New energy power battery energy storage glue coating

Could a conductive polymer coating make EV batteries more affordable?

The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture. Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a conductive polymer coating -- called HOS-PFM -- that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles.

Could new polymer coating boost electric vehicle batteries?

Nature Energy, 2023; 8 (2): 129 DOI: 10.1038/s41560-022-01176-6 DOE/Lawrence Berkeley National Laboratory. "Electric vehicle batteries could get big boost with new polymer coating." ScienceDaily.

How are structural adhesives used in EV batteries?

Structural Adhesives used in EV batteries must withstand high mechanical loads, as well as exposure to temperature extremes, humidity, and other harsh environmental conditions. The following methodologies are used to test the performance: the weight of the battery or vehicle, or internal stresses generated by thermal expansion or contraction.

Can debondable adhesives be used in EV batteries?

Functional materials such as debondable structural adhesives and debondable thermally conductive adhesives will enable OEMs and battery manufacturers to include debond-on-demand solutions into EV batteries, thereby extending the maximum lifetime of batteries and easing the dismantling process for EOL applications.

Could a HOS-PFM coating increase lithium-ion batteries' energy density?

The researchers recently described these findings in the journal Nature Energy. The HOS-PFM coating could allow the use of electrodes containing as much as 80% silicon. Such high silicon content could increase the energy density of lithium-ion batteries by at least 30%, Liu said.

What's new in EV batteries?

"The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture," said Gao Liu, a senior scientist in Berkeley Lab's Energy Technologies Area. The HOS-PFM coating conducts both electrons and ions at the same time.
