Solid-State Battery Thermal Management Patent Landscape
Solid-State Battery Thermal Management Patent Landscape in 2026
The patent corpus for solid-state battery thermal management is at a very early stage, with a single family on record as of the evidence snapshot, filed by China FAW Co Ltd in 2025. The field is effectively uncontested, presenting a wide-open technical terrain for new entrants with meaningful R&D investment.
China FAW Co Ltd holds the sole recorded position in this nascent field
China FAW Co Ltd is the only ranked applicant in the current evidence set, accounting for the entirety of the top-100 filers’ combined total — a consequence of the corpus containing just one patent family at this point.
There is no measurable tier gap because no second-tier applicant exists yet; the field is fully concentrated in a single filer by default rather than by strategic dominance.
| # | Applicant | Patent families | Share |

China FAW Co Ltd’s position reflects an early mover filing in 2025, but the absence of other applicants means this is an observation of initial activity rather than an established leadership position.
The most recent filing period is subject to publication lag, so additional families filed in late 2024 and 2025 may not yet appear in the corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2025 filing defines an otherwise dormant activity curve
The annual filing trend and technology composition together confirm that structured innovation in solid-state battery thermal management has not yet begun in earnest. One family, filed in 2025, spans two IPC branches tied to electric vehicles and battery cell technology.
Annual filing trend
No activity is recorded from 2017 through 2024; the sole filing appears in 2025. The 2025 and 2026 bars should be treated as provisional given standard publication lag — the true 2025 count may rise as pending applications publish.

Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
What the nascent structure means for R&D investment decisions
With a single family on record and no multi-year trend to interpret, the strategic signal is primarily one of open terrain. The cards below read what limited evidence exists and flag where monitoring is warranted.
Pre-emergence: no lifecycle stage determinable yet
The evidence set contains one patent family filed in 2025, which is insufficient to assign a lifecycle stage. The field sits at pre-emergence, meaning foundational claim territory — thermal interface materials, cell-pack integration architectures, coolant channel geometries for solid electrolyte stacks — is almost entirely unclaimed. Early movers filing now face minimal prior-art density.
Pre-emergenceFully concentrated by default, not by strategic depth
China FAW Co Ltd holds 100% of the top-100 filers’ combined total, but this reflects the absence of other applicants rather than an entrenched portfolio. A single family provides minimal defensive coverage. Any serious program from an automotive OEM, battery maker, or thermal-materials specialist would immediately dilute this apparent dominance.
Concentration: extremeNo co-applicant activity recorded
The collaboration evidence is empty — no co-filed or jointly assigned families appear in the corpus. This is consistent with a field at pre-emergence, where even bilateral research partnerships have not yet produced filed IP. Monitoring university-industry filings in adjacent solid-state battery programs may reveal which coalitions are forming before they enter this specific sub-field.
No co-filersChina is the sole jurisdiction on record
All one patent record is filed at the China National Intellectual Property Administration. No PCT, EPO, USPTO, or other national-phase entries appear. This means international rights are not yet being sought, either because the technology is early-stage or because broader filing strategies have not been activated. Watching for PCT filings from Chinese automotive and battery players is a practical early-warning signal.

China FAW Co Ltd: sole filer in an uncontested field
Only one applicant appears in the ranking. A leader/challenger structure cannot be drawn from the current evidence; the second card is marked as evidence pending.
China FAW Co Ltd
China FAW Co Ltd holds the only recorded patent family in this field, classified across B60L electric vehicle propulsion and H01M battery technology — consistent with a vehicle-integrated thermal management approach. Applicant momentum data is not available for this filer in the evidence set, so trajectory cannot be quantified. The filing in 2025 marks the company as the first mover on record.
families: 1No challenger on record
No second-ranked applicant exists in the current corpus. The challenger position will be populated as additional families are filed and published. Candidates to watch in adjacent solid-state battery IP include battery-cell OEMs, automotive thermal-systems suppliers, and national-lab spinouts, none of whom have yet entered this specific sub-field per the evidence.
families: —Under-served routes adjacent to the recorded filing
With only one IPC-classified family on record, the white-space evidence is not populated. The two observations below are drawn from the recorded IPC branches and plausible technical adjacencies, framed as areas to monitor rather than validated opportunities.
Solid electrolyte thermal conductivity engineering
The sole recorded family sits at the vehicle-system level (B60L / H01M10). No filings yet address the material-level challenge of engineering thermal conductivity in sulfide, oxide, or polymer solid electrolytes — a prerequisite for effective pack-level thermal management. This branch is technically adjacent, has clear engineering value for cell safety and charge-rate performance, and would fall within H01M10/05x sub-classes. Entry would require materials characterization capability alongside IP strategy.

Conventional liquid-cooling thermal interface approaches must be re-engineered for rigid solid-state cell stacks, which cannot tolerate the same mechanical compliance. Phase-change materials and compliant thermal interface layers for solid-state geometries represent a distinct design problem with no recorded families in the current evidence. Relevant IPC classes would include H05K7 (thermal management of electronic apparatus) and C09K5 (heat-transfer compositions). Suppliers of thermal interface materials are the most natural entrants.

Frequently asked questions
The current evidence set contains 1 patent family in scope. This is an unusually small corpus and reflects either a very narrow query definition or the genuine pre-emergence of this specific sub-field as a distinct IP category.
China FAW Co Ltd is the only ranked applicant, holding the sole patent family on record. It filed in 2025, making it the first mover by default rather than through accumulated portfolio depth.
All recorded patent activity is in China, specifically at the China National Intellectual Property Administration. No PCT filings or filings at the EPO, USPTO, or other national offices appear in the current evidence.
The single family is classified under B60L (electric vehicle propulsion) and H01M (batteries, cells and fuel cells), indicating a system-level, vehicle-integrated thermal management scope rather than a materials-science focus.
Based on the evidence, the field is at pre-emergence. No lifecycle stage can be formally assigned with one family on record and no multi-year filing trend. Foundational claim territory across materials, cell-pack integration, and cooling architectures remains largely open.
No co-applicant or jointly assigned families appear in the evidence. Collaboration networks have not yet formed in this specific sub-field, though adjacent solid-state battery programs have active university-industry partnerships that could migrate here as the technology matures.
