Iontra

aid: iontra
name: Iontra
description: 'Iontra Inc. is a Denver, Colorado battery technology company that develops proprietary Charge-Control technology
  for rechargeable lithium batteries. Founded in 2013 and publicly launched in 2022, Iontra applies electrodynamic sensing
  and signal processing during charging to suppress lithium plating, dendrite growth and SEI-layer expansion, claiming up
  to 4x cycle life, 2x faster charging, improved cold-weather charging and better safety without changing cell chemistry.
  The technology is chemistry agnostic across Li-ion, Li-metal, Li-S, solid-state and Na-ion cells, and is delivered to OEMs
  as custom charging algorithm "recipes" flashed onto an application-specific microcontroller, or as a software-only library.
  Iontra closed a $45M Series C led by Volta Energy Technologies to launch an integrated RISC-V charge-control and fuel-gauge
  MCU. Iontra is an embedded/silicon company: it publishes no public web API, no OpenAPI, and no public SDK packages — its
  SDK is firmware delivered to OEM customers through a login-gated Document Portal under commercial engagement.'

  note: Iontra publishes no public API. Probed /openapi.json, /openapi.yaml, /swagger.json, /api-docs and /llms.txt plus the
    full /.well-known/* set (security.txt, openid-configuration, oauth-authorization-server, api-catalog, ai-plugin.json,
    agent-card.json, agent.json) on iontra.com, www.iontra.com and the Document Portal host — all 404 on iontra.com. The Vercel-hosted
    Document Portal answers 200 with an identical Next.js error-page HTML body for every path (SPA catch-all) and was rejected
    as a false positive. api/docs/developer/status/trust/portal subdomains are all NXDOMAIN. No GraphQL or MCP endpoint exists
    to introspect. github.com/iontra is an empty placeholder user account with 0 public repositories, not a company org, so
    no GitHubOrganization pointer is wired. No first-party packages on npm, PyPI, or other registries. Iontra's "SDK" is firmware
    — charging algorithm libraries built per MCU and battery, delivered to OEM customers under commercial engagement via the
    login-gated Document Portal.
