Batteries are becoming used in home solar setups. You’ll need one if you wish to store energy for use during power outages and when the sun isn’t shining. Your battery is the lifeline of your house if you have an off-grid installation. 

However, many companies are turning to newer battery technologies for solar energy storage due to supply chain issues and escalating lithium prices. The sodium ion is one of these battery technologies. This battery employs sodium, a cheap and plentiful material, instead of lithium-ion. 

Sodium-Ion Batteries

As a charge carrier, sodium is used in sodium-ion batteries. Because of their comparable internal structures, lithium-ion batteries and sodium-ion batteries are frequently compared. You may recharge sodium-ion batteries like lithium-ion, lead acid, and absorbent glass mat (AGM) batteries. 

Due to scaling issues with lithium-ion batteries, such as growing material costs and the requirement to get significant quantities of lithium to support battery manufacturing and demand, development for sodium-ion batteries goes back to the 1980s and has recently begun to pick up. 

Prussian blue as a cathode material has been the subject of substantial studies to improve Na-ion battery cells. The Na-ion battery pack may assume several useable configurations, including rectangular pouches and conventional cylindrical batteries. The many factors make this battery type perfect for commercialization and enable its application in energy storage, electric cars, and portable gadgets. 

Efficiency of Sodium-Ion Batteries 

Because they have the lowest energy density in the group, sodium-ion batteries are more prominent than lithium-ion batteries. Energy density is higher with NMC batteries. 

Despite having the same capacity, a 10 kWh lithium-ion battery will fit more compactly within your home than a 10 kWh sodium-ion battery. If you have little room on your land, this may be a problem, but Na-ion batteries are still developing, so things could change in the future.
