Li-Protect - Chemical overcharge protection for lithium-ion batteries

Summary

The invention chemical overcharge protection describes carbene complexes which are found within a lithium-ion battery above a determined charge potential, e.g. when overcharging the battery, decompose. The accumulator is thus protected due to the chemical additive in the electrolyte from overheating and explosion and increases the life.

Technology Benefits

Effective protection of the
battery in case of battery
management system failure
 No adverse side effects during
battery operation
 Increased security for the Libattery
operation in vehicles
 Simple Synthesis

Technology Application

Lithium-ion batteries are widely used as mobile energy storage. Due to improper operation, the accumulator can be irreparably damaged.
Li-Protect prevents overcharging and the consequences of over-voltage and makes the lithium battery safer.
