Batteries

Supplying electricity on the modern battlefield is becoming almost as important as delivering fuel or ammunition. Military units now rely on drones, electronic warfare...

Towed artillery remains an important source of battlefield firepower, but modern counter-battery sensors and drones have made staying in one firing position increasingly dangerous....

GPS has become the backbone of modern navigation, powering everything from smartphones and connected vehicles to emergency services and autonomous systems. But satellite signals...

Robots are increasingly being used for inspections, emergency response, and field operations in locations that are difficult or dangerous for people to reach. However,...

The rapid spread of small drones has created a new challenge for military forces. Quadcopters and other lightweight unmanned aircraft can conduct reconnaissance, direct...

Maintaining large electrical grids is a difficult and often dangerous task. Power lines stretch across vast distances, pass through hard-to-reach terrain, and require regular...

The drone threat continues to evolve at a rapid pace. Explosive drones and loitering munitions have become some of the most significant threats facing...

Underwater missions are often constrained by endurance. Most autonomous underwater vehicles rely on batteries, which limit how long they can remain submerged before needing...

Modern military and civilian systems face a growing power and connectivity problem. Sensors, communications, and autonomous platforms all demand more energy, yet batteries add...

Drone operations are often limited by one key factor: endurance. Even advanced platforms must return to base for recharging or battery replacement, creating gaps...

Small drones are rapidly becoming a dominant feature of modern battlefields. They are inexpensive, adaptable, and increasingly used for reconnaissance, strike, and interception roles....

At first glance, diesel submarines seem to defy basic physics. Diesel engines require oxygen for combustion, yet these vessels spend much of their time...

Small units on today’s battlefield face a persistent dilemma: they need precision strike capability without exposing crews or relying on expensive platforms that require...

Frontline units and emergency responders increasingly rely on unmanned systems, yet most commercially available cargo drones still fall short of operational needs. Typical platforms...

Modern naval forces face a persistent challenge: how to monitor vast stretches of ocean without relying on crewed submarines or costly patrol cycles. Underwater...

Border checkpoints are under increasing pressure to manage rising traveller volumes, evolving security demands, and labor-intensive inspection routines. Many of these sites operate around...

As high-power lasers move from experimental concepts to practical counter-drone tools, one technical bottleneck continues to slow progress: power. Directed-energy systems require fast, intense...

Drones today are limited by a simple constraint: batteries. No matter how advanced the airframe or onboard sensors are, endurance remains capped by how...

A research team at Texas A&M University has developed the world’s first metallic gel — a new class of material that combines the strength...

A new material innovation may help solve one of the most persistent problems in next-generation battery technology. Researchers have developed a self-healing interlayer that...

A research team has developed an advanced magnet production technique that could improve the performance and efficiency of electric motors used in clean energy...

Electric air taxis may be the future of city transport, but before they take off, critical gaps in infrastructure, regulation, and airspace management need...
