Problem
Lithium-ion batteries suffer from performance degradation due to lithium plating and dendrite formation, limiting charge speed, cycle life, and safety. These issues hinder the widespread adoption of electric vehicles and energy storage systems.
Solution
Sonocharge Energy has developed a technology that enhances lithium-ion battery performance by using acoustic waves to induce homogeneity of lithium ions within the battery cell. A custom-fabricated piezoelectric device, smaller than a fingernail, generates these acoustic waves. Surface-mounted onto a flexible circuit, the device is inserted underneath the battery module during manufacturing. When activated, the acoustic waves mitigate lithium plating and dendrite formation, leading to faster charging, extended cycle life, and reduced fire risk. The technology is compatible with various lithium-ion battery chemistries and form factors, including cylindrical, pouch, and prismatic cells.
Target Audience
The primary target audience includes manufacturers of passenger and commercial electric vehicles, energy storage systems, and high-performance applications that rely on lithium-ion batteries.
