An Energy Storage integrator decided to build its own cell production line after years of buying cells from suppliers. Construction and equipment orders were moving ahead, but the search for a cell R&D leader had stalled for four months. Applicants either had limited small-cylindrical-cell experience or came from leading battery companies with compensation expectations and non-compete concerns the business could not readily accommodate.
The problem is partly how the search is defined. More than 90% of experienced cell developers are concentrated in EV batteries and consumer-electronics batteries, by industry estimates. A search confined to people already carrying an energy-storage cell title misses much of the relevant expertise.
Understand where the experience sits
China added 27.1 GWh of new-type energy storage in the first quarter of 2026, up 76% year on year. At the 2025 Energy Storage International Conference and Expo, academician He Yaling projected a cumulative storage talent shortage of 505,400 between 2020 and 2030, or around 50,500 additional specialists a year.
Industry workforce estimates for 2025 put employment at approximately 220,000–250,000. Production accounts for 80,000–90,000 people, while R&D and technical roles account for only 20,000–30,000. Oversupply in some Manufacturing activities therefore coexists with shortages in specialised development.
CATL reported RMB 18.61 billion in R&D spending in 2024 and a research team of more than 20,000. Together with BYD, it represents a substantial concentration of battery expertise; industry commentary estimates that the two may account for around half of China's cell R&D talent. CALB, Gotion High-tech, EVE Energy and SVOLT form other important pools. Pay, equity, project commitments and employment restrictions all affect how accessible these people are.
1. EV battery companies: match the chemistry and application
EV and stationary-storage cells share electrochemical foundations but optimise for different conditions. EV development often emphasises energy density, fast charging and low-temperature performance. Storage places greater weight on safety, lifetime and cost. A useful comparison is roughly 3,000 cycles for some EV applications against storage designs starting around 6,000 cycles, although targets depend on the product and operating conditions.
First-quarter 2026 storage-cell shipments reached 209 GWh, with LFP accounting for more than 97%, according to industry figures. EV experience can include both LFP and ternary chemistries. Voltage profiles, thermal-failure mechanisms and electrolyte formulations differ, and a leader moving from ternary development to LFP may need six to 12 months to adapt fully.
Look first for the relevant chemistry and development responsibility. BYD's Blade Battery work, CATL's LFP storage programmes and Gotion's LFP development are examples of technically adjacent experience. These are also strategically important teams, so candidate interest and any applicable restrictions need early attention.
2. Consumer-electronics batteries: look beyond cell size
Consumer-battery businesses have deep experience in materials, cell design, manufacturing processes and fast product iteration, particularly in cylindrical and pouch formats. A weaker consumer-electronics cycle can make experienced people more open to a new application.
Industry comparisons suggest that equivalent candidates from ATL, Sunwoda or Zhuhai CosMX may have compensation expectations 20%–30% below those from the largest EV battery businesses. Competitive overlap and the scope of restrictions may also differ. Assess the individual agreement rather than assuming that a move between applications is automatically unrestricted.
The principal technical question is scale. Consumer cells may range from a few to several tens of ampere-hours, while storage cells can range from tens to hundreds. Larger cells create different challenges in heat distribution, consistency and safety. A candidate with strong materials and failure-analysis skills may still need support in large-cell design and industrialisation.
3. Materials companies: combine scientific depth with cell engineering
Cathodes, anodes, electrolytes and separators have a major influence on cell performance—often expressed in industry discussions as determining around 80% of it. Materials researchers can bring a particularly detailed understanding of limits, failure mechanisms and combinations that improve performance.
Hunan's lithium-battery development plans identify businesses including Hunan Yuneng, CNGR, Changyuan Lico and BASF Shanshan. The relevant work spans LFP, ternary materials and precursors, as well as sulfides, lithium nickel manganate, lithium-rich manganese-based materials and sodium-ion cathodes such as layered oxides, polyanionic compounds and Prussian-blue compounds.
However, cell development also requires electrode design, electrolyte formulation, separator matching, formation, safety testing, reliability validation and production transfer. A materials leader may be better suited to a technical deputy or materials leadership role than sole responsibility for the full cell programme. Pairing that person with an experienced cell industrialisation lead can create a stronger team.
4. Universities and research institutes: distinguish the technology horizon
Potential sources include the Chinese Academy of Sciences' institutes of physics and chemistry, and teams at Tsinghua, Peking, Zhejiang, Fudan, Nankai and Xiamen universities. Their value is particularly clear in solid-state batteries, sodium-ion systems and silicon-carbon anodes.
The assessment must connect laboratory achievement to manufacturing. Results at gram or milliampere-hour scale do not by themselves demonstrate a route to cells of hundreds or even thousands of ampere-hours, consistent production or commercial yields.
Caixin reporting places many major companies' expectations for all-solid-state battery commercialisation in the 2027–2030 period. CATL and BYD research programmes have also been described through N+1, N+3 and N+5 teams, representing technologies expected to contribute in one, three or five years. A scientist suited to an N+5 programme may not be the right person to launch an LFP production line immediately.
5. Internal development with an external adviser
Where a full-time appointment remains difficult, develop a potential internal leader with experienced external support. Materials or process engineers, including people within a BMS or integration team who understand electrochemistry, may have a useful starting point. A six- to 12-month development period, supported by training with a battery business or university, can close specific gaps.
A long-standing cell supplier may also be willing to provide technical support through an agreed advisory arrangement. A senior adviser working one or two days a week can review the technical route, designs and difficult failures while the internal team develops. Any existing obligations still need to be addressed in the arrangement.
Decide the technical route before widening the search
LFP remains central to storage, while sodium-ion and solid-state development create different requirements. CATL has announced plans for scaled sodium-ion production by the end of 2026, and BYD has reported sodium-ion cycle life above 10,000 cycles. Semi-solid-state products have entered vehicles, while full solid-state scale-up is commonly projected for 2027–2030.
If the next three years centre on LFP storage cells, prioritise relevant LFP development and production experience. If sodium-ion is part of the plan, assess the candidate's sodium materials or cell work. A solid-state programme calls for a different scientific base and a different development timetable.
At UB hunter, we map the technical route, product objectives and existing team before choosing the talent pools. EV batteries, consumer batteries, materials businesses and research institutes can all contribute; the right combination depends on the work the new leader must deliver.
