Lithium Ion technology
-
Introduction
A lithium ion battery cell is based on a technology 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 cellsOne 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.
Modules & Systems
-
The battery system
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 applicationIn 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.

Solar street lighting – light without the powerline
-
Providing light at night even in remote locations is important for safety and security. However in many locations there is no ready infrastructure to connect streetlights.
Powering streetlights also requires a lot of energy which most of time is generated by conventional (coal- or gas fired) power installations, creating CO2 and other greenhouse gasses.
Local power, local light
Generating the energy for the streetlight locally with solar PV panels has a lot of benefits but to convert the solar power into night-time light it needs to be stored.
Leclanché provides a complete solar streetlight storage solution which consists of Leclanché Lithium Ion battery modules together with a battery management system and light control system.
The battery modules are based on Leclanché Lithium Titanate cells which provide a lifetime of more than 20 years to the streetlamp with a very high reliability.
Their large operational temperature range from -20°C to +55°C make them very suitable for operation in remote areas both in cool and in warm climates. Streetlights with Leclanché battery modules are operating in the desert in Abu-Dhabi where the temperature inside the mast easily reached over 50 degrees.
Markets & Solutions
Transportation

Battery solutions for transportation
Leclanché is leading the market with technologies for transportation applications. Our two lithium ion technologies offer very distinct capabilities enabling to design battery systems that are optimally geared for the application of the customer.
Lithium Titanate Oxide – high power
In most transportation applications a lot of power is needed for instant, short term traction and torque. To provide this in an electrical vehicle a battery has to be able to rapidly discharge and provide the energy for this torque.
Leclanché’s Lithium Titanate Oxide (LTO) batteries are best suited for this.
Lithium Graphite/NMC – lots of energy
For longer travel distances a lot of energy is needed. Once the vehicle is in motion, a battery that can gradually and efficiently discharge it’s energy to the drivetrain is the needed solution.
For this Leclanché provide its Lithium Graphite/NMC (G/NMC) batteries which have a high energy density.
Design with our customers
In each project a specific design for the battery system has to be made. Leclanché has an experienced team of engineers and specialists who work with our customers to design the battery pack optimised for their application and fitting in the available space in the vehicle. Through the whole design-in process we support our customers coming to the best solution. 
Buses
-
Energy storage solutions for transportation
A key component in the powertrain electrification is on-board electrical energy storage, which is usually a battery. The battery works as an energy buffer in hybrid vehicles, and as a single energy source in full-electric vehicles. The most suitable of the modern battery technologies is lithium-ion that can be optimized for required energy and power. Leclanché can provide a high power option (LTO) and a high energy option (G/NMC) with the same form factor and a revolutionary hybrid battery that combines both of them.
The most optimal battery cell chemistry is determined by the discharge and charge power requirements (operating strategy) as well as ambient conditions. In a full electric bus driving can usually be done with an energy-type cell, but a power-type cell (LTO) is often more feasible due to the operating strategy. A single bus can operate a full shift with a relatively small battery if the battery is charged at bus stops or at the bus terminal.

Marine
-
Energy storage solutions for marine applications
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:- acts as a small uninterrupted power supply (UPS) for emergency back-up for critical equipment such as navigation, lights, steering and firefighting;
- acts as a large UPS for silent vessel operation;
- offers an alternative contingency reserve (replace spinning reserve as hot standby)
- provides power boost energy storage for short term vessel pull power or top speed vessel operation;
- allows peak shaving for economy of operation;
- acts as green energy storage with a secondary fuel tank for wind, solar, hydro or shore power; and
- allows for battery-only operation for short to medium distances.
AGV and Robotics
-
Leclanché fast charging high power battery packs for AGVs

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.
Microgrid solutions / Utilities / Grid
Microgrids
-
Battery storage to create stable micro grids
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.
Renewable energy sources
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
Diesel Saving
-
Save diesel and money through energy storage
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:- Reducing fuel consumption
- Increasing maintenance intervals and extending the life of the generator
Renewable energies save fuel. Leclanché battery solutions combined with solar and/or wind generation offer independence from rising diesel costs. This is particularly true in remote areas not connected to the utility grid where battery storage is a core component of a microgrid system.
Any electricity system that runs on diesel generators will benefit from significant savings in consumption by implementing a battery storage system, which- handles peaks in demand without burning extra diesel;
- optimizes generator efficiency to reduce energy wastage; and
- automatically switches off the diesel generator during the day to rely on energy supply from the battery’s combined with a solar powered system.
Grid Ancillary Services
-
Battery storage for grid ancillary services
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!
Battery energy storage systems to provide primary control reserveAdvantages of a Battery Energy Storage System
- A Battery Energy Storage System (BESS) is able to inject energy into the grid or absorb it from the grid when needed.
- The operational costs of a BESS are low compared to a conventional power station burning gas, diesel or coal to provide primary control reserve. There is very little energy required to operate a BESS.
- Additional benefit is that a BESS is scalable and flexible. Its capacity can always be increased by adding additional storage racks or containers.
- A BESS can be installed in just 6 months, compared to a standard power station dependent on the approval delay and delivery time. It can also easily be moved to another location when required.
- A BESS does not harm the environment.
Home and small business storage
