Against the global backdrop of carbon neutrality

a new energy revolution centered on renewable energy sources and artificial intelligence is imminent. China is leading this revolution through breakthroughs in three core devices: lithium-ion batteries (LIBs)

fuel cells (FCs)

and photovoltaic (PV) cells. In the field of LIBs

energy density has increased significantly while costs have decreased; all-solid-state batteries will continue to advance toward higher energy density and enhanced safety

and material recycling technologies will reduce carbon emissions. For FCs

system lifespan has improved

costs have dropped substantially

and application scenarios are expanding from transportation to diverse systems spanning water

land

air

and space. PV technology is transitioning to perovskite

with module costs expected to decline rapidly and tandem cell efficiency poised to reach new heights. At the system integration level

the market penetration rate of electric vehicles (EVs) has nearly reached 50%

making the development trend of pure electric drive irreversible. Vehicle-to-grid (V2G) interaction

by fully leveraging the residual lifespan value of EV batteries

is set to become the most widely distributed and lowest-cost energy storage resource on the user side. Meanwhile

hydrogen energy storage technology will enable large-scale

long-term energy transfer. EVs

electrochemical energy storage stations

and hydrogen energy storage will collectively play roles in short-

medium-

and long-term energy storage

addressing fluctuations and uncertainties in large-scale renewable energy applications. By promoting scenario-driven industrial models

market-driven policy frameworks

and problem-oriented R&D approaches

the new energy revolution will ultimately form an economic ecosystem worth tens of trillions of yuan

reshaping the global energy landscape.
