Is solid-state battery technology the key to extending electric vehicle range? Solid-state battery technology is undoubtedly the key breakthrough to extend the range of electric vehicles, hitting the bottleneck of energy density of traditional liquid lithium batteries, and at the same time solving the safety, charging efficiency and other constraints on the development of electric vehicles deep pain points.
The energy density of traditional liquid lithium batteries is close to the theoretical limit, and solid-state batteries using solid electrolyte instead of liquid electrolyte, compatible with lithium metal anode and other high-capacity materials, so that the energy density to achieve a qualitative leap. Part of the solid-state battery energy density developed by enterprises has been significantly higher than the existing mainstream products, which means that the same volume of the battery pack can store more electricity, directly promoting a substantial increase in range.
Liquid electrolyte thermal runaway, leakage and other risks, while the solid-state electrolyte is non-combustible, no leakage, fundamentally eliminating the battery spontaneous combustion potential. Even in the face of extreme tests such as pinpricks and high temperatures, solid-state batteries can still maintain stable operation, thus indirectly improving range performance.
Although solid-state batteries still need to be optimised in terms of charging speed and cycle life, their disruptive improvement in range has made them the focus of the industry. Currently, global car companies and battery manufacturers are accelerating the research and development of solid-state batteries and mass production layout, some companies have entered the road test or small batch production stage.
Is solid-state battery technology the key to extending the range of electric vehicles? Solid-state batteries are expected to gradually replace liquid batteries and become the mainstream configuration of electric vehicles in the next few years. Range anxiety will no longer be the core obstacle restricting the popularity of electric vehicles, and solid-state battery technology will become a key force driving the energy revolution in the transport sector.
