Large square Prismatic Lithium Ion Battery & rechargeable lifepo4 cells

A prismatic lithium ion battery normally produced by a Steel or aluminum casing, and Some of Big Lithium ion battery with an ABS casing. This type of Square lithium ion battery is normally an old production. The battery casing purpose to increases the stability of battery cells. In turn, this unique design tends to make prismatic cells thin and light, and also with the feature of space saving. A rectangular shape of thin prismatic cells offers better layering than cylindrical cells. It gives more flexibility for battery design engineers. The popularity of prismatic cells is also related to their large capacity. For example, a compact 12V battery pack could be easily created by connecting four prismatic cells together. Therefore, prismatic cells are commonly used in large power applications such as Battery energy storage systems and also electronic cars.

Benefit to use a Large Square prismatic cells

Prismatic lithium ion batteries are made up of many positive and negative electrodes sandwiched together. It has much less internal resistance. That’s very nice for big current discharge. When use a Prismatic li ion cell for a battery packs. Its also easy to expend the pack capacity without too much cell in parallel. A High quality large square lithium cells can save much more space then any other kind of rechargeable lithium batteries. So When you decied to make a large capacity battery pack. High quality prismatic lithium ion cell is a very good choice.

A prismatic lithium batteries capacity normally starts from a 20Ah battery cell and go up to a 200Ah. They are normally design for electric vehicles (EV) and solar energy storage  systems( ESS).and have a long battery life of up to 5000 charge cycles.

Easy Expend the Battery Pack capacity.

Higher structure’s energy-dense

Less Internal resistance From packs

Price cost Lower

Cylindrical Cells VS Prismatic Cells

The Major advantage of cylindrical batteries in most situations is that they are has a standard dimensions. Production cost lower because of high quantity production in manufactured. In this way, people can easy get and pays don’t need to wait too long for the production time. Such as most popular size model: 18650, 26650, 32650, and 32700. They are flexible for any combination when you make a pack. Increase battery pack voltage and capacity could be much easy. Also battery pack shape can be flexible design.

S prismatic cell normally with higher capacity and takes much more space. If you want to make a small pack, it is not a good idea to use it. Another risk to use a Prismatic cell is:

  1. Normally a prismatic cell is design for EV or Big ESS. It is not easy find exactly required size in market. Mostly people buying a second hand or used cells.
  2. Make sure you order a high grade A prismatic cell is a key for good quality battery pack. Otherwise you would better use normal standard sylindrical cells.

Widely Application

Solar Energy storage system

For Battery Home Energy storage systems like most popular 5Kw/10Kw powerwall

electric Golfcart

A Big large capacity Lithium battery can keep the golfcart light weight and long distance running.comfortable

electronic vehicle

EV required very high quality batteries. As It is the highest standard for All kinds of Li ion or LiFePo4 cells.

tricycle/pedicab

Electric pedicab has much more space and possible to install larger battery cells. Of cause people dont’ want a lead acid in it nowadays.
