Part 1: How Lithium Battery for Ocean Bottom Nodes Works
1.1 Ocean Bottom Nodes: Purpose and Functionality
Ocean bottom nodes (OBNs) play a pivotal role in seismic data collection by providing accurate subsurface imaging. Unlike surface-based methods, OBNs eliminate interference caused by surface waves and allow the use of both P-waves and S-waves. This dual capability enhances the clarity and precision of geological data, making OBNs indispensable for offshore oil exploration and other underwater applications. Their ability to operate in challenging underwater environments for extended periods ensures consistent data acquisition, even in remote locations.
Note: The deployment of OBNs significantly improves the accuracy of seismic surveys, reducing the environmental impact of exploratory activities.
1.2 Lithium Battery Integration in Ocean Bottom Nodes
Lithium batteries are the backbone of OBNs, providing reliable and long-lasting power in underwater conditions. These batteries are housed in sealed compartments that are detachably connected to the main cabin of the OBN. This design ensures easy maintenance and replacement while maintaining the integrity of the system. Power interfaces facilitate seamless electrical connections, ensuring uninterrupted energy supply during operations.
Lithium-ion batteries, in particular, are favored for their high energy density and extended operational life. They can power OBNs for up to 90 days without requiring recharging, making them ideal for long-term deployments. The choice of lithium battery chemistry, such as LiFePO4 or NMC, directly impacts the performance, safety, and efficiency of the nodes.
The integration of lithium batteries into OBNs ensures consistent power output, even in extreme underwater conditions. Their compact size and lightweight design further enhance the efficiency of the nodes, allowing for easier deployment and retrieval.

Part 2: Advantages of Lithium Battery for Ocean Bottom Nodes
2.1 High Energy Density and Extended Deployment Periods
Lithium batteries stand out for their exceptional energy density, a critical factor for ocean bottom nodes (OBNs) operating in remote underwater environments. These batteries store more energy per unit weight compared to traditional alternatives, such as sealed lead-acid batteries. For instance, lithium-ion batteries(e.g.NMC) offer an energy density of 160–270 Wh/kg, significantly surpassing the 30–50 Wh/kg range of lead-acid systems. This high energy density enables OBNs to remain operational for extended periods, often up to 90 days, without requiring retrieval for recharging.
The extended deployment capability reduces the frequency of maintenance operations, which can be logistically challenging and costly in deep-sea environments. By minimizing interruptions, lithium batteries enhance the efficiency of seismic data collection, ensuring continuous and reliable performance. This feature is particularly advantageous for industries like offshore oil exploration, where uninterrupted data acquisition is crucial for decision-making.
Note: The use of lithium batteries in OBNs aligns with environmental sustainability goals by reducing the need for frequent retrievals, thereby lowering the carbon footprint of underwater operations.
2.2 Durability in Extreme Underwater Conditions
Underwater environments present unique challenges, including high pressure, low temperatures, and exposure to corrosive elements. Lithium batteries are engineered to withstand these extreme conditions, ensuring reliable performance throughout their operational lifespan. Advanced sealing technologies protect the battery packs from water ingress, while robust materials resist corrosion and mechanical stress.
The ability of lithium batteries to maintain consistent power output under harsh conditions makes them indispensable for OBNs. Their reliability ensures that seismic surveys can proceed without disruptions, even in the most challenging underwater environments.
2.3 Operational Efficiency and Reduced Maintenance Costs
Lithium batteries contribute to the operational efficiency of OBNs by offering longer maintenance intervals and lower lifecycle costs. Subsea lithium battery systems typically require maintenance every 5–7 years, compared to the 14-month retrieval cycles of hydrogen fuel cells. This extended interval reduces downtime and associated costs by 23%, making lithium batteries a cost-effective choice for long-term deployments.
Additionally, the zero-emission profile of lithium batteries helps operators avoid carbon taxes, which range from $50 to $85 per ton. This feature not only supports environmental sustainability but also enhances the economic viability of underwater operations.
