New ‘condensed battery’ with 500 Wh/kg energy density
26/4/2023
News
China’s CATL has launched a new semi-solid state battery type, known as a ‘condensed battery’, which is said to offer a 500 Wh/kg energy density while being safer than regular lithium ion batteries.
CATL is one of the biggest lithium-ion battery producers and one of the primary cell suppliers to Tesla. It is understood that the new condensed battery has an energy density of almost double that of Tesla’s current battery cells.
The condensed battery leverages highly conductive biomimetic condensed state electrolytes to construct a micron-level self-adaptive net structure. This structure can adjust the interactive forces among the chains, improving the conductive performance of the cells and, in turn, increasing the efficiency of lithium ion transporting while boosting stability of the microstructure, reports CATL.
The battery integrates a range of technologies, including ultra-high energy density cathode materials, innovative anode materials, separators, and manufacturing processes, offering excellent charge and discharge performance as well as good safety performance, the company adds.
It believes the new technology ‘will open up a new scenario of electrification centring on a high level of safety’.
CATL is currently cooperating with partners to develop electric passenger aircrafts utilising its new battery technology. Meanwhile, an automotive-grade version of the condensed battery is expected to be put into mass production this year.
