles. It is expected that the large-scale expansion of battery capacity will significantly reduce the unit cost of batteries. In the future, Toyota and Panasonic will also collaborate on the next generation of solid-state batteries, which are expected to increase the range of electric vehicles at a lower cost than today’s lithium batteries.
According to foreign media reports, South Korean energy company SK Innovation recently reached a cooperation with PolyPlus, a lithium battery research and development company, to jointly develop lithium metal batteries. The initial goal of this collaboration is to produce and test prototype batteries to demonstrate whether the increase in volume and weight has led to increased energy density and cycle life compared to existing lithium-ion batteries, in order to achieve technical advantages in lithium batteries.
According to news, Tesla has recently reached an agreement with LG, which will supply 21700 batteries for Model 3 and Model Y produced by Tesla’s Shanghai factory. In June, LG Chem and Geely Automobile Group will form a joint venture to produce batteries for electric vehicles, which plans to secure 10GWh of battery production capacity per year by the end of 2021. On July 9, LG announced its development plan for the next five years and will continue to make efforts in automotive power batteries, according to news, LG Chem plans to invest about 7.26 billion yuan to expand the battery production line in Nanjing, China, by 2020. According to Nanjing Daily in July, the LG lithium battery project with a total investment of 2 billion US dollars in Jiangning Binjiang Development Zone is mainly engaged in the research and development and manufacturing of power batteries, energy storage batteries and small batteries, and is currently under intensive construction.
Semi-solid-state battery developer 24M announced this year that it has delivered high-energy-density semi-solid-state batteries for commercial purposes for the first time to an unnamed partner. This new battery, developed by Dr. Jiang Yeming during his teaching in the materials department of the Massachusetts Institute of Technology, is said to transmit 10 times the power per unit volume of this semi-solid lithium battery, and the cost is only one-third of the current lithium battery. It is understood that the energy density of the semi-solid battery delivered this time exceeds 280Wh/kg, which is more than 10% higher than the most advanced 250Wh/kg energy density battery. However, 24M believes that the energy density of semi-solid batteries can reach 350Wh/kg, and even have the potential to exceed 400Wh/kg.
A Swiss battery start-up called Innolith has claimed that they have created the world’s first new 1000Wh/kg high-density lithium-ion rechargeable battery. Its energy density of 1000 Wh/kg is about four times that of current state-of-the-art lithium batteries”. Innolith’s approach is still based on traditional liquid electrolytes, but uses organic, highly flammable electrolyte solvents (salt-like materials) instead of more stable, non-flammable inorganic substances. Innolith said that this product will now be in Germany for preliminary trial production, and then the new battery will be brought to the market, and the subsequent commercialization may take 3~5 years.
