Top Batteries Startups in 2026

We at QuantumScape are working on new, advanced energy storage technology. Our company seeks to change the paradigm in energy storage by developing a completely new class of electrical energy storage device. We were backed by top VC firms (Kleiner Perkins, Khosla Ventures, Stanford), investors such as Bill Gates, partners with the world's largest car company Volkswagen, and we recently became public. QuantumScape offices are located in the center of Silicon Valley in San Jose, California at 1730 Technology Drive.

With the launch of our flagship product, RIVER, in April 2017, EcoFlow is on track to revolutionize the way the developed and developing world interacts with power solutions. Whether you are powering a camera on a campsite, a power tool on a rooftop, an office in an RV, a water filter pump in the developing world, or preparing for the apocalypse, RIVER puts an industrial amount of power in a person’s hand. RIVER is the first of several clean, mobile, sustainable power products in development.

The product is an e-commerce website for contractors.

ReVolt Metals focuses on sustainable lithium recovery and processing, addressing the soaring demand for lithium in the green energy transition. With advanced electro-separation technology and DOE-licensed processes, we aim to recover lithium and other metals from Li-ion batteries, establishing a closed-loop, environmentally friendly metal recovery system. Our pilot line, planned for Silicon Valley, showcases our carbon-negative Li recovery process, winner of the R&D 100 Award in 2022. Join us on this journey to commercialize advanced technologies for metal recovery and contribute to a sustainable future.

TWAICE provides predictive analytics software that optimizes the development and operation of lithium-ion batteries. TWAICE’s core technology is the digital twin - a software that combines deep battery knowledge and artificial intelligence to determine the condition and predict battery aging and performance.

Adiabatic Technologies Pvt Ltd is an Indian energy company building battery systems, BMS, and chargers for the industries that won't accept downtime — robotics, defence, drones, MHE, AGV, and solar. Located in Ahmednagar, we specialize in both R&D and manufacturing of advanced energy storage solutions. We are a fast-growing team working on cutting-edge technology with real-world impact, driving sustainability, and enabling global hardware innovation from India.

Ultracapacitors with * 4x higher power density * 2x higher energy density than any competitor. This means we lower the costs 50-80% by using less materials, while at the same time offering our customers 2-4x smaller and lighter devices. This will solve crucial energy storage problems by re-generating energy, that would otherwise be lost, or providing peak or backup power in transportation, renewable energy, power quality and industrial sectors. Technology based on patented materials.

Polaron is a startup specializing in AI-driven materials design. The company focuses on accelerating the development of advanced materials for applications such as batteries, wind turbines, and other climate-critical technologies. Its machine learning algorithms leverage image data to characterize and optimize materials faster and more accurately than ever before. Polaron's platform employs generative AI algorithms trained on microstructural image data to model the intricate relationships between manufacturing processes, material structures, and performance outcomes.

Governments have had a harder time adapting to new technologies than businesses have. There are many ways that the public sector can improve the way it serves its citizens by using newer technologies and models. Smart city implementation is no longer a myth with cities like NEOM spending more than $1 trillion dollar is practical proof of traction. However what about cities that lack pockets and tight budgets implement smart city services? Trac is on a mission to change the way smart cities are defined by offering the CITY AS A SERVICE PLATFORM. We are the first to develop and deploy a plug-n-play microservice model of core municipal services through digital platforms that are data-driven and accessible via personal devices. Through this, we want to dissolve traditional tensions between residents and cities and improve sustainable-driven urban quality of life with the low-cost model.

We exist to to accelerate the monumental shift away from the supersystem of extraction, processing, and burning of fossil fuels - toward lightweight capture and consumption from entirely renewable sources. While decarbonization seems to be beyond our horizon, we remain undaunted; the long arc of energy consumption must bend toward sustainability. We believe in energy from renewable sources seamlessly integrated into everyday life. The future is silent, efficient, zero emission, flexible, distributed, and clean.
