Stackable Batteries
Stackable battery systems are modular energy storage units that allow for easy expansion and flexibility. They are an ideal solution for residential and commercial energy storage applications.
Stackable lithium batteries are assembled with the base and battery management system on the bottom, then two to eight battery modules are stacked on top like Lego bricks. This allows them to have larger capacity and power output than winding batteries.
Large Capacity
A stacked battery cell is a new type of lithium battery technology that can increase the electrode area and capacity. It uses a lamination process instead of the traditional winding battery production method. This allows it to have a more compact shape and better rate performance. It also helps distribute heat evenly throughout the battery, which can prolong its lifespan.
Stackable batteries are scalable, making them ideal for residential and commercial storage applications. They can also be used in hybrid energy systems to support renewables like solar and wind power. In addition, a stacked system can provide redundancy to ensure that the system continues to function even if one or more modules fail.
HOPPT BATTERY is a leading manufacturer of stacked batteries, and we use innovative design techniques to make our battery modules more robust. Our patented BMS technology can monitor individual modules and adjust the current and voltage to maintain balance. It also has multiple safety functions to prevent overcharge, over-discharge and high/low temperature. This enables us to offer a 5-year warranty for our stackable lithium iron phosphate batteries.
High Rate Performance
Stackable batteries can be used in a wide variety of applications, including power and energy storage. They can be stacked in series or parallel to maximize capacity and power output. They are also easy to install and have wall-mounted-battery an attractive appearance. In addition, they can withstand high-load conditions and have an extended cycle life.
Compared to winding batteries, stackable batteries have a higher energy density. This is because the corner of a winding battery has a curvature, which means that there are gaps in the inner and outer layers at the corners. During repeated use, these gaps will expand, leading to inconsistent internal stress in the corners of the winding battery. The resulting wavy deformation will cause the interface of the battery to deteriorate and lead to uneven current distribution.
Stacked thin-film batteries are able to operate at high C-rates, which is essential for high power applications. The technology offers several advantages, such as increased energy density and precision in manufacturing. In addition, stacked batteries can be produced with a variety of shapes and sizes to meet customer needs.
High Capacity Density
In order to increase both energy storage and power output, vacuum-processed thin-film cells are monolithically stacked together in a battery and electrically connected in series or parallel. When the cells are connected in series, the voltages of the stacked cells add up while the capacity is limited by the cell with the lowest voltage.
The stacked battery makes full use of its corner space and has higher volume specific capacity than the winding battery under the same volume of cell design. The stacked battery also has a discharge platform that is closer to its self-discharge platform, which makes it ideal for applications with high energy consumption.
Incorporating a stackable battery backup into your home solar system helps to reduce energy dependence and achieve energy independence. With the ability to flexibly expand capacity, the system can grow in line with increasing electricity demands or solar array expansions. The batteries can also be used to store excess solar generation and provide back-up in case of a power outage. In addition, the batteries can help facilitate variable renewable integration by providing services such as frequency response, voltage support and load following/ramping.
Low Internal Resistance
The internal resistance of a battery is a key factor that influences its rate performance and discharge platform. As electric current passes through the battery, it generates heat and wastes energy, which is a loss of capacity for the battery. The higher the internal resistance, the less efficient the battery is.
The stacked batteries produced by the lamination process have a much lower internal resistance than those made through winding. The reason is that the cell stacking batteries have more tabs than the winding type, and each tab has a shorter electron transmission distance, which greatly reduces the internal resistance of the battery.
The stacked battery has an even stress distribution 48V solar system and is able to avoid the problems such as powder dropping and burrs caused by bending deformation in the winding batteries. The resulting flat interface is also a guarantee of the battery’s safety. Moreover, the stacked battery has a higher energy density than the winding battery because it can make full use of the corner space, and the number of pole pieces is lower.
Wide Application
As for the application, a stacked lithium battery can be widely used in various fields such as drones, RC models, agricultural plant protection, sports cars and other vehicles, special and maritime batteries, energy storage systems, wearable devices, and AR/VR. The modular design of the stackable lithium battery enables easy scalability, allowing the capacity to be adjusted according to specific requirements.
The stacked battery cell adopts lamination technology, which means that elements and separators are folded into zig-zag layers instead of being rolled up like a winding battery. This makes the stacked battery much more compact and more efficient in terms of energy density. In addition, heat is distributed more evenly throughout the battery, prolonging its lifespan.
Home Grid Stacks store the solar energy generated during the day, then power appliances and electronics in your home when the grid goes down. You can even add expansion packs to make a more powerful backup system for your entire house.
