One of the major concerns of conventional Lithium ion batteries is the high temperatures generated during charging. Thousand Oaks, California-based Battery Streak is designing a battery that charges at no higher than 91 ° F (33 °C) while charging at 6 C-rate, less than current rechargeable batteries on the market that can get as hot as 130 °F (55 °C) when charging at 2 C-rate or less..

Battery Streak batteries charge with a different energy storage mechanism than traditional batteries. In a conventional Lithium ion battery, the energy is stored and released through a highly resistive chemical reaction. "This chemical reaction is not efficient and thus heat is produced as a byproduct," says Matt Lai, Battery Streak's technology development manager. "Our batteries do not store energy with such chemical reactions. Instead the energy is stored on a surface without chemical phase change, like a capacitor." 

The proprietary Battery Streak technology produces electrodes that work much like a sponge, with pores thousands of times smaller than a human hair, providing a very large surface area for energy storage. Similarly, when energy is released, there is no chemical phase change and virtually no heat is produced. 

"This technology results in very fast charging and batteries that remain cool to the touch," says Lai. "While everyone wants a faster charging battery, from a safety standpoint the heat generated while charging is just as important. Battery Streak testing consistently shows that the company's batteries charge between 80.6 °F (27 °C) and 91 °F (33 °C), well below temperatures that could generate enough heat to cause batteries to catch fire."

In addition to its cooler charging technology, Battery Streak has achieved a fast charge rate from empty to 80 percent charge in 10 minutes, regardless of battery or pack size.

Battery Streak hopes to begin battery production for commercial use in the second quarter of 2020.
