disadvantages

Lower energy density: Sodium-ion batteries typically have a lower energy density than lithium-ion batteries, which means they may not be as efficient at storing and releasing energy.
Limited availability of materials: While sodium is more abundant than lithium, the availability of certain materials needed for sodium-ion batteries, such as high-quality anode materials, is still limited.
Compatibility issues: Since sodium ion cell has different electrical characteristics than lithium-ion batteries, they may not be compatible with certain electronic devices and systems designed to work with lithium-ion batteries. So the application scenarios are not very extensive.

Does 18650 sodium ion cells need BMS

18650 sodium ion cells require a Battery Management System (BMS) for safe and efficient operation. A BMS is an electronic system that is responsible for monitoring and controlling the charging and discharging of the battery cells. It helps to ensure that the battery operates within safe limits and prevents overcharging over-discharging and over-temperature conditions that can lead to cell damage or failure.

The BMS also balances the charge levels of each cell in a battery pack to ensure that the cells are charged and discharged equally. This helps to prevent any individual cells from being overcharged or over-discharged, which can lead to reduced performance or even catastrophic failure of the entire battery pack.

18650 sodium ion cell vs 18650 lithium cell – which is better

In terms of energy density, lithium-ion cell has a higher energy density than sodium ion cell, which means they can store more energy per unit volume or weight. This makes lithium-ion batteries more convenient for applications where expanse and consequence are a bonus.

On the other hand, sodium ion cell is a more plentiful and less pricey material as compared to lithium, which could make Sodium ion cell less costly to produce than lithium-ion batteries. However, the overall cost of a battery system depends on many factors, including the availability of materials, manufacturing processes, and the scale of production.

Heeding safety, sodium-ion batteries are generally considered to be more secure than lithium-ion batteries as they are less prone to thermal runaway, a phenomenon that can lead to fire or explosion. Both varieties of batteries can be made secure with the relevant technique and safety characteristics.

Regarding cycle life, both types of batteries can have a long cycle life, but at present, lithium-ion batteries have a higher cycle life. Lithium-ion batteries have a well-established supply chain, which means there is a large ecosystem of suppliers and manufacturers that can provide support for these batteries. However, sodium ion cell has not yet been fully popularized, and there are relatively few companies selling sodium ion, so it is not so easy to buy.
