A new patent filed by Tesla Inc. (NASDAQ:TSLA) could provide a key breakthrough in improving battery performance and efficiency, especially in high temperatures.

Improved Efficiency Of Battery Storage Devices

In a patent filing with the USPTO published on Thursday, the company details a new ‘dicarbonate' solvent (Dimethyl 2,5-dioxahexanedioate or DMOHC) and a new Lithium bis(fluorosulfonyl)imide (LiFSI) salt, that can help a Lithium Ion battery perform better under high voltage and high temperature conditions.

The patent details its findings, which suggest that the new solvents help Li-ion batteries maintain stability for up to 85 degrees Celsius (185°F), and help them retain almost 99% capacity even after 3,500 hours of use.

The patent also details improved safety by minimizing gas buildup, which can become a fire hazard if the battery containers swell up and rupture, something which can ...
