Lithium batteries. Energy efficient and sustainable. Why choose them?
We know that if you have come this far, it is because you are considering a key decision for the energy future of your company. Perhaps you have already installed a photovoltaic system and are now looking to take the next step. Or maybe you simply need to reduce your dependence on the grid, stabilise your energy costs or gain autonomy.
What are lithium batteries and why are they the future of energy?
Lithium batteries are electrical storage systems that use lithium ions as charge carriers between the anode and cathode. Their main strength is their high energy density, meaning they store more energy in less space and weight than traditional technologies (lead-acid or NiMH). This translates into more compact, lighter and more efficient equipment.
Unlike other solutions, lithium batteries support high depths of discharge (DoD) with typically high round-trip efficiency, maximising the energy that is actually usable. Furthermore, their low maintenance and lower self-discharge make them a reliable choice for critical applications and intensive use.
El futuro energético exige flexibilidad, digitalización y sostenibilidad. El litio encaja a la perfección: permite integrar fuentes renovables, estabilizar redes, electrificar el transporte y desplegar almacenamiento distribuido. Con la evolución de químicas como LFP (fosfato de hierro-litio) o NMC (níquel-manganeso-cobalto) y sistemas de gestión (BMS) más inteligentes, el litio ofrece un equilibrio cada vez mejor entre seguridad, coste por ciclo y rendimiento.
Applications of lithium batteries
- Self-consumption and residential/industrial photovoltaics
They store surplus solar energy for use during hours without sunlight, reducing dependence on the grid and optimising electricity bills (peaks, rates, demand). - Maritime systems and electric mobility
In boats and vehicles, lower weight and high performance improve range, manoeuvrability and the onboard experience, with less noise and emissions. - Commercial and industrial (C&I) storage
Supports peak shaving, backup power (UPS), and energy arbitrage; provides stability and operational resilience. - Microgrids and electrification of remote areas
Combined with renewables (solar/wind), they ensure a continuous supply, reducing the use of diesel generators and fuel/logistics costs. - Critical applications and infrastructure
Data centres, hospitals, telecommunications and ports use lithium for its fast response, modularity and scalability. - Industry and machinery
Forklift trucks, AGVs and industrial equipment are switching to lithium for fast charging, more work shifts and fewer maintenance stops.
Benefits of lithium batteries
- Higher energy density and power
More kWh in less volume/weight and high power delivery/absorption capacity, ideal for demanding peaks and starts. - Long service life and competitive total cost
A high number of useful cycles (depending on chemistry and usage profile) reduces the levelised cost of storage (LCOS) over time. - High efficiency and better energy utilisation
High charging/discharging efficiencies and useful DoD allow more real energy to be extracted per installed kWh. - Low maintenance and reduced self-discharge
Fewer interventions, no ‘memory effect’ and minimal losses during periods of inactivity - Safety thanks to BMS
The battery management system monitors voltage, temperature and current, protects against overcharging/overdischarging and balances cells, increasing safety and longevity.
Scalability and modularity
Easy kWh and kW growth according to future needs, with simple integration into existing and smart systems.
Sustainability
They facilitate the integration of renewables, reduce operational emissions and promote cleaner energy models. Continuous improvement in recycling and traceability reinforces their positive impact.
What type of battery is best for my business?
At TDG Ibernavitas, we speak from experience: lithium batteries, specifically lithium iron phosphate (LiFePO₄ or LFP) batteries, are currently the most robust and cost-effective technology for industrial and commercial environments.
Why are so many companies investing in lithium batteries?
Because they work. Because they last. Because they allow you to get the most out of your energy system reliably.
These are some of the advantages that our customers value most:
- High energy density
- High efficiency
- Long service life
- Immediate response time
Most importantly, this technology is proven, mature and constantly evolving. We are not talking about a promise for the future, but a real solution that is already helping many companies to reduce costs, stabilise their consumption and make their energy investment profitable.
Safety first: we leave no room for improvisation
One of the most common concerns when discussing batteries is safety. And it is a completely legitimate concern.
That is why at TDG Ibernavitas we only work with LFP systems designed to the highest industrial safety standards. We integrate solutions that incorporate:
- High thermal stability, which drastically reduces the risk of overheating.
- Explosion-proof design, structured to contain any anomaly without compromising the environment.
- Active fire protection, with intelligent sensors that detect and act before an incident occurs.
- Intelligent BMS system, which monitors each cell in real time and keeps the battery operating in optimal conditions.
The result? A battery that not only performs at its best, but does so with complete peace of mind and predictability.
Beyond technology: what impact does it have on your business?
Choosing a lithium battery is not just a technical decision, it is a strategic decision.
- If your company is electricity-intensive, you can reduce power peaks and avoid extra costs.
- If you already produce renewable energy, you will be able to store and manage it more intelligently.
- If you are planning for growth or need more autonomy, lithium batteries are scalable and adapt to your needs.
And if you are concerned about maintenance or return on investment, we are clear about this: with a long service life, low degradation and constant efficiency, this type of system pays for itself quickly and with low operational risk.
What about the environmental impact of lithium batteries?
At TDG Ibernavitas, we seek not only efficient solutions, but also sustainable ones.
That is why we chose lithium iron phosphate batteries, a technology that uses materials that are more abundant and less polluting than other chemicals on the market. This translates into:
- Lower environmental impact during the extraction and manufacturing process.
- Easier recycling and future recovery.
- Lower exposure to critical raw materials, such as cobalt or nickel.
This way, you can advance your energy goals without compromising your environmental commitments or ESG policies.
