Advantages of bi-polar battery

Higher energy density

One of the main advantages of bi-polar battery is their higher energy density, which means they can store more energy in a smaller space. This is achieved by eliminating the need for a separate current collector, which reduces the weight and volume of the battery.

Faster charging and discharging

Another advantage of bi-polar battery is that they are able to charge and discharge faster than traditional battery designs. This is because the shared electrode provides a more direct path for ions to flow, which reduces the resistance in the battery and enables faster charging and discharging.

Lower battery production costs

Bi-polar battery also have the potential to reduce battery production costs. Bipolar batteries do not require separate current collectors, so the number of components required for the battery is reduced, which reduces the overall production cost.

Enhanced safety features

Safety is a critical aspect of battery technology, and bi-polar battery come with enhanced safety features compared to traditional batteries. The stacked electrode design inherently improves safety by reducing the risk of short circuits and thermal runaway.

Application of Bi-polar Battery

Electric vehicles
One of the most prominent applications of bi-polar battery is in the electric vehicle (EV) industry. The higher energy density and improved power output of bi-polar battery make them an excellent choice for powering electric vehicles. With their ability to store more energy in a compact space, EV equipped with bi-polar battery can achieve longer driving ranges.

Portable electronics
The demand for longer battery life and improved performance in portable electronics has driven the adoption of bi-polar battery in this sector. Smartphones, tablets, laptops, and wearables all benefit from the higher energy density of bi-polar battery, allowing for longer usage times between charges.

Energy storage systems
Bipolar batteries are also making significant contributions to the field of energy storage systems. These systems are essential for enabling efficient energy management in renewable energy sources, such as solar and wind power. Bi-polar battery facilitate the storage of excess energy generated during periods of high production, allowing for its later use during times of low production or high demand.

Maintenance of Bi-Polar Battery

Avoid extreme temperatures

Store the battery in a cool, dry place away from direct sunlight and heat sources.

Charge Regularly

Don't let the battery completely drain before recharging.

Partial charge is better

Consider charging to 80% capacity instead of 100% whenever possible.

Use the correct charger

Always use the manufacturer-recommended charger to ensure proper charging voltage and current.

How bi-polar battery work

The principle of operation of a bipolar battery is quite simple—in theory. One cell’s negative electrode and another cell’s positive electrode are located very close to each other (back-to-back). The cathode and anode are both coated on the substrate. The substrate with electrodes acts as a seal for the adjacently placed cells. Electrical current flows between cells directly through both electrodes and the thin, intermediate conductive substrate. Intermediate jumpers between neighbor cells are unnecessary in this case. The cells are placed in a common container. One or more containers are united into battery modules. See below for a schematic of a bipolar electrode module.

Q: What’s your after-sale service?

A: Our quality warranty period is made according to items and applications.

Q: What are bipolar batteries?

A: A bipolar battery is one in which the current collector for each cell is shared by the anode and the cathode. A Toyota illustration shows the anode and cathode materials coated on opposite sides of the collector in each cell.

Q: What is the difference between unipolar and bipolar battery?

A: In unipolar: the current always flows in the same direction. Each coil is dedicated to one current direction, meaning either the coil A+ or the coil A- is powered. The coils A+ and A- are never powered together. In bipolar: the current can flow in both directions in all coils.
