• Supercapacitors harness high power density and rapid charge/discharge capabilities by utilizing electric double-layer capacitance (EDLC) and pseudocapacitance, finding applications in hybrid vehicles (Toyota Prius), portable electronics (smartphones), and grid energy storage
• Flow batteries decouple energy storage from power generation by storing redox-active species in external tanks and pumping them through an electrochemical cell, offering scalability suitable for large-scale energy storage in systems like vanadium redox flow batteries (VRFB) and zinc-bromine flow batteries
• Lithium-ion batteries incorporate novel electrode materials and electrolytes such as high-capacity anode materials (silicon, lithium metal), high-voltage cathode materials (lithium nickel manganese cobalt oxide), and solid-state electrolytes to improve safety and energy density in applications like electric vehicles (Tesla Model S) and grid storage

Electrochemistry for smart materials

• Electrochromic materials change optical properties (color, transparency) in response to applied voltage, finding use in smart windows (Boeing 787 Dreamliner), displays, and adaptive camouflage
• Electrorheological fluids exhibit viscosity changes under an applied electric field, showing potential in adaptive damping systems (automotive suspensions) and haptic devices (touchscreens)
• Electroactive polymers (EAPs) demonstrate mechanical deformation in response to electrical stimuli, enabling applications in artificial muscles, soft robotics, and biomedical devices (prosthetics)
• Electrically conductive polymers like polyaniline and polypyrrole possess intrinsic electrical conductivity, finding use in antistatic coatings, electromagnetic shielding (Faraday cages), and sensors (glucose monitoring)

Electrochemistry in Advanced Manufacturing and Societal Impact

Electrochemistry in advanced manufacturing

• Electrochemical additive manufacturing (ECAM) enables layer-by-layer deposition of metals using electrochemical processes, allowing fabrication of complex geometries and functionally graded materials in industries like aerospace (turbine blades) and medical implants (hip replacements)
• Electrochemical machining (ECM) removes material through anodic dissolution in an electrolyte, enabling precision machining of hard-to-cut materials like titanium alloys (aircraft components) and superalloys (gas turbines)
• Electrochemical 3D printing combines 3D printing with electrodeposition for multi-material fabrication, showing potential in electronics (printed circuit boards), sensors, and biomedical devices (tissue scaffolds)
• Electrochemical surface finishing techniques like electroplating and electropolishing improve surface properties, enhancing corrosion resistance (chrome plating), wear resistance (hard chrome), and aesthetic appearance (jewelry)

Impact of emerging electrochemical technologies
