  A breakthrough was made in the synthesis of Wanxiang ternary high-nickel single crystal materials

  With the continuous development of power lithium-ion batteries, consumers have put forward higher requirements for the energy density and safety of power batteries.

  With the continuous development of power lithium-ion batteries, consumers have put forward higher requirements for the energy density and safety of power batteries.

  In order to reduce costs and increase energy density, power battery companies currently tend to use high-nickel and low-cobalt ternary materials, such as: Ni≥80%. While the nickel content in the ternary material is increased, the gram capacity of the positive electrode material is significantly improved; however, the structural stability, thermal stability, safety, and processing performance of the positive electrode material will deteriorate, making its application severe. challenge.

  Another effective way to increase the energy density of batteries is to increase the charging voltage of batteries/materials. However, the increase of the charging voltage will make the structural stability of the material itself worse; in addition, the oxidative decomposition of the electrolyte will intensify with the increase of the charging voltage. Accompanied by the dissolution of transition metals and the increase of side reactions at the electrode/electrolyte interface.

  In view of the above problems such as poor thermal stability, poor cycle life and structural instability of high-nickel ternary materials, the lithium-ion battery industry generally adopts the technical route of coating or doping.

  Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charge, -40℃ 3C discharge capacity ≥70%

  Charging temperature: -20~45℃ -Discharging temperature: -40~+55℃ -40℃ supports maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate≥70%

  Coating materials are generally metal oxides, phosphides, etc. The existence of the coating layer can block the direct contact between the electrolyte and the high-nickel ternary material, and to some extent can inhibit the oxidative decomposition of the electrolyte and the transition metal. Dissolution problem. The cladding layer is generally made of inorganic oxides, which will affect the migration/diffusion kinetics of lithium ions;
