Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

Internal resistance

Stacking cells have lower internal resistance,winding cells have related higher IR.

Winding cell is usually a single pole ear, while a stacking cell can be seen as a multi pole ear, greatly reducing its internal resistance.

The different internal resistances result in different heat generation and capacity decay rates during the charging and discharging cycles

of finished batteries. It is evident that stacked batteries have slower capacity decay.

 

Cycle life

For stacking batteries, the internal temperature distribution is relatively uniform,Due to the unidirectional heat transfer between the electrode and the

separator, the temperature gradient distribution of the winding battery is relatively severe, resulting in high internal temperature and low external temperature.

Uneven temperature distribution leads to the deactivation of active substances at high temperature positions during the charging and discharging process of the

battery, which prevents the function of lithium ion deintercalation and affects the rapid decay at other positions, thereby affecting the performance of the battery.

 

The internal stress of the battery cell

The edge of a winding battery cell is where stress is concentrated. Based on past battery disassembly analysis experience, the bending of the electrode is more prone to

micro short circuits, electrical breakdown, and lithium deposition.The stress concentration point is the primary location for battery deactivation, which also leads to a decrease

in the cycle life of wound batteries.

 

Charging&Discharging rate

The stacking cell is equivalent to parallel connection of multiple electrodes, making it easier to complete high current discharge in a short period of time, which is beneficial for the rate

performance of the battery. The winding process, on the other hand, is exactly the opposite, with a single pole ear resulting in slightly poorer rate performance.

 

Battery capacity density

Stacking batteries have a higher capacity density because their internal space is more fully utilized.

The winding type battery has circular cells on both sides and the last two layers of membranes occupy a certain thickness, resulting in a lower capacity density.
