Global solid-state batteries champions: looking for the next era of ningde

At the end of 2018, established in 2010, 24 m announced semi-solid lithium battery research and development enterprise, won $21. 8 million D wheel financing, capital from advanced ceramics manufacturer kyocera group and global trading company itochu.

from the company once all the rage then the decline of the United States A123 lithium iron phosphate battery enterprise spin-off, founded by China Taiwan scientists Dr Yet-ming Chiang, the goal is to reasonably priced high energy density batteries for electric vehicle development, from 2019 to start a small industrial plants, want to deliver the first batch of products in 2020.

24 m is a microcosm of a new global power battery race. From a global perspective, China, Japan, South Korea, Germany, France, the United States, Britain, Australia and other countries of many car companies betting solid-state batteries and battery businesses, to become the next superstar company & ndash; — In the field of solid-state batteries & other; Ningde age & throughout; , which is China's highest gem valuation company.

however, secretary general of the China association of chemical and physical power yan-long liu to & other; Travel throughout the second half &; （ wx：investchuxing) Analysis, solid-state batteries now is still in the laboratory, on the research and development also faces more difficult obstacle to customer service, is expected to real production after five years at least.

in November 2017, the Chinese government issued the 'energy-saving and new energy automotive technology roadmap' plan is put forward, the energy density of pure electric vehicle power battery monomer in 2020 reached 300 wh/kg, 2025, 400 wh/kg, 500 wh/kg in 2030.

this for existing liquid lithium battery is a high target. “ Tesla with battery is currently the world's highest energy density of power battery, tesla announced in early 2018 with panasonic joint research and development of the energy density of 300 wh/kg, 21700 monomer and domestic energy density batteries manufacturer monomer in commonly 230 wh/kg, to achieve the requirements of the national 2020 300 wh/kg challenge is very large. ” Qing tao energy chairman Feng Yuchuan explanation, but solid-state batteries are relatively easy to achieve this goal.

in a nutshell, solid lithium battery is relatively liquid lithium battery, is refers to the structure does not contain liquid, all materials in solid form of energy storage devices. Specifically, it consists of & other; The anode material + anode materials and electrolyte & throughout; Composition, while liquid lithium batteries by the cathode materials, anode materials and electrolyte and the diaphragm.

researcher at the institute of Chinese Academy of Sciences, solid ion group leader huang for & other; Travel throughout the second half &; （ wx：investchuxing) Introduction, solid state lithium batteries using lithium metal as the cathode, solid inorganic or polymer materials as the electrolyte, the energy density than using lithium-ion battery cathode material of the same type high - 20% 30%.

Feng Yuchuan analysis, & other The energy density of all solid state lithium battery monomer in the laboratory to more than 430 wh/kg, in the pilot phase of up to 375 wh/kg, in mass production stage can easily reach more than 300 wh/kg. ”

in the energy density, safety is the greater advantages of solid-state batteries. , Qingdao institute of bioenergy and process of the Chinese Academy of Sciences said associate professor dong unlined upper garment of wood, the liquid lithium battery choose to use organic electrolyte flammable and explosive liquid, solid electrolyte instead of liquid electrolyte, is recognized as we can boost one of the most effective ways of lithium battery safety performance.

materials department of tsinghua university associate professor liang-liang analysis, solid electrolyte non-flammable, also won't produce liquid electrolyte, so there is no corrosive, is the effective method to solve the problem of the battery safety, also accord with the trend of the development of the battery in the future.

at the same time, the solid electrolyte high mechanical strength and can effectively inhibit cell cycle in the process of lithium dendrite piercing, make possible the application of lithium metal anode.

according to the Beijing university of science and a master's degree in material science Yang Hao research, such as in solid-state lithium battery, as a result of the design of this kind of lithium metal anode, on the one hand, the weight of the battery energy density and volume energy density will be further promoted, and the positive electrode materials can be extended to more other materials; On the other hand, the application of lithium metal anode also brought lithium dendrite growth caused by security issues. And solid electrolyte has good mechanical performance, can effectively prevent the lithium dendrite penetration and inhibit its growth, with the function of the electrolyte and the diaphragm.

according to the state of the solid electrolyte in solid state batteries, solid-state batteries can be divided into solid and semi-solid cell, the electrolyte is solid, but in the batteries with a small amount of liquid electrolyte, which is the half solid electrolyte, liquid electrolyte, such as mentioned in this paper, the opening of 24 m products of the company. Mr.

in addition, jian-wei Lin and Zhang Yuzheng women will also be by way of contract transfer, combined to HuaJun industrial ( China) Co. , LTD. , transfer the second person of the company's shares held by 17600000 shares, accounting for the company's existing total of 7. 30%.
