How do you increase battery capacity?

Adding more battery modules: increasing energy capacity by adding more cells by installing additional battery packs. Upgrading battery packs: replacing whole battery packs with better performing or cheaper technology, either lithium-ion or new chemistries such as sodium-ion.

Can lithium ion batteries be connected in parallel?

When assembling lithium-ion cells into functional battery packs, it is common to connect multiple cells in parallel. When lithium ion battery packs are connected in parallel and cycled, matching of internal resistance is important in ensuring long cycle life of the battery pack.

Can a battery case expand?

Only if it is not possible to have the case expand, a failure point must be provided to ensure the case will vent. Most of this is basically preventing a fire from becoming an explosion. If a battery type is used that must vent, IE 18650, then the casing must be able to vent or expand as well.

Do puffed up batteries expand or vent?

As far as puffed up batteries, the battery must be designed to either expand or vent. Bag type batteries like the one in your photo expand, hard shells like 18650s vent.

What is augmentation in energy storage?

Augmentation is the action of making something greater in size. For battery energy storage systems, this means increasing the battery's energy capacity. This could be repowering a system following degradation or a commercial decision to increase the project’s duration.

Why do batteries need augmentation?

Augmentation also helps to manage degradation (also known as repowering). Battery energy storage systems can lose up to 5% of their available energy capacity through degradation within the first year of operation and 40% after 15 years. Degradation is mainly linked to cycling.
