Voltage Category
Standard lithium-ion single-cell voltage. Used across EV pouch cells, portable power stations, and cylindrical formats where high energy density is the primary driver.
Voltage Spec
Overview
A 3.7V lithium battery is the industry-standard single-cell voltage for NMC, NCA, and lithium polymer chemistries — the most widely deployed lithium-ion platform across consumer electronics, electric vehicles, medical devices, and UAV applications. The 3.7V nominal voltage charges to 4.2V and discharges to approximately 2.7V, with most energy concentrated between 3.6V and 4.1V. antbattery semi-solid 3.7V cells use a reduced-liquid electrolyte design that lowers flammability risk while maintaining full voltage compatibility with conventional cells, making them a direct upgrade path for OEMs already sourcing standard 3.7V formats.
Applications
Application
EV applications use large-format 3.7V pouch and prismatic cells wired in series to reach 400V to 800V pack voltages, combining high energy density with EV-grade cycle life.
Application
Smartphones, tablets, laptops, and portable power stations rely on the 3.7V platform for its energy density, broad safety certification coverage, and compatibility with standard charging circuits.
Application
Multi-rotor UAV packs connect 3.7V cells in series — typically 3S to 6S — to match motor voltage requirements while keeping total pack weight within flight-critical limits.
OEM & Custom
antbattery supports OEM and custom development programs for 3.7v lithium battery cells and packs. Projects range from single-cell modifications to multi-cell assemblies with integrated BMS, connectors, and full export documentation.
Certifications
Products
Balanced pouch-cell platform for EV packs, UAV prototypes, and premium power systems where energy density and manufacturability both matter.
Highlights
Higher-capacity pouch cell for long-range EV architecture and pack programs that need more usable energy from the same footprint.
Highlights
21700-format semi solid cell built for portable equipment and OEM battery packs that need a familiar mechanical format with stronger energy density.

Why antbattery
Energy
Semi-solid electrolyte design enables energy densities above 300 Wh/kg — measurably higher than conventional liquid electrolyte cells of equivalent format and chemistry.
Safety
Semi-solid cells use significantly less liquid electrolyte than conventional cells, reducing the flammable material available during a thermal event and lowering thermal runaway propagation risk.
Certifications
UN38.3, IEC 62133, MSDS, and supporting export documentation available for all cells. antbattery handles the certification paperwork required for air freight and customs clearance.
OEM Support
Custom cell dimensions, capacity ranges, tab configurations, and pack-level BMS integration available for OEM programs. Sampling typically ships within 4 to 6 weeks of design confirmation.

A solid state battery works by moving lithium ions between the cathode and anode through a solid electrolyte instead of a liquid one. The hard part is not the basic electrochemistry. It is keeping transport fast, interfaces stable, and solid layers in contact while the cell cycles.
