Black technology gives the lithium battery a chance to resurrect

As the electric vehicle (EV) market continues to grow, the secondary use of these batteries is creating new opportunities for the energy storage market after the vehicle batteries no longer have sufficient capacity.

“The battery power in an electric car usually decays to about 80% in about 8 years, so it needs to be replaced regularly.”

Although these batteries may no longer be suitable for use on a vehicle, this does not mean that the battery has been exhausted. They can be used in the field of stationary energy storage, such as commercial and residential, to create a "second life", which is also called "the use of lithium batteries."

If you can look at it in a rational way, this may be a very attractive market, especially considering that lithium-ion batteries are not nearly 100% recycled like lead-acid batteries. Today, several original equipment manufacturers (OEMs), including Tesla and Mercedes, have made appropriate modifications to their modules for stationary energy storage.

“However, there are still many challenges in reusing lithium batteries.”

For example, configure enough batteries in the same type of module or component and maintain voltage consistency. Another challenge is to determine the battery in the module or component, different performance levels, and energy efficiency conditions. An appropriate diagnosis and testing must be performed before switching to a new application.

Obviously, systems based on the same standardized module and output power produced by a single OEM may have significant advantages in the lithium battery ladder market.

Cost parity has always been a major factor driving energy storage systems, and lithium-ion batteries have become the dominant technology due to their higher energy density. However, this is not a problem for the reuse of decommissioned lithium batteries.

“The module that gets the “second life” has no fixed cost and only needs to pay variable costs such as operation and maintenance.”

Depending on the application of the module and the original design, thermally conductive materials such as caulks and adhesives can be used to make it easier to remove the battery module. The design of LORD caulks and adhesives have fully taken into account the use of batteries.

Renewable energy is gradually becoming mainstream and plays an important role in the development of sustainable energy systems. The development of new business models in the energy sector has created innovative new energy storage solutions while providing opportunities for re-using lithium batteries for decommissioned electric vehicles.
