Why we develop telecom sodium ion battery？
Energy use is responsible for more than 92% of telecommunications network operating costs, 5G and coming 6G will drive unprecedented increases in power consumption across the telecom network, while telecom industry as a whole has pledged to reach net zero by 2050, and the most ambitious operators are striving to do it as early as 2026, commitments to carbon neutrality that will require to optimize energy consumption. However, rising energy costs, geopolitical pressure,growing power consumption and decarbonization goals, Telecom operators are paying more attention to the costs and carbon footprint, which are reducing the consumed energy, source battery and power wisely, and more efficient operation.
- There are following technical issues of LFP battery for telecom sites
- Most telecom outdoor base stations are often unattended, which result to Li-ion batteries susceptible to safety risks under improper maintenance. Such as mechanical abuse, electrical abuse, and thermal abuse, because of these factors that thermal runaway of Li-ion battery cells, posing a fire and explosion hazard.
- Under the complex operating conditions, the actual lifespan can be significantly reduced due to factors such as ambient temperature fluctuations, charging and discharging strategies, and cell consistency, therefore the cycle life of LFP battery can be reduced by more than 60%.
- Most importantly Telecom LFP battery experience a sharp spike in internal resistance at lower temperatures, dropping their standalone discharge efficiency to a mere 50-60% at -20℃, during a real grid failure, the precious battery capacity meant to keep vital telecom gear online for as long as possible is wasted on self-heating, which drastically shortens actual network backup time.
- Direct sunlight can easily cause the internal temperature of outdoor base station cabinets to surge into the 55–60℃ range during summer. Under continuous high-temperature exposure, LFP battery experience accelerated chemical degradation and parasitic side-reactions, resulting in premature capacity fading and a severely shortened lifespan. For remote or rugged terrains where maintenance requires mountain climbing or helicopter access, frequent battery replacements trigger astronomical OPEX costs.
- There are also some disadvantages of LFP battery for telecom application
- The raw material of Li-ion battery is in great fluctuations, the supply chain of Li-ion battery is not stable, therefore the Capex and TCO are increasing. For example,from January to April 2026, the price of lithium carbonate fluctuated between 120,000 and 130,000 yuan/ton. In May, it surged to 201,400 yuan/ton. As of June 26, it is in a high-level fluctuation pattern, and the supply and demand for the whole year will only be in a tight balance.
- In 2023, the EU adopted a new version of the Battery and Waste Battery Regulation, which clearly defined mandatory recycling targets: by 2031, the recycling rate of lithium in waste batteries must reach 80%, cobalt 90%, and nickel 95%. At the same time, it fully implemented the Extended Producer Responsibility (EPR) system, requiring battery manufacturers to assume recycling obligations throughout the entire life cycle, thus ensuring the implementation of the recycling system from an institutional perspective. However, Currently, the core challenge is the excessively high cost of recycling. At the same time, the Basel Convention restricts the cross-border transshipment of waste batteries and black powder, making it difficult and costly to collect and transport raw materials. In addition, under the EPR system, there is an unequal distribution of benefits between Chinese and foreign companies, making it difficult for the industry to make a profit overall.
- In order to resolve the current challenges of LFP battery for telecom operation, we have integrated NFPP prismatic sodium ion cell and smart BMS, based on extremely safe sodium ion battery technology and advanced BMS technology, We have developed an advanced, long-cycle, intelligent, cost-effective and environmentally friendly sodium-ion battery for telecom sites.
- In 2026, we have 2 models of solar sodium ion batteries:
- Smart 48V100AH sohttps://www.highstar-sodium.com/product/48v100ah-smart-telecom-sodium-ion-battery/dium ion battery (Cabinet Mount)
- 48https://www.highstar-sodium.com/product/48v160ah-telecom-sodium-ion-battery/V160AH sodium ion battery (Rack Mount)
- These 2 models of 48V telecom sodium ion battery are primarily designed for telecom indoor or outdoor site, providing a safe, reliable, stable, and environmentally friendly power supply for telecom equipment.
Why chose telecom sodium ion battery?
- Safest NFPP SIB technology, never fire nor explosion
