What is the difference between all solid-state batteries and liquid lithium batteries?
Liquid lithium batteries are composed of four main materials: positive electrode material, negative electrode material, electrolyte, and separator;
All solid-state batteries replace the electrolyte and separator with a solid-state electrolyte.
What are the advantages of solid-state batteries compared to liquid lithium batteries?
Higher safety, higher energy density, longer cycle life, smaller volume
Classification of solid-state batteries
According to the current technological route, there are mainly three types:
Oxide solid-state battery, sulfide solid-state battery, polymer solid-state battery
According to the electrolyte morphology, it can be divided into:
Semi solid, quasi solid, all solid
The Three Key Technical Issues Existing in Solid State Batteries at Present
Unstable solid-solid interface contact affects performance performance performance
Poor conductivity of solid electrolytes
The use of lithium metal is prone to dendritic growth and poses safety risks
In Sichuan and Chongqing in July, the heat rises. In Pidu District, Chengdu, the semi solid battery production line with a design capacity of 1GWh invested by Qingtao Energy is still in the final preparation before production, and the first batch of semi solid batteries will be offline here; In the Liangjiang New Area of Chongqing, 90% of the first phase of the Ganfeng New Lithium Battery Technology Industrial Park project has been completed, and the PACK production line will also be put into operation this month. This will be the largest solid-state battery production base in China.
Jumping out of Sichuan and Chongqing, looking at the whole country and the world, the development of solid-state batteries is thriving: On July 4th, Toyota announced that it has made significant breakthroughs in solid-state battery technology, able to halve the weight, volume, and cost of batteries; On June 30th, Weilan New Energy will officially deliver its 360Wh/kg semi solid state battery, which has been developed for over two years, to NIO; Earlier, Qingtao (Kunshan) Energy Development Co., Ltd. obtained a huge increase of 2.7 billion yuan from SAIC Group
The layout of enterprises and the entry of capital have rapidly heated up the solid-state battery market. However, in the eyes of many industry insiders, solid-state batteries may seem like the "wind" is coming, but in reality, they are "obstructed and long".
