Nanomaterial-based supercapacitors for energy storage
Altair Nanotechnologies
Reno, United States
Altair Nanotechnologies, Inc., founded in 1973 and based in Reno, Nevada, has pioneered the development and commercialization of nano lithium titanate (nano-LTO) battery technology for fast-charging energy storage applications. With over $200 million in funding and 50-100 employees, Altair has focused on addressing critical limitations of conventional lithium-ion batteries through nanotechnology-enabled electrode materials. The company's proprietary nano-LTO material serves as a battery anode replacement for traditional graphite, offering transformative performance advantages including ultra-fast charging capabilities, exceptional cycle life exceeding 15,000 charge-discharge cycles, superior safety characteristics, and excellent low-temperature performance. Unlike graphite anodes that can form dendrites leading to safety hazards, nano-LTO's crystalline structure accommodates lithium ions without significant volume expansion, virtually eliminating the risk of thermal runaway. This safety advantage makes Altair's technology particularly valuable for applications requiring high reliability including grid energy storage, electric buses, and military systems. The company's ALTI-ESS (Energy Storage System) products target utility-scale and commercial energy storage markets, providing frequency regulation, peak shaving, and renewable energy integration capabilities. Altair's nanomaterials are synthesized using proprietary processes that control particle size and morphology at the nanoscale, maximizing electrochemical performance. The nano-structured titanate provides high surface area for rapid lithium-ion intercalation while maintaining structural stability across thousands of cycles. Throughout its history, Altair has partnered with major automotive and energy companies to deploy its technology in real-world applications including electric bus fleets that benefit from fast charging during route layovers. The company has also supplied battery systems for grid stabilization projects where the ability to absorb and release energy rapidly is crucial for grid reliability. While nano-LTO batteries have lower energy density compared to conventional lithium-ion cells, their superior power density, safety, and longevity create compelling value propositions for specific applications. Altair's work demonstrates how nanomaterial engineering can fundamentally alter battery performance characteristics, enabling applications that conventional battery chemistries cannot adequately address. As energy storage becomes increasingly critical for electric transportation and renewable energy integration, Altair's nano-LTO technology represents an important specialized solution within the diverse battery technology landscape.

SES AI
Boston, United States
SES AI, established in 2012 in Boston, Massachusetts, is a publicly-traded company (NYSE: SES) pioneering hybrid lithium-metal battery technology for electric vehicles and other high-energy applications. With over $500 million in funding and 200-500 employees, SES AI represents a major effort to commercialize next-generation battery chemistry that could dramatically improve electric vehicle range and performance. The company's flagship Apollo lithium-metal battery platform combines lithium metal anodes with advanced liquid electrolytes, achieving significantly higher energy density than conventional lithium-ion batteries while maintaining safety and cycle life. Lithium metal anodes offer theoretical capacity nearly ten times higher than graphite anodes used in traditional lithium-ion batteries, but have historically suffered from dendrite formation—needle-like metallic structures that grow at the nanoscale during charging and can cause short circuits and safety hazards. SES AI has developed proprietary electrolyte formulations and battery architectures that suppress dendrite growth through nanoscale interface engineering and electrochemical stabilization. The company's AI-driven approach leverages machine learning and computational modeling to design and optimize electrolyte compositions, accelerating development cycles that traditionally required years of trial-and-error experimentation. This integration of artificial intelligence with materials science and nanotechnology enables rapid screening of thousands of electrolyte candidates to identify formulations with optimal performance characteristics. SES AI has established partnerships with major automotive manufacturers including General Motors and Hyundai-Kia to develop and scale lithium-metal batteries for electric vehicles. The Apollo platform targets energy densities exceeding 400 Wh/kg, potentially enabling electric vehicles with ranges exceeding 600 miles on a single charge. The technology's nanoscale electrolyte-electrode interfaces are critical to controlling lithium deposition morphology and ensuring stable, safe operation. As the electric vehicle market expands globally, SES AI's lithium-metal battery technology could address key barriers to EV adoption including range anxiety and charging time.

Ola Cabs
Bangalore, India
Ola Cabs (simply Ola) is India's leading mobility platform offering ride-hailing, auto-rickshaw booking, bike taxis, car rentals, and electric vehicle services across hundreds of cities in India and select international markets. Founded in 2010 in Bangalore with over $5 billion in funding and 5,000+ employees, Ola has facilitated billions of rides and become deeply integrated into Indian urban transportation. The platform offers multiple ride options tailored to Indian preferences and price points, from shared economy rides to premium sedans and luxury vehicles. Ola Auto revolutionized the auto-rickshaw experience by bringing traditionally unorganized three-wheeler taxis onto a digital platform with transparent pricing and driver ratings. Ola Bike provides motorcycle taxi services for quick, affordable transportation through congested traffic. The company's rental services enable multi-hour and multi-day car bookings for intercity travel and special occasions. Ola Electric, a separate division, has become a major electric scooter manufacturer with ambitions to lead India's electric vehicle transition, operating one of the world's largest electric scooter factories. The platform's driver-partner ecosystem provides livelihood opportunities for millions of Indians, with features supporting driver welfare, training, and vehicle financing. Ola has successfully competed against global giant Uber through deep localization, understanding of Indian payment preferences (including cash), vernacular language support, and navigation optimized for Indian addresses and landmarks. The company expanded internationally to Australia, New Zealand, and the UK before consolidating focus on its dominant Indian market. With India's urbanization, growing middle class, and increasing digital adoption, Ola plays a crucial role in modern Indian urban mobility infrastructure.
