At Leclanché we develop energy storage technology and battery systems for many decades combining our century long expertise in the best solution for our customers.
The choice of the right energy storage technology is determined by the application.
锂离子电池是基于技术y where lithium ions are the charge ‘carrier’ and can move back and forth from the cathode (positive current collector) to the anode (negative current collector). Cathode and anode are electrically isolated from each other with a separator. An electrochemical cell consists of two currents. One external electric current, and one internal ionic current. The separator is designed to allow for an ionic current, but not an electric current.
Therefore a separator is used which has the double function to isolate and to allow the ions to pass through.
When charging the battery the ions move from the cathode (positive) to the anode (negative). When discharging the ions move back to the cathode.
This process can be repeated a number of times during the life of the battery cell which is called the cycle life of a battery
High quality manufacturing yields high performance cells
One of the most important factors for the performance of a battery cell is the way the cell is produced. The production of a cell consists of several steps bringing it from raw material all the way to an assembled, activated cell that is ready for operation.
Leclanché is unique in using a water based production process for the electrodes which eliminates the need to use polluting solvents and therefore we have a more sustainable production process.
Leclanché, in its factory in Germany, has a fully automated production line where both Lithium Titanate Oxide and Lithium Graphite/NMC cells are produced. The production starts with the processing of the powders through coating on the anode and the cathode. Next the cathodes and anodes are assembled in a roll to roll process together with the ceramic separator. All these layers are laminated to assure optimal integrity of the cell and ensure maximum performance over its life.
Once all these layers are stacked, a tab is welded onto the cathodes and anodes and next they are inserted into a pouch. After adding the electrolyte, the pouches are sealed and formed during which they are charged for the first time in their life.
After the formation the cells undergo a final quality check and they are ready to go into the application.
Battery cells don’t make a system yet. They have to be integrated into a battery module together with a Battery Management System, a Battery Controller and Switch Unit.
Leclanché provides battery modules with integrated Battery Management System (BMS) that monitors the temperature and operating voltage of each individual cell in the module and takes care of balancing the cells.
Leclanché designed the battery modules to accommodate both Lithium Graphite/NMC and Lithium Titanate Oxide cells. Individual battery modules are built into a string to reach the right level of energy storage and the required voltage levels for the application. Each string is controlled by a string controller.
Battery modules and systems area available for both stationary applications in 19” rack mount format and for mobile applications.
In stationary applications the racks are built into systems with airflow cooling. Mobile applications often need customized battery packs because of space limitations. The cooling strategy for these battery packs has to be aligned with the available space and surrounding.
For these applications Leclanché developed the flexible mobile system which can be fitted with cooling systems based on water or air flow systems.
The application
In all applications the battery system has to cooperate seamlessly with the energy source and the load. Be it in a bus or in a microgrid, a ferry or an electricity grid, the battery has to be charged and discharged at the right speed and the right moment.
This requires a seamless integration of the battery management system, the charge/discharge controller and the overlying energy management system.

Leclanché’s lithium-ion battery solutions offer unparalleled energy density and performance for electric and hybrid applications while offering at the same time advanced safety and reliability. Our solutions remain highly efficient without adding unnecessary weight and our modular design ensures the optimal use of all available space in the machine. Excellent lifetime and fast charging provide compelling cost of ownership.
LeclanchA©因此能够提供全面的energy storage solutions for industrial machines such as AGVs, forklifts, material handling equipment, and special working machines. Our systems offer a range of benefits and functionalities: energy regeneration in cyclic load profiles, emission-free and silent operation, optimization and downsizing of the prime mover and improved maneuverability.
The most optimal battery cell chemistry is determined by the discharge and charge power requirements, as well as ambient conditions. Leclanché provides two lithium-ion battery technologies within the same form factor: Lithium Titanate Oxide (LTO) a high power battery and Lithium Graphite/NMC (G/NMC) a high energy battery. A Leclanché battery system may be adapted to any machine equipped with an electric powertrain.
The marine market continues to rely on traditional propulsion power systems, which no longer fulfil the requirements for the clean and efficient use of energy. New emission and noise regulations prohibit the use of conventional solutions in ports, natural reserves, special marinas, and other low-emissions or low-noise areas. Leclanché battery solutions in diesel-electric or full-electric systems offer substantial savings thanks to reduced diesel / oil consumption as well as decreased maintenance and service costs. High safety, availability and efficiency are further essential reasons to rely on Leclanché battery solutions in all marine applications.
Our storage system has multiple functions:
Innovative companies look at automating material handling to improve efficiency and decrease operational costs. But the batteries used in these automatically guided vehicles have been far from innovative. Lead acid technology hasn’t evolved much in the last century, but with the introduction of lithium-ion amazing new concepts of energy storage are available.
Leclanché lithium titanate oxide (LTO) technology is perfectly suited for AGVs resulting in ultra-fast charge batteries.

AGV和机器人应用程序有助于减少复发ring tasks typically performed by humans. Our customers have the challenge to design systems with a minimum of space, the lowest possible costs and the highest reliability. With our ultra-fast charging technology the efficiency of each vehicle increases and optimizes the available surface for key operations. We offer a solution that achieves the fastest payback time for the initial investment and operational expenses.
Our specialists can help you optimize the required system requirements for battery, charger, docking station and service level agreement including remote management.
Remote power generation
In many areas it is not simply to plug into the wall outlet and have electricity. Very often on islands and in remote villages or industries, connecting to the main grid can be very expensive or even impossible.
Electricity often comes from diesel generators. This, however, requires a stable and expensive supply of diesel fuel, and involves high maintenance costs. The result is electricity production that is 4 to 10 times more expensive than in other well-supplied areas – as well as being noisy and polluting.
可再生能源
In this context, solar and wind energy are rapidly gaining ground in these applications as their costs have declined steeply.
These sources of energy are dependent on nature: clouds cause the output of a solar plant to decline rapidly, for example an increase in wind speeds results in a sudden surge in the output of the wind turbine. In this regard, Leclanché’s Lithium Ion-based battery storage systems act as a stabilizer in a microgrid system, with their ability to constantly absorb or inject power from and to the system
Energy storage to reduce diesel consumption
Diesel generators run up to 3 times more efficient when they are running at full capacity yet in many applications they are only used at a fraction of their capacity. Additionally, running at a low load causes damage to the generator. This shortens the maintenance intervals and increases operational expenses.
By combining a diesel generator with a storage system, the use of the generator can be optimized and it can even be switched off. This leads to significant savings by:
Providing Grid Services with a battery system
Historically the electricity supply system is characterized by stable generation and variable loads. However in most countries renewable electricity production is rapidly becoming the cheapest source of electricity. Renewable energy sources have a continuously changing production profile with clouds moving over solar plants or variations in wind at wind turbines.
There is an increasing need for flexibility options to maintain stable grid operations!
